Craft Health’s Pharma 3D Printer Powered by ViscoTec’s Print Head https://ift.tt/3o3Cswl Personalized medicine is one of the most exciting verticals in the 3D printing industry, especially since the technology can seriously impact customized drug development and targeted therapeutics. Ever since the first 3D printed drug received Food and Drug Administration (FDA) approval in 2016, several firms began exploring additive manufacturing technology to help create on-demand pills, reduce costs and make easier-to-swallow drugs for patients. One of them is Craft Health, a Singapore-based research and development stage pharmaceutical and nutritional supplement delivery business that relies on 3D printed solutions to simplify drug dosage. Focused on solving the challenges of complex medication regimens by streamlining how drugs are delivered to patients, Craft Health revealed its proprietary 3D printer uses a specially designed print head for viscous two-component materials by German firm ViscoTec. Craft Health is leveraging ViscoTec’s vipro-Head 5 print head for 3D printing of nutraceuticals and pharmaceuticals. The solution is ideal for accurate and precise personalized tablet manufacturing since it complies with the regulatory requirements that this type of 3D printed product demands. The ability to produce small batches of carefully tailored drugs with the dosages, shapes, sizes, and release that each patient needs has tremendous potential. When pharma and 3D printing converge to create a chemical compound that can be easily produced on-demand and on-site (at a hospital, pharmacy, or even remote areas), it’s easy to see the benefits of this healthcare segment. By simply streamlining the production process of drug manufacturing with 3D printing technology, companies can save time, reduce waste, and eventually accelerate the creation of a custom formulation for a patient. As the potential of this healthcare segment emerges, more companies will follow suit. Funded in 2019, Craft Health is an early-stage startup that uses a proprietary blend of formulations–called Craft Blends–corresponding to different controlled release profiles, all 3D printed into a single tablet using a specialized 3D printer called CraftMake. For their drugs to work, the required active ingredient is simply mixed with the formulation and the desired controlled release profile before 3D printing. According to Craft Health co-founder and COO Seng Han Lim, the brand’s CraftBlends must be printed in the desired volume or geometry, based on the individual requirements of the active ingredient. But precision and accuracy of dosing during 3D printing is the main challenge due to the compressive nature of paste or semi-solids being used.

Powered by Aniwaa In fact, the company’s founding duo, who happen to be two pharmacists, learned early on that formulating the pharmaceutical material for 3D printing was not easy. The first time they set out to try their idea on a 3D printer, the material failed to come out from the print head and shot out from the nozzle tip, causing a mess in the entire machine. This material clogging was subsequently fixed, and today, the company relies on the ViscoTec vipro-Head 5, which allows precise and accurate dosing of the material being 3D printed, and the final product to have high uniformity.
The ViscoTec print head transports two components separately from each other to the static mixing tube. They are then mixed together in a correct mixing ratio and applied layer by layer. Several advantages of ViscoTec include a stepper motor version in the print head that allows easy integration to already existing gantry systems for 3D printing. Also, the wetted and non-wetted surfaces could be clearly separated and cleaned accordingly. Always on the lookout for collaborations and partnerships, Craft Health worked with the ViscoTec team in Asia on new ideas to modify the print head to comply with any regulatory requirement for manufacturing of nutraceuticals or pharmaceuticals, said Lim. So to meet Craft Health’s needs, the wetted surfaces of the vipro-Head 5 were customized and refabricated using a low-carbon alloy of stainless steel (SS316L) material to comply with FDA regulations for a non-reactive, non-absorptive print head. Whether reducing the frequency of medicine intake or combining multiple medicines into one single polypill, Craft Health is on a mission to change the status quo of pharmaceuticals. Today, the company offers customers on-demand personalized medicine production, drug development research, and clinical trials for patient acceptability and taste evaluation. To further extend their work, the company recently moved its operations from Bukit Batok industrial park to the prestigious Singapore Science Park in the country’s south-westernmost area of Queenstown. There, the company has set up its very own R&D laboratory and clean room to produce 3D printed nutraceuticals and pharmaceutical products and remains at the forefront of innovation.

