3D Printing News Briefs: June 27, 2019 https://ift.tt/2J8rwrB In today’s 3D Printing News Briefs, we’re starting with a couple of stories from the recent Paris Air Show: TUSAS Engine Industries has invested in GE Additive technology, and ARMOR explained its AM materials partnership with Airbus. Moving on, Formlabs just hosted some live webinars, and PostProcess Technologies released a whitepaper on surface finishing metal 3D printed parts. Modix is sharing a lot of news, including four new 3D printer models, and finally, FormFutura has introduced sustainable packaging. TEI Invests in GE Additive Technology TUSAŞ Engine Industries, Inc. (TEI), founded in Turkey as a joint venture in 1985, has invested in GE Additive‘s direct metal laser melting (DMLM) technology. GE Additive announced at the recent Paris Air Show that TEI had purchased two of its M LINE factory systems and two M2 cusing machines. While the financial terms of the investment were not disclosed, the 3D printers will be installed at TEI’s Eskişehir headquarters, joining its current fleet of laser and Arcam EBM printers.
Armor and Airbus Partner Up for Aerospace 3D Printing Continuing with news from the Paris Air Show, ARMOR Group – a French multinational company – was also at the event, exhibiting its Kimya materials and a miniFactory printer, as well as its new aeronautics filament, PEI-9085. While there, ARMOR also met up with Airbus, which has frequently used 3D printing to create parts and prototypes, such as an air nozzle for the climate control system of its 330neo passenger cabin. The company has now requested ARMOR’s expertise in better qualifying its materials in order to standardize its own AM process.
Webinars by Formlabs: Product Demo and Advanced Hybrid Workflows Recently, Formlabs hosted a couple of informative webinars, and the first was a live product demonstration of its Form 3. 3D printing expert Faris Sheikh explained the technology behind the company’s Low Force Stereolithography (LFS) 3D printing, walked through the Form 3’s step-by-step-workflow, and participated in a live Q&A session with attendees. Speaking of workflows, Formlabs also held a webinar titled “Metal, Ceramic, and Silicone: Using 3D Printed Molds in Advanced Hybrid Workflows” that was led by Applications Engineering Lead Jennifer Milne.
VIDEO PostProcess Whitepaper on 3D Print Surface Finishing PostProcess Technologies has released its new whitepaper, titled “Considerations for Optimizing Surface Finishing of 3D Printed Inconel 718.” The paper discusses a novel approach to help improve surface finish results by combining a patent-pending chemistry solution and software-driven automation. Using this new approach, PostProcess reports increased consistency and productivity, as well as decreased technician touch time. The whitepaper focuses on surface finishing 3D prints made with alloys and metals, but especially zeroes in on nickel superalloy Inconel 718, 3D printed with DMLS technology.
You can download the new whitepaper here. Modix Announces New 3D Printers, Reseller Program, and Executive Israel-based Modix, which develops large-format 3D printers, has plenty of news to share – first, the company has come out with four new 3D printer models based on its modular design. The new models, which should be available as soon as Q3 2019, are the 1000 x 1000 x 600 mm Big-1000, the 600 x 600 x 1200 mm Big-120Z, the 1800 x 600 x 600 mm Big-180X, and the 400 x 400 x 600 mm Big-40. Additionally, the company has launched a reseller program, where resellers can offer Modix printers to current customers of smaller printers as the “best next 3D printer.” Finally, Modix has appointed 3D printing veteran John Van El as its new Chief Commercial Officer; he will help build up the company’s partner program.
FormFutura Presents Recyclable Cardboard Packaging Dutch filament supplier FormFutura wants to set an example for the rest of the industry by not only raising awareness about sustainability, but also by stepping up its own efforts. That’s why the company has moved completely to cardboard packaging – all of its filaments up to one kilogram will now be spooled onto fully recyclable cardboard spools, which will also come in cardboard boxes. All of FormFutura’s cardboard spools and boxes are manufactured in its home country of the Netherlands, which helps reduce its carbon footprint in terms of travel distance, and the material is also a natural drying agent, so it will better protect filament against humidity.
Because the company still has some warehoused stock on plastic spools, customers may receive both types of packaging during the transition.

