Emails Going to Spam? 12 Reasons Why That Happens and What You Can Do About It https://ift.tt/2G68wJw Are you worried that your emails won’t reach your customers’ inbox? That your bottom line will get a hit because of how spam filters evaluate your messages? Or perhaps you’re already seeing that your emails go to spam instead of the inbox and you’re looking for help? If any of these made you nod, then don’t worry. We’ve got you covered! In this article, we’re not only going to tackle the main question – why do emails go to spam? – but also we’re going to offer solutions that’ll help you improve your inbox placement rate. Best of all, you’ll be able to fix most of the issues listed here all by yourself as they’re related to things like how you’re building and managing your email list or constructing your email templates. Only a few will require some additional help from your email marketing software provider. So without further ado, here are the 12 reasons why some emails go to spam and what you can do to prevent them from doing so in the future. To explore this topic further, consider these resources: Table Of Contents 12 reasons why emails go to spam and what you can do about itAlthough email marketing has always been permission-based, the regulations and the definition of “consent” often varied across different countries. Because of these differences, you’d often hear about marketers who downloaded an email list from the Internet or bought it from another company, and then thought it’s OK to send them marketing emails as long as you give them the option to unsubscribe. However, that’s no longer enough. Regulations like the Canada Anti-Spam Legislation (CASL), EU General Data Protection Regulation (GDPR), and California Consumer Privacy Act (CCPA) have become stricter about how email marketers handle customer personal information. They’re clear that it’s not enough to offer your email subscribers a way out. So before you start sending your email campaigns, you should always make sure that you have permission to do so. If you neglect that, you’re not only risking that your emails will be going to spam, but you could also be liable to a fine. That’s why if:
…you should stop right now. There are plenty of perfectly good email list building methods out there you could try. For starters, here’s the list of best ways how you can build an email list from scratch. And if you’re unsure whether it’s OK to contact some of the people who’re already in your database, consider running a reconfirmation campaign. By sending an email that’s going to ask your audience explicitly if they want to stay on your list, you can be sure that only those who’re still interested in your offer will remain on the list. Not sure what these look like? Here’s one example we’ve received when GDPR came into force: Pro tip 1: If you’re finding consent management challenging, check out the GetResponse Consent fields. These will help you easily store, manage, and view all the consents that your contacts have given you. Here’s an example of what you’ll see when one of your contacts gives you their consent, e.g., when signing up through one of your landing pages. Pro tip 2: To improve your inbox placement rate and to avoid getting your emails being reported as spam, make sure to always exclude (or suppress) contacts who haven’t given you the right consent. This is especially important if in your database you’re storing contacts some of whom haven’t agreed to receive marketing emails. Pro tip 3. If you’re sending the same message to numerous marketing lists, check if your email service provider automatically skips duplicate email addresses. Not all platforms do it out of the box, so extra careful as you don’t want to send the same message multiple times to your target audience. 2. It’s not clear what your subscribers are signing up forTransparency is key, especially when it comes to building your customer base. When filling out your signup form, users should be fully aware of what kind of communication they’re going to be receiving in the future. It’s not alright to advertise one service and send emails about another one unless you’ve specified that in your web form. Or to say that you’re just collecting submissions for a competition and end up using the email database for marketing communication. Be crystal clear about what you’re going to talk about in your emails – and then deliver on that promise. When you do that, you’ll see that your unsubscribe, and complaint rates will drop. And your sender reputation will improve. Pro tip 1: Make sure that your web form, the thank you page following it, and your welcome email clearly state what your users are signing up for. Doing this early in the subscription process improves your chances of building strong relationships with your audience. And, reducing the likelihood of your emails going to spam. Take a look at this example from a brand called Further. Throughout their signup form, consent popup, thank you page, confirmation email, and subscription confirmation page they’ve made it clear what their newsletter is about, how frequent their communication is, and how the subscriber can make sure to receive the communication in their inbox. Because of this thoughtful process, they can be sure that only those who really want to join their subscription will end up in their database. Pro tip 2: If you want to lower your unsubscribe rate a good idea might be to fill out your email list description visible in your subscriber’s preference center. This will help your audience decide which lists they want to stay subscribed to and which ones they want to opt out from. Here’s what it looks like when a contact clicks the unsubscribe link in one of the emails sent by the GetResponse Marketing Team. They see all the essential information regarding their subscription. This includes the date of their subscription and the name and description of the list they’ve signed up to. 3. You’re making it difficult to unsubscribeThis one’s a red flag and one of the top reasons why subscribers report emails as spam. If someone wants to stop receiving marketing communication from a particular sender, the last thing they want to do is to spend extra time looking for a way to unsubscribe. The moment they find it difficult or lose trust in their request being processed successfully – they report the message as spam or manually move it to their spam box. In both cases, the marketer is at loss. Here’s what you should avoid:
Adding any of the above roadblocks just gets you closer to having your emails marked as spam and having them negatively evaluated by Internet Service Providers’ (ISPs) spam filters. Here’s one example of an email message I received that’s trying to bury the unsubscribe link far away in the footer. It’s something you don’t want to do in your own email communication if you value your sender reputation. Pro tip 1: If you’re worried about your unsubscribe rate being too high, consider offering your subscribers a way to opt down, lower the mailing frequency, or even pausing it for a particular period of time (e.g. 90 days). A separate email list or segment will be enough for you to divide your recipients into separate groups, e.g., those who want to receive your emails every couple of days and those who prefer a weekly roundup. Alternatively, you could also add a short description explaining why the subscriber is receiving your emails and reminding them when or how they’ve signed up for your newsletter. Pro tip 2: If you’re seeing that your spam complaints are high and you’ve followed the tips described in points 1-3, you could try providing an additional unsubscribe link right after the preheader text inside your email message. This may look like a radical move, but it’s better to have more people unsubscribing from your list rather than having them report your messages as spam. Note: Our observations suggest that people from particular cultures may have a higher tendency to click the ‘report as spam’ button. One of such countries is Russia, which tends to observe the highest average complaint rates as we’ve found in the Email Marketing Benchmarks report. Moving your unsubscribe link to the preheader may be your best bet if your target audience shows similar tendencies. Bonus ChecklistDownload this quick checklist to improve your email deliverability and start sending email campaigns that make the cash register ring. Alright, let’s go over another important reason why emails go to spam. 4. You’re not using the right email marketing softwareI know this sounds like we’re tooting our own horn, but it’s impossible not to mention a critical factor – your email marketing software. It’s not only the technology that’s enabling you to send emails to thousands or even hundreds of thousands of recipients within minutes. Your email service provider also plays a big role in delivering your emails to your subscribers’ inboxes. Let’s take our example. Here, at GetResponse, we manage your IP reputation, process bounces, unsubscribes, spam complaints, and set up feedback loops. Thanks to this, we know when an email address is no longer active, is misspelled, or when the recipient wants to unsubscribe. Once we see such addresses, we remove them from your list, so that your deliverability isn’t affected, and you don’t have to pay extra for contacts that hold no value to your business. On top of that, we also check your email lists for common issues when they’re being imported, automatically assign engagement scores to your contacts to make reengagement campaigns easier, and also help with custom DKIM configuration if you’re using your own domain. We also team up with various ISPs and anti-spam organizations (like MAAWG, EEC, and ESPC) to learn from each other how to better secure our systems and fight spammers and phishers. As a result, customers who use our platform and follow the best practices covered in this guide don’t need to worry about spam filters. Pro tip 1: One more thing that’s worth pursuing is email authentication. Setting up the SPF, DKIM, and DMARC will make you a recognizable sender for the ISP. Identifying you means they’ll be sure you’re not impersonating anyone else. It will also help you increase your domain and IP reputation and make all the good things you do “stick” to your brand. If you’re a GetResponse user and would like to learn more about how you can authenticate your domain using the DKIM, read our help guide. Pro tip 2: While designing and coding your own emails from scratch works for many out there, one of the common reasons why emails go to spam is that their HTML code isn’t clean. To avoid that, either hire a developer who’s on top of the email design game specifically (coding for email is very different from coding websites) or use an email creator (could be a standalone one or one that comes with your email service provider). The latter will help you design and edit your email templates freely (they look great and are mobile-responsive, too), without the need to bother your designers. On top of that, you’ll know your emails are designed specifically for all the most popular email clients. 5. You’re sending your email campaigns from a freemail domain (e.g. Gmail or Yahoo!)When starting their journey with email marketing, marketers often use freemail domains like Gmail or Outlook to send out their newsletters. While it’s not illegal, we don’t recommend this approach. Many mailbox providers reject bulk emails that come from freemail domains such as Yahoo!, AOL, Gmail, or Mail.ru. ISPs would rather receive messages coming from domains that have been registered by an individual sender, whom they can track back and whose reputation they can evaluate. Tracking back the individual sender is naturally not possible for freemail domains, which may explain why they are often abused by scammers and people who deliberately want to send out spam. So what should you do instead? All you have to do is set up your own company domain or create a subdomain under your existing domain and use it for your email campaigns. Even if you’re going to use it only in the from address, and not the mailing domain you’re physically sending your messages from, it’s going to help you deliver your message better. That isn’t to say that changing the from address is going to instantly change things for you. Your from address will slowly build a reputation of its own, so it’s best to gradually increase your sending volumes rather than go for a big email blast right away. Here’s how you can add a custom domain to your from addresses inside GetResponse: Pro tip: Using tools like the Spam Assassin will help you identify such common mistakes as the freemail domain in your from address. By running your newsletters through a spam checker, your chances of reaching the inbox grow considerably higher. 