3DPOD Episode 85: Large Format 3D Printing with Poly Products’ Michiel de Brujicker https://ift.tt/3d0U3yU Having previously worked for Bond3D and Admatec, Michiel de Brujicker is now doing something very new and exciting in 3D printing. With Poly Products, he’s printing large-scale structures and parts. Using a massive CEAD 3D printer, the company makes outdoor advertising, pump tracks, parts for submarines and molds for jacuzzis. Large-format polymer 3D printing is very much a novelty in additive manufacturing. In our talk with Michiel, it also seems to very much be a business, as well. But, as Michiel’s open-hearted talk reveals, it is also difficult with heating zones, part deformation, and more issues bedeviling the team. He also talks about what applications he wants to go into, from formwork to bridges and tooling molds. Additionally, Michiel discusses what the ideal large format machines would look like. We loved this look into a new and exciting area for AM.

POP Member Showcase: 10 Monochrome Prints https://ift.tt/3d1qrl0 This month, we’re delighted to present a selection of monochrome prints created by the talented members of our Official POP community. Through utilising just one colour, our members have conveyed powerful messages combined with a plethora of printmaking techniques. Studio Turbo: How to Build a Robot “I love drawing on grids and using geometrical shapes. To me, the limitations of a strict grid in combination with only geometrical shapes are both challenging and fun,” says Raoul Wilke of Studio Turbo. This monochrome screen print was designed on a grid of 1,25mm squares. He comments further; “It was tricky to only use 1 colour and still get some kind of depth in the face of the robot but in the end I think it worked out pretty well”. So if you ever want to build a robot yourself get this blueprint, or should we say, redprint. Ashley Jouhar: Monochrome CollagesMuch of Ashley Jouhar’s printmaking is monochrome. The prints shown here are all recent works and are evidence of his passion for graphic directness. “I find the removal of colour, other than black and white to be quite liberating, as it allows the viewer’s eye to read imagery, compositions and shapes more directly. There is also a discipline with working in monochrome to create striking, impactful pictures,” describes Ashley. Each of these pieces are collages made up from found elements as well as elements Ashley has created himself. Margaret Mallows: Grass Hopper Grass Hopper is a monochrome print by Margaret Mallows created using just one colour for each of 3 variations; “A happy experiment to find a good tonal range with one colour of ink”. This tiny reduction print size 10 x 15 cm was made in several layers, with tonal values achieved with a mixture of extender, ghost printing, and roller pressure. Margaret made 3 variations of the same print for colour comparison; 4 prints each of black, sepia, and burnt sienna. Making this print gave her useful experience for future work and a taste for experimenting more. Emily Pallett: Inside/Outside Emily Pallett has been exploring her identity by looking into the term ‘don’t judge a book by its cover’. To do this she has been experimenting with old English calligraphy and letterpress type which she then turned into screen prints and book wrappings. As a book lover and a letterpress printmaker, it is important for Emily’s work to include text in some way. These pieces are the result of understanding judgement and how people treat others who appear to be different on the outside, whilst not considering what’s on the inside. Zoe Cloke: Little Houses Across the world many of us found ourselves in some form of lockdown during 2020. Trapped on our own little house islands, Zoe Cloke began a series of fine line pen drawings of houses that were sent to her. Seven were digitally captured to create a limited edition Gicleé print. Each house in the print has a story to tell; the first house was bought just before the UK went into lockdown (and was someone buying back a home that used to be in their family) and the last house was perilously close to the Californian fires and its future was uncertain. The Brooklyn Brownstone standing tall in the middle measures just 9cm in height, with the smaller houses being around 6cm. The small scale emphasises how the small actions of so many had such a big impact on changing outcomes. Becci Salmon: You & Me Most of lincout