The researchers 3D printed two different models during the case study, with one demonstrating anterior fractured cartilage, and the right side acting as a mirror for the ‘normal ribs’ to demonstrate misalignment of the other side. The models were used to plan the surgery, involving a thoracotomy incision and more. Chest trauma often requires surgical stabilization of rib fracture (SSRF). 3D printing has been reported as useful during intricate cases in the past for creating chest wall prostheses, but not with reconstruction using standard surgical tools.
The patient studied during this research had actually been stabbed, causing the trauma to his left chest area—also resulting in cardiac arrest. Surgery was performed, but the pulmonary hernia developed later and was repaired in a second procedure. He continued to be in pain, however, especially when laughing or coughing or stretching. As surgeons prepared to restore his chest wall with plates and bicortical screws, they used 3D printed models consisting of:
The models offered a clear perspective for the surgeons regarding areas like the disruption at the costosternal joint which was causing left chest distortion. As they continued to study the 3D printed models, the doctors were able to decide on their surgical approach. The authors point out, however, that reconstruction of the chest wall is a complicated procedure, ‘fraught with difficulties,’ to include:
With 3D modeling, however, surgeons can optimize the entire surgical and possible implantation process too.
As 3D printed models can be printed from the medical facility, all the benefits of 3D printing technology are recognized from affordability in production to speed to customization—and best of all, patient-specific treatment.
3D printing holds a special place in the world of medicine as the technology has made such sweeping changes in the way medical professionals are able to diagnose and treat other medical issues too like brain tumors, examine heart conditions with cardiac patches, and even create devices like 3D printed protheses for children with undeveloped eyes—and countless other issues making life much more tolerable for patients around the world.

The anthroposphere can be defined as the part of the environment that is made or modified by humans for use in human activities and human habitats. People also refer to the anthroposphere as the technosphere. Humans have evolved over time to build more tools to navigate their environment. Technology is the crux of this. In order to navigate one’s environment, there is an implied and necessary usage of resources within an environment. To thrive, one must efficiently use their resources, but the question is whether or not humans are doing so. The circular economy is trying to establish a thought process and system of humans having a connection to their habits that cause deterioration of the world. We shall look into how the current state of humanity and the anthroposphere point towards how close we are to moving towards a circular economy. The history of human development and advancement is imbued in creation. We are a species that continuously builds. This is a testament to the human society’s sense of exploration and experimentation. We are consistently challenging the status quo and trying to make our lives better. With humans inherently trying to make the world precise or technology driven, we are applying a mindset that is narrow minded at times. The technology and innovations we create are susceptible to unsustainable production methods. An example can be taken from overproduction with the use of injection molding systems at different companies. The technology itself is great as it produces such a large quantity of items for us in a short time, but that is a downfall of the technology as well. It is super efficient, and it causes us over produce. Building a machine such as an injection molder also leads to the utilization of resources inherently. Now it is important to denote that the technology is not bad; it just leads to unintended problems in terms of sustainability, the anthroposphere, and the circular economy. This is the internal debate of innovation and technology. We are trying to advance society, but we may be digressing it if we use all our resources. There is only a finite supply it seems. How does Human Development relate to the Circular Economy In terms of humans, I think a good amount of people in the developing world are okay in terms of life standards. This is granted a generalization, but there is validity to this. There is another opposing statement that occurs from this frame of reference: Life in underdeveloped nations is affected by developed nations having better standards of life. This does not necessarily bode well for the whole anthroposphere and the circular economy. It also seems unlikely that everywhere on Earth will have an equal distribution of resources and technology development. So how do we still work on this ideal of a circular economy when things seem unlikely? If we want to live the ideals of a circular economy to better the anthroposphere, various nations should be more focused on producing what they can based on their environment. Would this be good or bad though?
Based on the issues brought up today, I will be doing more research. I believe the importance of localization in production is a major key within our anthroposphere. These are some basic questions and assumptions I have. I will be researching and providing statistics on various items within industrial waste as well as nations that are focused on localization of their production and how this contributes to the overall anthroposphere.