6. Your email frequency is offEmailing too frequently? Recipients get tired and start ignoring your emails. They stop engaging with your communication, and because of that, ISPs such as Gmail or Outlook move your newsletters to the junk folder. Sending one email every couple of months or so? People don’t remember you and deliberately ignore your emails (maybe even mark them as spam). Or they accidentally miss one or two and lose the chance of seeing your content for several months straight. As you can see, neither of these options is good for your inbox placement rates or your return on investment. The second one’s problematic for yet another reason. If you have a big email list that you contact only every couple of months, ISPs might get alerted by the sudden email blasts. Such spikes in activity might cause temporary blocks, higher bounce rates, and more emails going to the junk folder. As a general rule, you don’t want to blast emails to your whole customer base and should opt for a more structured approach. But we’ll get to that a bit later in this article. Pro tip 1: Set the right email frequency by putting together your key email marketing metrics, like the total number of conversions, unsubscribe rates, and bounce rates). Once you decide on the right email schedule, make sure to communicate it to your audience, e.g., in your subscription form or the welcome email. Pro tip 2: If you want to increase your email frequency without alerting the spam filters, start by contacting your most engaged subscribers first. Use suppression lists and exclude segments less likely to respond to your email campaigns. After you’ve managed to successfully engage your best recipients, you can start slowly including those who read your newsletters less eagerly. 7. You’re not paying enough attention to email list hygieneEmail list hygiene may sound like a funny term. But it’s a process that can have a massive impact on your email deliverability and keeping your messages out of the spam folders. Email list hygiene management is about identifying the engaged subscribers, re-engaging those who’ve become unresponsive, and getting rid of those who hold no business value. And whom do we mean, when we’re saying that they’re holding no business value? Not just those who are no longer engaging with your communication, click the unsubscribe button, or mark your emails as spam. We also mean those who’ve provided the wrong or fake email accounts or those who’ve abandoned their mailboxes. Now, you may be thinking that this isn’t such a big deal. But it’s worth mentioning that the email list churn eats up 25-30% of your database every year. And according to a recent study by Return Path, on average, marketers lose 44% of their new subscribers within the first twelve months of their subscription. And if a big part of that churn goes unnoticed because people don’t actually click that ‘unsubscribe button’ then we’re looking at a potential reason why your emails end up in spam. So what should you do? To keep your list clean – and hygienic – you should make sure your entire list-building process is flawless. That your data is collected and transferred to your email marketing software properly, and ideally, that you also use confirmed opt-in (a.k.a. double opt-in). You’ll also want to make a habit of running re-engagement campaigns. Through these, you’ll be able to win back customers who are still interested in your brand (those who just needed a little nudge) and separate those who should be removed or reactivated through another channel. Think of it this way: the more effort you put into this process ahead of time, the fewer problems regarding bad data, human errors, and low inbox placement you’ll have in the future. Pro tip 1: If your list hasn’t been cleaned in a while or you haven’t processed bounces and unsubscribes before, you should start now. The best way to do this is to use an email verification tool and set up an automated re-engagement campaign that’ll send a couple of emails to those recognized by the system as inactive. GetResponse includes ready-made marketing automation templates that you can use to carry out such a campaign. Plus it automatically identifies subscribers who don’t engage in your communication and assigns them an engagement score of 1 to 5. Here’s what one of such templates looks like: If that doesn’t work, you’ll have to choose whether you want to remove such subscribers from your list completely or try retargeting them using another marketing channel. In GetResponse, you can use easily do this via Facebook Ads as they’re fully integrated with the email lists and segments. Bear in mind that there’s no set rule for when contact should be identified as inactive. Every company needs to develop its own so-called “Sunset Policy” as it’s largely affected by your sales cycle & email frequency. In ecommerce, for example, some recipients stay inactive for the larger part of the year, but they’ll check their emails for discount codes and information about promotions around the holiday season. Take a look at this example report for one of our automated emails. We send this email to users right after they’ve filled out the subscription form in the GetResponse Resources. Notice that the bounce rate is almost 3%, most of which is caused by hard bounces (misspelled or non-existent email addresses). Removing these addresses automatically and early into the subscription will help you ensure your deliverability is unaffected, especially when you’re planning some bigger promotional activities. 