printmaker Becci Salmon’s work utilises a monochrome palette. In this piece, titled You & Me, Becci uses distorted type to create the shape of two hands. This is her first typographic print and also her largest work in size to date. Filippos Fragkogiannis: Saturnine This typographic poster from Filippos Fragkogiannis represents Saturn; a planet of commitment, routine, and structure, and Saturn Return; an event that will happen two or three times in your life which acts as “a period of getting serious about who you are, what your legacy is, and what you’re here to leave for the world”. Filippos describes; “Saturn’s action is slow, thorough, and inevitable. It is the planet of real worth, as apart from show and make-believe, and gives to all things their permanent and lasting qualities.” Mike Black: Cat Coven Inspired by an actual coven of cats printmaker Mike Black happened upon in the woods (you can see a pic over on his website), this linocut print features a trio of magical moggies conjuring under the light of the full moon. He states; “As a kid growing up on witchy staples like Buffy, The Craft, Practical Magic, and a hundred other 80s and 90s pagan influences, it’s pretty much ingrained into my psyche. So when I saw these cats and the idea hit me I just knew I had to make a print out of it!” A labour of love, this limited edition relief print took three weeks of planning and carving to reach its completion. Printed on the highest quality archival printmaking paper, it will last for years to come and would make a great addition to any spooky home. Caroline Erolin: Sleeping Badgers Caroline Erolin works predominantly in lino printing and tends to alternate between colourful reduction prints and more stark monochrome prints. Generally speaking, her monochrome work tends to be slightly ‘darker’ in mood, often referring to the cycle of life and death, depicting both the living animal and it’s skeleton. However, this piece, Sleeping Badgers, is lighter in mood, depicting a trinity of adorable badgers amongst the roots of a tree, whilst still referencing duality with the distinct above and below motif. Luke Matthews: Damn Your Eyes Damn Your Eyes was the first typographic design that Luke Matthews had printed upon setting up his OKNO shop, and it’s proven to be the most popular so far! The line comes from Johnny Cash’s recording of Sam Hall where it appears at the end of each verse; “I saw Molly in the crowd, and I hollered, right out loud, hey there, Molly, ain’t you proud? Damn your eyes!” Luke stumbled across a Japanese translation (a terrible one, it turns out) of the song online and felt this would sit nicely next to the warped, melting text that makes up most of the design. Luke concludes; “This print means a lot to me, as it’s how I started my small business, and I’ve sold more than 200 of them around the world”.

3D Printing News Briefs, November 27, 2021: Sustainability, Metal 3D Printing, & More https://ift.tt/3p82oX0 In this edition of 3D Printing News Briefs, we’re starting with stories from Aleph Farms and Orbex regarding their efforts to keep our planet healthy by, respectively, working towards net zero carbon and making an environmentally friendly rocket with 3D printed parts. Moving on, Additive Assurance has partnered with Volkswagen, and Penn State’s CIMP-3D is expanding its metal AM capabilities. Finally, we’ve got some research on using expandable graphite to modify PLA for FFF 3D printing. Aleph Farms Introduces Net Zero Carbon Roadmap Israeli startup Aleph Farms, which grows steaks from non-genetically engineered animal cells, recently introduced its roadmap to achieve net zero carbon in its operations by 2025, and through its supply chain by 2030, thus fulfilling the vow it made last year. The startup created the roadmap with partner Aimee Christensen, a climate change and sustainability strategy expert and the CEO of Christensen Global Strategies, and explains what investments and strategic partnerships will necessary to improve its business bottom line and advance its environmental goals. As part of the roadmap, which includes transitioning renewable energy and optimizing energy efficiency, Aleph Farms signed a Memorandum of Understanding (MoU) with ENGIE‘s sustainability consulting arm ENGIE Impact to ensure that its operations are net-zero compatible, and is also partnering with CE Delft to analyze the life cycle impacts of its production line and supply chain.