With liquid metal 3D printing, the authors can create ‘stretchable’ 3D integrations formed into ‘diverse 3D structures.’ As an example in this study, they create a reconfigurable antenna. Deformity in devices is a focus here, centered around applications in ‘freeform electronics’ like:
Previously, there have been challenges in finding suitable materials for such devices that require movable parts that are also a comfortable fit for the consumer, or easy to manipulate as functional objects. The authors point out that brittleness is often an issue, although conductive materials have been developed like wavy metals, metallic networks, and a variety of composites. While promising, such methods are not always scalable to 3D printing, and resolution may be an issue.
The researchers discuss liquid metals like eutectic gallium-indium alloy (EGaIn) and gallium-indium-tin alloy (Galinstan), both stretchable materials that also exhibit low levels of toxicity and very little volatility. In comparison to solid metals, they also demonstrate excellent conductivity. While microfluidics or lithography can be used for patterning the liquid metals, their structures are limited to the 2D realm. Using a fine nozzle to print liquid metal under ambient conditions, the authors are able to create high-resolution structures. The use of narrow metallic filament allows for free-standing structures to be fabricated from liquid metal; in fact, they can even be lifted by the nozzle and moved. The high-resolution antennas were 3D printed as samples for the research, using a nozzle mounted to a syringe, and a substrate placed on the five-axis stage. The team also created free-standing structures of electrodes, allowing for minimization of interconnections—and ‘an aim toward higher integrations for miniaturized devices.’
While many industrial users are enjoying benefits such as the ability to build complex geometries that are strong yet lightweight, metal is being explored as the strongest medium for 3D printing, whether in creating porous metallic biomaterials, automated sheet metal production, or patented metals with high carbide content.

After opening remarks by Smartech’s Kirsten Mulherin Dr. Behrang Poorganji of GE started his keynote. Dr. Poorgangji is the Director of Materials Technology at GE Additive. He took us through the crucial role that materials play in metal 3D printing. In this informative presentation, he tooks us through many different elements of designing and developing materials for 3D printing. As well as examples of cases in aerospace and inside GE itself he also discussed 3D printing for medical implants. He gave us an overview of common 3D printed materials as well as newer titanium alloys. We were also told of specific alloys for titanium and nickel superalloys as well as super exciting development such as TiAl (titanium alumide). He took us through many of the process parameters in metal 3D printing as well. We got a really good overview of many of the different elements affecting your 3D printed part. From things such as the powder source, powder size, powder composition, and powder reuse procedures to the spot size, laser powder, laser travel speed and dwell time to elements such as your hatching strategy and recoating parameters. Later he also showed us how tearing and solidification cracking that is caused when the melt pool solidifies. He mentioned that understanding this behavior was key to designing and developing good designs for new alloys. He also took us through how powder characterisation could be aided by computer vision. When then a “physics informed process model” was coupled with “multivariate probabilistic optimization” in process development was combined with process control and analysis we could have physics based machine learning lead us to new powders and parts. Dr. Poorganji’s explanations were really an eye opener for many to the many different elements that control for a metal build. The huge number of variables in 3D printing processes must have given many pause for thought, especially those who perhaps were a bit too optimistic about their 3D printing implementation. Besides giving us a great update on the advances of materials it provided us with a very educational overview of what it takes to manufacture with metal 3D printing. This was a leitmotiv for the entire day with speaker after speaker returning with information from 3D printing’s frontlines. The day was a chorus of speakers who were all filling us in on the details and difficulties of manufacturing using 3D printing. It was really refreshing to hear so many spot-on presentations that brought real realism and knowledge to the floor. Gone were the hypemasters with their dreams on the desktop and overclaim. Here was real realism, real information and people preaching caution and careful progression. Everyone, to a man, was realistic and preached realism and shared information that was useful. This day really warmed my heart. I didn’t get to see everyone but Hyundai Motors’ Shinhu Cho continued in this vein by showing us all of the relevant examples of 3D printing in automotive. From competitors, race cars and one-off automobiles he gave us an excellent overview of the latest implementations in 3D printing for automotive. Clear examples were discussed and limitations