8. Your emails are image-heavy (and text-light!)Email marketing is slightly different from other marketing channels. Although images do play a big role in it, they can’t dominate your newsletters. Many email marketers make this mistake: they pack their email templates with images, to make them look nicer, and spend less time coming up with the sales copy. Here’s one such example from a renowned brand. Notice that even though there’s text in the email body, it’s still part of an image. This may seem like a good strategy – after all, people like images and can read the text even when it’s part of an image. But there are two problems with this approach. One is that, unless you provide the ALT text to your image, consumers that use screen readers may have trouble reading your content. Plus, with so many email clients blocking images automatically messages that don’t have the ALT text provided look rather unappealing. Just like it would be with the following email. The second one is that ISPs like Gmail or Outlook see this a bit differently. Lots of heavy images make heavy emails and ISPs want to process as many emails as possible. By making your newsletters image-heavy, you’re making this process more difficult and resource-consuming. And because of that, they may choose to filter your messages less favorably and place them in the spam folder or even bounce them. That isn’t to say that all emails that contain heavy images will go to spam. Email marketers with high deliverability and high subscriber engagement can often get away with slightly heavier newsletters. But I’m going to assume that this isn’t you since you’re reading this article. On top of the email weight, ISPs also look at the amount of text that’s visible in your newsletters. They check the text-to-image ratio to evaluate the quality of your message. That’s because a lot of spammers want to avoid text-based content filters. In general, the more text or the higher its ratio compared to images the better. Additionally, ISPs also compare the HTML and text versions of your emails. These have to match, otherwise, the message looks suspicious, to say the least. Naturally, this doesn’t mean your emails have to be text-only. Especially given that our studies have shown that emails that contain at least one image tend to have higher average open rates than the plain text ones. So what should you do, when images need to be part of your email template? First of all, check whether your email service automatically reduces the size of images you upload into your newsletter. For example, when you add your own images into your email template in GetResponse, you’ll need to load the image editor first and save the images to have them cropped and compressed. This is different for GIFs, however, which you’d need to edit outside of the platform, using tools like Ezgif. Alternatively, when saving your files in your image editing software, make sure to use an option that’ll be called “export them for the web” or something along these lines. And if you’re on a budget or just don’t want to bother your designer, use an online tool called Squoosh. It’s really quick and can help you make your images optimized – both to be used in the email campaigns or on your website in general. Pro tip: One way to increase your text-to-image ratio is to add more copy into your footer. There, you could explain why your subscribers are receiving the email, who it’s being sent by, and how one can manage their mailing preferences or unsubscribe. This is in addition to adding the elements that are required by CAN-Spam Act in the United States and other regulations. One such element is the Impressum, which states the name and physical address of the company sending the email. Another way you can increase your text-to-image ratio is to add copy (in text, not over an image) into your email introduction and product descriptions. The same goes for creating call to action (CTA) buttons, which could be coded and styled so that they don’t look much different from what your designer would create. This is more of an UX concern rather a deliverability one (so it won’t stop your emails from going to the junk folder), but you might want to take this into consideration. Gmail, which is the most popular email client, will clip emails they consider too large. If you add too much content, a critical part of your message might remain hidden until someone clicks the “View entire message” link. To learn more about the proper way to design your email templates, consider reading our email design best practices guide. 9. You’re linking to suspicious websites (among other things)Not many email marketers realize this, but when ISPs and their spam filters analyze your email’s content, they also go through your links. If you’re trying to improve your email deliverability because they’re getting flagged as spam, here are several things to avoid:
Bear in mind that your links could be hidden in the images that you’re using. If they’re hosted on a website with a bad domain reputation, you might also get hit by email spam filters. Overall, you should check the websites you’re linking to and how many links there are in your email in general. Again, the higher the text-to-link ratio the better. As for the number of domains you’re linking to, what you should be looking for is the so-called domain alignment. In other words, in the ideal world, the domains that are used in your from address, mailing domain, and inside of your email content will all match. Pro tip 1: Before hitting the send button, make sure to analyze your emails with a spam checker, like the Spam Check tool that’s built into GetResponse. If you use this tool and notice that your score is too high (most filters are set to 5.0), try to identify the element that’s responsible for the higher Spam Score. If you’re unsure which one it is, try cutting out the content of your email one element or section at a time and keep checking if the score’s changed. This way you’ll be able to locate the section or individual element that’s causing trouble. It could just as well be a single link or part of your copy, so pay attention to all elements within your email template. Pro tip 2: If you’d like to reduce your spam score further, there’s one more thing that you can do – add the plain text version of your message into your email template. Why bother adding it? Because it’s one of the elements, ISPs use to evaluate the authenticity of your email campaigns. It can also be useful for those who prefer to read emails in their non-HTML version. Besides, this step should reduce your Spam Score roughly by 1.1 point. In GetResponse, this is added automatically to all HTML emails. But other email service providers may offer this option separately, so be sure to check it out. 10. You’re playing dirtySome marketers will do anything to increase their email open rates and get a chance of receiving a click on their link. What they often don’t realize, however, is their tactics leave their customers at loss. And even if there’s any short-term gain for their business, it often has a long-term impact on their whole email marketing program. What sort