Orbex Developing “World’s Most” Environmentally Friendly Rocket UK spaceflight company Orbex is working to launch what it calls the most environmentally friendly space rocket in the world, the 3D printed Orbex Prime. According to a new scientific study by the University of Exeter, the carbon footprint of launching the new Orbex Prime will be up to 96% lower than fossil-fueled alternative space launch programs, and produce up to 86% less emissions, thanks to its reusable design and use of renewable, ultra-low-carbon biofuel. The study shows that the 13.8 tonnes of CO2e emissions from one launch of the Orbex Prime—including direct launch emissions, indirect emissions created by producing necessary propellant fuels, and radiative forcing (RF) effects of non-CO2 emissions at high altitude—is comparable to the annual average emissions created by a single person in the UK, and that the Orbex rocket almost completely eliminates the use of black carbon emissions. As part of its commitment to offset all emissions from the rocket and its launch operations, Orbex plans to launch Prime from Scotland’s carbon-neutral Space Hub Sutherland.
An Executive Summary of the study, “Orbex Holistic Launch Carbon Impact Assessment,” is available upon request. Additive Assurance and Volkswagen’s Partnership Moving on, Australia-based Additive Assurance, a Monash University spinout company, is partnering up with Volkswagen to develop an advanced manufacturing system for its production 3D printers, as the automobile manufacturer is actively integrating AM into its workflow and working towards serial production with the technology. Volkswagen plans to install Additive Assurance’s AMiRIS solution for quality verification at its Wolfsburg, Germany AM center, in order to “assure precise replication” of all the components it prints. AMiRIS uses cloud-based machine learning software and inspection hardware, the latter of which observes the layered build process; the software first generates a real-time defect map, then analyzes and feeds the information back to operators. With this solution, Volkswagen should be able to ensure that its 3D printed parts have consistent production quality.
Penn State’s CIMP-3D Expands Metal AM Capabilities A lot of additive manufacturing research is conducted at Penn State, and the university’s Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D) recently expanded its metal 3D printing capabilities by installing three new large-format AM systems. The additions of 3D Systems’ DMP Factory 500 powder bed fusion additive manufacturing (PBFAM) system, ABB Inc.‘s wire arc additive manufacturing (WAAM) system, and a cold spray metal 3D printer from SPEE3D are a great complement to the center’s excellent metal AM research, signaling more to come in the future. The DMP Factory 500 uses multiple lasers to form solid parts out of metal powders, and includes high-speed video, an internal camera, and other custom sensors for build process monitoring, in addition to powder recycling modules. The printer was installed at CIMP-3D to support a program focused on modernizing products for the US Army. A welding arc connected to a robot allows the freestanding ABB Wire Arc Additive Manufacturing system to build large components, as it doesn’t need to manage powders or operate in a contained space. The system is paired with its larger sibling, a laser-based robotic AM printer commissioned two years ago. Finally, the new SPEE3D printer uses supersonic gas jets to propel powders at incredibly high speeds, so it sticks to parts and quickly builds new ones. The system is fast, flexible, and economic, and can be used to repair or manufacture components in the field very quickly. Modifying PLA with Expandable Graphite for FFF Technology Finally, a team of Brazilian researchers from Universidade Federal de Ouro Preto, Centro Tecnológico do Exército, and Centro Federal de Educação Tecnológica de Minas Gerais published a paper about their work modifying polylactic acid, or PLA, filament with expandable graphite for Fused Filament Fabrication, or FFF, 3D printing purposes, and the effect of their experiments on the material’s mechanical and thermal properties. According to the researchers, FFF is the most “widespread” of the 3D printing methods, but in order to be used more for automotive and electronics applications, there’s a need for more flame-retardant filaments. The researchers added 1, 3 and 5% (wt.) of expandable graphite to commercial PLA filament, and reprocessed these composite materials into 3D printable filament, using differential scanning calorimetry and thermogravimetric analysis to determine the thermal properties. All the composites with expandable graphite achieved the V-2 rating of UL-94 flammability test, had no strong adhesion promoted between the matrix and filler in thermo-pressed specimens, but the results indicated that the PLA’s flammability was reduced.