and progress were explained well to us all. Next was Manuel Michiels of Materialise. He also gave an excellent presentation that really imparted knowledge on everyone. In his case, his talk was enhanced by great graphics and movies showing us what it would take for us to make qualified aerospace parts. He took us through yields, scrap and the actual process of producing parts that fit specifications. In his opinion, it all starts with the right application. He felt that a strong focus on process engineering and productivity would be important as well. Research demonstrated that half of part failures may be accounted for by lack of knowledge. He showed a visibly impressed room how in Magics you could now see FEA simulations that showed part stresses. He also took us through the role that software could play in saving money in production as well. Julien Cohen works for Eaton in their 3D Printing Center of Excellence. He also gave a really educational presentation that showed us how we can go from just printing parts to having a robust manufacturing process in place. He mentioned that going from one part to many and from prototypes to manufacturing was “not a linear progression.” He told us how important it is to “select the right parts for additive.” Multidisciplinary teams were key to avoiding costs and issues later in the process. A real eye-opener was the assertion that in the development of manufacturing processes you were going to spend “less money and time on printing” and more on optimizing “pre and post processes” such as planning and post-processing. He showcased parts that they will be 3D printing for Airbus for use on aircraft and an innovative Ram Air Valve Assembly that was a great example of DfAM and took 22 parts and reduced it to one component with a mass reduction of 10%. Julien maintains that the Digital Thread is crucial for traceability especially in areas such as aerospace. Julien also told us that the “process is the material” and that laser power, scan speed, spot size, layer thickness, raw material as well as gas flow change your part. He talked about quality management as well. He mentioned that like a lot of people in 3D printing he does not like STL and presented the interesting point that many engineers do not realize how edges in an STL could effect fatigue life in the final part for example. As well as design he discussed data management, manufacturing and process design in a great talk. Olivier de Deken of mass customization software company Twikit talked about how 3D printing could enable mass customization in automotive. The company that developed the BMW Mini mass customization software, and he went into how this works. He gave us a look into the Twikbot and how you can set parameters in that tool. He told us how Twikit was also focusing on orthotics and prosthetics as well as lifestyle products. He spoke about people “wanting their own car” and that it wasn’t about configuring but “really about making your own dashboard, making your own textures, making your own car fit you.” Made to fit seats was another thing Twikit is excited about. He also spoke about individualized parts for car-sharing companies. He talked about how CAD and design itself is completely changed by individualization. Albert Sutiono of NAMIC then went on to give a presentation on the combination of the industrialization of 3D printing and the circular economy. He detailed Singapore’s 200 million investment in 3D printing and 3D printing startups such as Siege Advanced Manufacturing and Bralco. Singapore really seems to be investing in and generating national startups in many different areas and it looks like the ecosystem may be developing. Albert looked into technical and business challenges for 3D printing including the high cost of materials and lead times. Lack of integrated end to end workflow software and lack of commercially available affordable metal printing, in situ process control and smart post-processing were also limiting. Standards is also something that needs to be addressed. Albert then discussed and explained the circular economy and how this may be enabled through 3D printing. All in all, it was an interesting exploration about how our technology may fundamentally change the way we consume.

Now, their latest market analysis, ‘Manager’s Guide to Additive Manufacturing in the Oil and Gas Sector,’ is meant to address end-user concerns. The report explains that investors for oil and gas are ready to buy into the AM market upon a better outlook for their industry after ‘a challenging period.’ Like so many other leaders in manufacturing and production, many in oil and gas seek to take advantage of the massive benefits offered by AM technology. While affordability is a major boon, obviously, 3D printing and AM processes also allow for the creation of new products that may be stronger yet lighter in weight—and previously impossible to create without the advent of such technology. Complex geometries can be created, turnaround in production is often exponentially faster, and parts—as well as refinement of designs—can be completed without a middleman. Investors in areas like oil and gas are now also becoming more interested due to the successful integration of AM in other applications like aerospace, automotive, and medical.