of tactics are we talking about? For example, adding phrases like “Re:” or “Fwd:” to their subject lines. Adding these elements is meant to trick the subscribers into thinking that your marketing email is just a regular massage they’d receive from a friend or colleague. Naturally, newsletters and other marketing communication don’t work this way. Although they do include personalization or a friendly from name, they’re not meant to trick people into thinking that they’re sent from an individual person in response to their previous email. How about using the so-called spam trigger words?You know, words like “buy now” or “free”. Believe it or not, most lists of “words to avoid” are now obsolete. Spam filters have evolved so much, they don’t just look at the direct use of common phrases like the ones above. Using phrases like “cheap” won’t move your emails into the spam folder. Still, there are tactics that you should avoid. Here are a few, shared by our Deliverability Manager, Martin Schwill, for Econtent:
Pro tip: Now that spam filters have become more complex, your main focus should be on increasing your email subscribers’ engagement. One of the best ways to do this is to use email automation. Automated emails are sent in response to your recipients’ actions and preferences, which is why they generate above-average open and click-through rates. There are of course other ways to increase your engagement, but we’ll go over that in a moment. 11. Your email engagement rates are lowSpam filters are also looking at how much your subscribers engage in your email communication. The more your recipients interact with your content, the better your chances of landing in the inbox. This also means you don’t have to be as cautious as those who are just starting to send email campaigns or those whose emails land in the spam folder. The opposite is also true. The lower your engagement rates are, the more careful you have to be about how you run your email campaigns. You need to put extra effort to have your emails delivered successfully. If you’re seeing that your average email marketing metrics are below the email industry benchmarks, there are a few things you should do. First of all, focus on improving your email list hygiene. As we’ve discussed in point #7, it’s critical to keep your list clean from bad or inactive email addresses. That’s why you should regularly run re-engagement campaigns that’ll reactivate and separate inactive recipients from your most loyal readers. The second thing you should consider is lead nurturing. Instead of throwing your new subscribers into the same stream of communication everyone else receives, you should treat them in a more special way. By designing a drip campaign, you can turn your new contacts from complete strangers to active consumers one message at a time. A big part of your lead nurturing campaigns will be welcome emails. They’re not only great for creating a great first impression but also for engagement and deliverability. They reach an average of 80% open rates and 25% CTRs, and can help you get your customers used to checking your emails in their inbox. You can also use welcome emails to ask your recipients to add you to their safe senders’ list. And setting up welcome emails is easy. All you have to do is either set up an autoresponder or a marketing automation workflow that’ll be sent right after a new contact joins your list. Here’s what this looks like in the GetResponse Autoresponders: Last but not least, make sure to segment your audience for all major campaigns. Rather than sending email blasts to everyone who’s on your list, pick the customer segments that are most likely to be interested in your offer. You could base this on customer attributes they’ve provided when signing up to your list or by looking at their past behavior and identifying only those who are engaged in your communication. By going for the more targeted approach you’re likely going to see higher engagement rates and won’t need to worry about missing the inbox any longer. To prove our point, just consider the results we’ve generated with one of our campaigns. We sent the very same email (the only difference is the day) to three audiences. The top one is the one our system marked as engaged, and the bottom two are unengaged subscribers. Notice how different are the unique open rates and click-through rates? And now imagine how you could improve your inbox placement rate if you only focused on those who are engaged and focused on reactivating those who are unengaged early in their journey. Pro tip: Increasing your email engagement rates takes time. If your messages mostly land in the spam folders, start sending your email campaigns to only your most engaged audience. Once you’ve managed to reach them, slowly begin to go for the slightly less engaged ones – and ideally skip those who are completely unengaged. As mentioned before, in GetResponse we evaluate your subscribers’ activity and assign them different engagement scores automatically. Here’s what this looks like: 12. Your mailing IP has a bad history recordIf you’ve gone through all the aforementioned reasons, fixed them, and your emails are still landing in the spam folder – the chances are that your mailing IP is to blame. The IP you’re sending your email campaigns through builds a reputation of its own. And this reputation stays with that IP address for months, even when nobody’s using the IP to run their email campaigns. This means that if you’ve acquired an IP address (or your email software provider assigned you one), it may have someone else’s reputation still affecting the deliverability. This isn’t usually a problem, because most email marketing providers (including GetResponse, except for the MAX plan) use a number of shared IPs to process your campaigns. In other words, the reputation is built by a number of marketers at the same time. Plus, the email traffic is directed through different channels to make sure the deliverability stays intact. Having said this, if you’re experiencing deliverability issues and you’re using your own mailing IP, this is something you should explore further Related read: Shared or Dedicated IP Configuration: Which is Right for Me? Note: It’s also possible that your IPs’ reputation gets affected by someone else who’s sending their campaigns from an address within the same IP class. This is rarely