Implementing Additive Advantages: Orthopedics https://ift.tt/3HTfIal As we’ve seen in this series, there are a number of clusters of success in 3D printing. Where we can see small, unique, drop-in, disruptive and sidestep parts, we have success. Beyond that, however, we’ve also seen that there are a lot of hopeful searches for 3D printing applications. Here, opinion often coalesces early around one opinion and this part is then made. The component could save weight and, if it was on a satellite, this would be amazing and it would work. But, outside a few critical environments where mass is a premium, the part will actually not really be as successful as first hoped. In order to break through in many more cases in which millions of items are 3D printed, we will need to seek success in stacking. Stacking is a case where we keep searching once we’ve found that one application that makes sense. With stacking, we keep looking once we’ve found our dream part for additive. With stacking, we will have many strong clusters of components that we may make successful. We will then look not just at one advantage that 3D printing can provide, but see if we can make many work together. With stacking, items can break out of the confines of the critical and make sense in many industries. To explain the benefits of stacking, let’s look at one of the biggest and fastest growing areas of 3D printing: orthopedics. In orthopedics, 3D printing:
So, these are some, but not all of the advantages 3D printing has when compared to the manufacturing techniques it replaces. Not all have to be present in every single implant, but we can see that, in the case of orthopedics, we have a lot of them. Also, if we look deeper we can see that these can be tactical, but turn out to be long-lasting, company-specific advantages. So, in orthopedics, there is a first-mover advantage to adopt AM and also long lasting advantages to be gained from mastering AM. In a lot of cases, some of the below advantages may be of import in your industry, but, in orthopedics, all of the following are relatively important. CostLet’s start with the factor that is almost never realized. We’re almost never cheaper. Really and rarely do you find products silly, important, specific or rare enough to be more expensive than a 3D printed variant. In orthopedics, we’re one-tenth of the price of (some) CNC implants because we can make a texture that promotes osseointegration easily. The cost advantage is such that it could in-and-of-itself explain why orthopedics companies are so excited about 3D printing. But, it’s not just a case of them wanting to save money per implant. Speed and InventionThey also want to be more competitive and with 3D printing they can iterate, test, and develop products more quickly. The quicker pace of iteration leads to faster generation of inventions and geometry-specific IP. But, it also means that the company can invent more shapes and test more shapes to productize the right ones. By testing things quicker digitally or with the 3D printed part, companies can ascertain, develop, design, test and patent new designs more quickly than others. They can also test more different parts or designs in destructive testing. This will let them find the right solution more often and also eliminate design flaws more readily. This is of crucial import in the orthopedics market where a single design flaw can be incredibly expensive. Fitting the ApplicationMore testing, more information, more designs and more malleable designs will make for a firm that more quickly develops the right solution for the right application. This can lead to a better solution or a better fit with the market. What’s more, this is important in their industry due to the pace of innovation and quality. Simulation3D printing also plays very well with finite element analysis, digital simulation and calculation software. Simulation that can accurately predict stresses, load-bearing capacity and more can be combined with 3D printing. This let’s you more accurately develop products faster than without a combination of simulation, design and AM. New developments such as musculoskeletal modeling will accelerate this trend. At the same time, 3D scanning may play more of a role in error analysis and the redesign of appropriate structures, which will only accelerate this development. We play better with digital tools because we are digital. CertificationsAll in all, this means that it is faster to develop new products with 3D printing in orthopedics than without it. With certification and approvals being costly, it helps that a similar logic, similar data, similar process, and the same material and process can accelerate approvals and make them less expensive.