The report is available for licensing for $695, and includes guidelines regarding parts requirements, hardware that is relevant to the oil and gas industry, the best materials and parts for use, and also ‘a critical analysis of the advantages from implementing additive manufacturing in rapid and multiple iteration prototyping, tooling (including jigs and fixtures) and direct part production.’ If you are a part of a company currently using or considering integrating AM practices, you should find the guidelines beneficial. SmarTech expects that suppliers of AM technology would also find the study helpful—although they may also enjoy ‘The Market for Additive Manufacturing in the Oil and Gas Sector 2018-2029.’ This analysis is broader and provides a more expansive ‘forecast’ of the supply chain market. SmarTech has also released another new report, ‘Manager’s Guide to Compact Industrial Metal 3D Printers,’ targeting end users and machine shops. Here, the analysts explain that they see metal printers best described today as compact industrial metal 3D printers, offering the following benefits to industrial users:
The report also compares more traditional technology to 3D printing, like CNC machining. They also mention companies heavily involved in 3D printing with metal such as: SmarTech expects both accessibility and affordability to continue for 3D printing with metal, opening it up to new markets, and offering users an ‘increasing number of options.’ Additional reports will be released in July:
SmarTech has provided invaluable insights over the years, from analyses regarding nanometals to projections about the medical realm, and even industries like eyewear or aerospace markets.

While there have been some forays into fabrication with meat, most viable production of food has related more to extrusion of sweets, breads, and items more conducive to being expressed through a nozzle. The authors point out that some of the greatest benefits in 3D printing can be translated to use with food as so many consumers today have special dietary needs—and 3D printing technology allows for complete customization, even with the possibility of adding specific vitamins to food, along with flavors and different structures. Food customization is certainly nothing new, as chefs around the world have been creating special dishes for eons; however, ‘artisans’ today are often challenged in creating one-of-a-kind dishes as such an exercise can be cost-prohibitive.
So many different health conditions can be addressed too, and especially for individuals who may have trouble eating, chewing, or swallowing their food. The research team explains that the greatest potential for customized food lies in 3D printing techniques such as:
Their number one choice for creating food, however, is a natural one, with extrusion:
Significant challenges are still present, however, regarding precision in fabrication, performance in processing, and issues with flavor, structure, and ‘binding mechanisms.’ So far, most processing of meat in 3D printing has been in a slurry form, which makes sense for extrusion; however, this may not be conducive to presenting a gourmet product by any stretch. The addition of other binding components, however, like gelatin, should improve meat processing. Techniques such as electrospinning may also be beneficial, resulting in meat that is the desired shape and size, created of strong micro-fibers. Electrospinning can also be more conducive to good flavor due to the fibrous advantage. Microencapsulation is another technique that could be useful as it compresses vitamins and minerals and oils together, feasibly with a multi-print head system.
3D printing and food are one of the most tantalizing subjects, and while the fabrication of meat is certainly an interesting concept, researchers over the past few years have also brought 3D printed chocolate, pancakes, a variety of savory items, and so much more to our attention. Ultimately, consumers should have much more control over how their food is processed and made at home, as well as in restaurants, and many institutional settings. What do you think of this news?

Tissue engineering (TE) is a broad field today and one that is expansive with research and many different goals—most of which end in the ultimate discovery of a way to create sustainable bioprinted organs for transplantation. In creating or regenerating tissue, scientists usually work with scaffolds, living cells, and other ‘bioactive factors.’ Structures like scaffolds must be biocompatible, and obviously non-toxic too if they are being implanted into a human patient. Polycaprolactone (PCL) is a commonly used polymer in creating scaffolds, suitable due to features like:
The researchers explain that extrusion-based cryogenic 3D printing (ECP) is gaining more popularity as a choice for bioprinting because it allows for greater strength in scaffolds, whether they are made of collagen, chitosan, PLGA, or other materials. In this study, the authors used ECP to fabricate PCL scaffolds and then study the results. To ensure success in printing, the researchers relied on several different treatments, to include using a rough-surfaced glass slide as a collector, adding a transitional path at the corners of the adhesive area, and scrubbing slides with ethanol, to begin with. Porosity was measured, with results showing an increase due to ‘widening of filament offset.’ In terms of measuring biocompatibility, the researchers found that while cell attachment was ‘not well promoted’ at first, cell proliferation was ‘effectively facilitated’ because of the rough surface and porosity of scaffolds.
Tissue engineering takes many forms today, from heart tissue engineering to bone tissue engineering to tailored skin grafts. What do you think of this news? Let us know your thoughts!