the case, but if nothing else works, you should check out the reputation of addresses within your IP class, too. Pro tip: If you’re considering using a dedicated IP address to send out your campaigns, look for an email service provider that comes with full support. GetResponse MAX customers, for example, get a dedicated account manager who overlooks their domain reputation and mailing practices to provide constant support and guidance. Pro tip: To check if your IP is listed on one of the popular blacklists, you can use online tools, like the MXToolBox. Bear in mind that not all blacklists affect your email deliverability. There are tier 1 blacklists (e.g. Spamhaus) and lower-tier ones that were created only for commercial reasons and aren’t used by ISPs when filtering your emails. In other words, even if you do find your IP or domain listed on one of them, it doesn’t necessarily mean your emails will end up in spam. Get out of the spam folder todayNow that you’ve learned these 12 reasons why your email campaigns could be going to spam instead of the inbox and how to be seen as one of the great email senders, it’s time you start improving your email deliverability.

Allegro 3D Receives Almost $1M in Grant Award to Develop Bioprinter https://ift.tt/3vsOIr5 Bioprinting company Allegro 3D has been awarded a National Science Foundation (NSF) Small Business Innovation Research (SBIR) Phase II grant for $997,692. The grant money will support the development of a next-generation high-throughput 3D bioprinter for fabricating tissue models at the industrial scale to advance drug discovery and assay development. Led by principal investigator and Allegro 3D’s CEO Wei Zhu, the project was previously awarded an SBIR Phase I funding of $299,281 in 2019. The grant was destined for research and development work on a high throughput optical projection (hTOP) bioprinter that could directly print human liver tissue models for applications in preclinical drug screening. During the Phase I grant duration, Allegro 3D focused on developing the hTOP bioprinter and learning how to use it to create 3D hydrogel constructs within a well cell culture plate. Ultimately, the Phase I stage research aimed to demonstrate the use of hTOP to bioprint in vitro functional human liver tissues using human induced pluripotent stem cells (iPSC). These models are expected to facilitate preclinical drug screening and disease studies, leading to a significant reduction in drug development costs and time to clinical use, significantly improving the public health system. Attempting to optimize and characterize its technology, Allegro 3D went on to apply for a Phase II award and announced on April 27, 2021, that it had received the funding to advance further and eventually commercialize its innovative biotechnology. As part of the SBIR and Small Business Technology Transfer (STTR) programs, U.S. startups are eligible to apply for a Phase II award once they have been awarded a Phase I grant. The federal government’s SBIR program, which the U.S. Small Business Administration (SBA) has labeled “America’s Seed Fund,” deploys more than $3 billion annually. NSF SBIR awards, in particular, disburse $200 million every year to startups and small businesses across the United States, transforming scientific discovery into products and services with commercial and societal impact. Division Director of the Industrial Innovation and Partnerships at NSF, Andrea Belz, said that the NSF funds the most creative, impactful ideas across all markets and areas of science and engineering. They also support deep technology startups that can guide basic science into meaningful solutions that address tremendous needs.
The company is a spin-off out of the University of California San Diego (UCSD). Founded in 2018 by Zhu and Shaochen Chen, Vice Chairman of the Nanoengineering Department at UCSD, the emerging bioprinting startup is leveraging advanced bioprinting technologies developed at the university to provide customers with transformational biofabrication solutions. The goal is to revolutionize healthcare innovations related to regenerative medicine, drug discovery, and biomedical research. With the growing adoption of 3D human tissue models in the pharmaceutical industry, there is a critical need for advanced manufacturing systems to enable rapid and streamlined tissue fabrication methods compatible with already established high-throughput screening (HTS) platforms preclinical drug testing. To address these market needs, Allegro 3D is developing advanced 3D bioprinting platforms and materials for in situ drug screening or assay testing directly within the wells. This approach can drastically improve biofabrication workflow efficiencies for the pharmaceutical industry and biomedical research communities. Consistent with its mission, Allegro 3D has created the first digital light processing (DLP)-based bioprinter, the internationally patented Stemaker Model D. Designed for automated direct printing in multiwell plates, the company claims its platform offers superior resolution, speed, fidelity, and throughput for printing 3D scaffolds and tissues. Allegro 3D also provides a variety of naturally derived and synthetic bioinks with great biocompatibility to support the growth and function of various cells and tissues, as well as 3D products, such as the first reported bioprinted human liver tissue that mimics the microarchitecture and cellular composition of a hepatic lobule (the building blocks of the liver tissue). Using bioprinting technology commercialized by Allegro 3D, the company founders along with fellow UCSD scientists are also researching a novel 3D bioprinted spinal cord implant that restores function in the hind limbs of rats with spinal cord injuries and has also begun printing human implants to prove the technique could be scalable to humans. Allegro 3D’s research and developments are quite revolutionary and target very specific biological applications. For the upcoming Phase II research, the company has up to two years to develop a novel high-throughput bioprinter for commercialization. Still, with so many unique bioprinting technologies to support the work, this upcoming platform is well poised to create physiologically relevant in vitro tissue models for various applications, including drug testing, assay development, therapeutics, and biomedical research.

6K to Develop Battery Materials with $25M Investment https://ift.tt/2QGoaE7 After just a few years in existence, 6K has made itself increasingly well-known in the 3D printing industry with its unique metal materials production technology. The startup suggests that its proprietary plasma process, UniMelt, is more sustainable method for making metal powders for additive manufacturing (AM) and other applications. Now, the company is driving its sustainability mission further by investing $25 million over the next two years to triple the size of its facility in North Andover, MA to the development and production of battery materials. While 6K believes its material processing technology can be applied to a number of verticals, it has two divisions dedicated specifically to some of these leading applications: 6K Additive and 6K Energy. The firm’s newly announced Center of Excellence for 6K Energy is working toward the creation of sustainable battery materials for electric vehicles, grid storage and consumer items. The planned investment will see around ten UniMelt systems deployed at the 33,000 sq/ft site, capable of producing 100 tons of material from each system per year, as 6K works on full-scale development and pilot production of battery materials. Additionally, the startup will be expanding its development team and materials testing capabilities. A recent addition to the 6K Board, former Congressman Joe Kennedy III, explained how the purported goals of the new presidential administration align with those of 6K, including the need to re-shore production in the wake of COVID supply chain disruptions:
The facility will be working to develop new materials, such as high energy density and single crystal cathode, solid-state electrolyte materials, silicon anode and others. 6K will aim to establish pilot production capabilities that will allow partners to become qualified, domestic producers of these materials. At the same time, the Center of Excellence will serve as a tool for selling UniMelt machines to customers so that they can commercialize battery materials.
It is now painfully clear that our global fossil fuel-based infrastructure needs a complete overall, with scientists now arguing that even our economic and social systems may require fundamental alterations. One of the proposed infrastructure changes is battery-powered electrification, with global lithium ion battery production capacity expected to grow from 220 gigawatt-hours in 2018 to 1.1 terawatt-hours in 2028, according to Benchmark Mineral Intelligence. However, a chapter on “Renewable Energy Resource Assessment” in Achieving the Paris Climate Agreement Goals estimates that there will not be enough lithium or cobalt available to meet the production required for renewable technology demand.
While alternatives to lithium-ion batteries, such as lithium-sulfur, may replace the rare and problematic metal cobalt, “a shift to Li–S will increase the demand for lithium because these batteries have a higher amount of lithium,” the authors explain. Instead, they believe that metal recycling will be more viable method for obtaining rare materials. So far, the recycling infrastructure is not sufficiently developed for such a project and the recycling processes for some materials can be environmentally and socially hazardous in themselves. We also know that these materials are already problematic from a geopolitical and social standpoint. Cobalt is almost entirely sourced from the Great Lakes region of Africa, where human rights violations, child labor and pollution are prevalent in cobalt mining operations. At the same time, this metal drives military conflict in the region, with Western business interests often benefitting in the end. Meanwhile, in the Andes, lithium mining water tables are being destroyed, lakes drained and ecosystems wrecked while indigenous farmers are driven from their land. Interestingly, 6K does not note any specific research into recycling materials for use in batteries, though it has demonstrated its ability to recycle metal scrap into additive powders. Due to the above mentioned issues with the existing battery materials supply chain, it would be exciting to hear that 6K could recycle scrap lithium batteries, as that will be essential to replacing existing fossil fuel-based infrastructure. Regardless, 6K does boast that its UniMelt technology is overall more sustainable than traditional cathode production plants. The company claims that, if a battery cathode manufacturer replaced its legacy process with a UniMelt platform, it could entirely eliminate wastewater, drop greenhouse gas generation by 70 percent, and cut water consumption by 90 percent. To demonstrate just how tangled the business world is, however, we can highlight that 6K also courts military suppliers and, as previously noted, the U.S. military is the largest institutional user of fossil fuels. While easing it off of fossil fuel dependence may be beneficial, aiding its other military goals may only increase its usage of these fuels in the short term.

ExOne Acquires Assets of Freshmade 3D for 3D Printed Tooling https://ift.tt/3t4iK31 3D printing businesses are reflecting an activity level not seen since before the 2014 bubble, with acquisitions and IPOs being announced left and right. Coming off of its deal with Rapidia for an office-friendly bound metal 3D printer, ExOne (Nasdaq: XONE) has announced its purchase of the assets of Freshmade 3D. The Ohio-based startup had patented a method for producing durable tooling from sand forms 3D printed on ExOne equipment. Freshmade 3D’s AMClad Tooling is a process by which 3D printed sand forms are infiltrated and coated to produce a wide range of tooling. This can reduce the time to create tools by weeks or months, while also cutting costs by 30 to 50 percent. As explained in the video below, AMClad is ideal for shorter runs or for manufacturing processes that might require metal tooling in the long run. It’s durable enough to create a usable, 3D printed bowling ball. That means that these tools can withstand such applications as vacuum forming, composite layup, compression molds, molds for urethane casting, trim fixtures, sheet metal stamping, hydroforming and more.
ExOne’s machines have been used for the production of large tools for some time. Sacrificial tooling for composite layup that washes out with water is one such application. Freshmade 3D’s approach has other benefits, however, that ExOne believes will speed up industry adoption of 3D printed sand tooling. In particular, ExOne believes it serves to benefit aerospace customers:
ExOne will not only be able to enhance its own place in the world of 3D printed tooling, but also in art and restoration applications. AMClad is already used to fabricate replication statues, exterior reproductions of architectural elements and even chrome detailing for classic cars. AMClad parts can be processed with a variety of finishes, including metal, stone and paint. ExOne points to a replica of the Liberty of Poetry, the Italian sibling of the Statue of Liberty, which was once hosted at Ellis Island and now maintained at Kent State University.

Massimo Spadari: Print Machine https://ift.tt/2SfIZ9V Massimo Spadari grew up in the Italian North-Eastern countryside, where as a child he loved to watch animals, bugs, and all forms of life. Today, the nature he witnessed throughout his childhood continues to play a big role in his life, influence his work as a printmaker. In 2014, he left his home to attend the Academy of fine arts of Venice, where he would go on to achieve a new language of expression. Here, he was able to discover himself and become totally aware of the power of the image to convey a message. At the academy, Massimo was able to dive into a pool of traditional printing techniques such as lithography, relief print, calcography, and screen printing. Living the collective lab life made provided the opportunity for Massimo to incorporate interaction and cooperation within his personal artistic research, with ‘Interaction’ becoming key to his practice as a printmaker. Soon after, he became an assistant of the etching professor, and for the last two years has worked at the academy helping and teaching techniques to other students. Metal intaglio, stone lithography, and wood relief prints, have become Massimo’s closest print friends, as they provide a slow respectful treatment to the drawing ritual. With these slow techniques, he is able to depict melancholic, yet cold landscapes, that are a reaction at the mutation of nature by humankind. His inspiration comes from different feelings, timely and spatially caged on paper. The primary purpose of Massimo’s images is to express feelings by linking himself to the observer, trying to catch the common melancholy of everyone’s feelings. During his years at the academy, Massimo has also developed other traditional printmaking techniques, including aquatint and burin direct engraving. His most used mediums are zinc and MDF plates for intaglio, and he relief prints on thick Italian Pescia paper. He is currently developing his interest in handmade books, taking part in bookbinding classes, as well as student collective projects. In 2019, Massimo exhibited with a solo expo of Engraved Works at the Kezuo Art Space in Venice, which showcased 20 prints across calcography, lithography, and relief print. Due to the pandemic he decided to open a private print studio in his hometown in early 2020. Loneliness became an opportunity for artistic research and self analysis, and Massimo was able to develop a better figurative language and a print for his master degree in graphic arts in march 2021. However, his urge to print alongside the students of the academy rose, so Massimo decided to make his lab suitable as a shelter to others, and build a fertile soil for printmakers in the area. His idea was a success, and lots of them came to print whilst the Academy was closed. Thus, Massimo’s ultimate mission was born: meeting people and printing together, in order to keep printmaking alive. “Printmaking makes us feel the power of unity and cooperation.” Printing via People of Print https://ift.tt/2DhgcW7 April 29, 2021 at 06:38AM Start Up Filament Hub Provides a Change of Pace with Membership Discount Club 3D Printing Filament!4/29/2021
