3D Printing News Briefs, November 24, 2021: 3D Printing Steel, Glass, Skin Models, & More https://ift.tt/3xllgpp In today’s 3D Printing News Briefs, we’re starting with a roundtable discussion on AM workforce development. Then we’re moving on to research, first about 3D printing a better steel, and then 3D printing glass at the nanoscale. Finally, CTI Biotech won an award for its 3D bioprinted skin model, and the winners of the purmundus Challenge were announced at Formnext 2021 last week. AM Workforce Development Roundtable with Secretary of Commerce The AM industry has grown up to 30% over the past five years, but it’s having trouble filling the thousands of new positions requiring technical skills. America Makes and 3D printing consulting firm 3Degrees recently led a round table discussion on additive manufacturing workforce development at technology accelerator mHub, welcoming partners who are developing training around the country, in addition to local and national government representatives, including US Secretary of Commerce Gina M. Raimondo. During the visit, everyone celebrated the completion of the pilot Advanced Manufacturing Experience (AMx) course in Chicago, an immersive AM apprenticeship program led by 3Degrees and nonprofit West Side Forward to train students between 22-50 years old on the West Side of Chicago. Several of the program participants attended the roundtable and shared their experiences, which included tours of facilities like Renishaw and Impossible Objects, in-person instruction, mentoring relationships with Siemens Energy, EOS, Desktop Metal, Met-l-Flo, Dyndrite, and Forecast3D, and taking a guided tour of RAPID + TCT.
Researchers 3D Printing a Better Steel A team of researchers from Stony Brook University published a paper about their work developing a more corrosion-resistant 316L stainless steel material, which is often used in naval applications. The study focused on the connection between corrosion behavior and the material structure in laser 3D printed 316L stainless steel, and the team used multimodal synchrotron X-ray techniques at Brookhaven’s National Synchrotron Light Source II (NSLS-II) to find new connections between print parameters and the material’s defect state; samples were printed at Penn State, and correlative electron microscopy was performed at Brookhaven’s Center for Functional Nanomaterials (CFN). These research findings could help make a more corrosion resistant stainless steel by engineering its material defects at the nanoscale.
3D Printing Glass at the Nanoscale Glass qualities are often tied to the applications in which the material is used, and 3D printing is capable of fabricating parts with a vast variety of geometries, but because higher processing temperatures are needed to form glass than plastics, it got a late start in the industry. The feature resolution for glass 3D printing is still limited to micrometers, but a pair of researchers, hailing from Penn State and the University of Padova in Italy, recently published a paper on 3D printing glass at the nanoscale, stating that they were able to print “silica glass components with a resolution below 200 nm.” The method they used for their proof of concept was based on two-photon polymerization, or 2PP, and they experimented with a “commercially available polyethylene glycol (PEG)-functionalized colloidal silica with an ~10 nm dimension.”
3D Bioprinted Immune Skin Model Publication Wins Award Last year, cell therapy research startup CTIBiotech unveiled two bioprinted full skin model technologies for skincare applications, and the resulting research publication, developed with BASF’s Care Creations, won the prestigious Henry Maso Award at the International Federation of Societies of Cosmetic Chemists (IFSCC) 2021 conference. BASF and CTIBiotech have been working together for several years, and the 3D bioprinting methods developed at CTIBiotech will allow scientists to produce copies of predictive full skin human tissue models containing macrophages—which monitor the skin’s microenvironment for signs of tissue infection, injury, or cell stress—from the human immune system, while BASF scientists will use the technology to choose the best ingredients and bio-actives for advanced skin care applications. CTIBiotech’s 3DBioprinting Manager Maxime Lègues, who presented the original work at last year’s IFSCC Congress before it was published, will receive a scholarship to attend the 2022 IFSCC Congress to receive the award in-person.
Formnext’s 2021 purmundus Challenge Last week, the eight gold trophy winners of the annual international purmundus Challenge 3D and 4D printing design award were announced at Formnext 2021. Sophia Lindner from act’ble GmbH, which is working with athletes to develop a new pointe shoe for ballet and contemporary dance, won first prize for the patented New Pointe Shoe Sole concept, which is said to last five times longer and reduce physical pain. Ramon Mañas with Odisei Music SL took second for the 3D printed Travel Sax, which is said to be the world’s smallest, most lightweight electronic saxophone and is already being played by 1,200 customers around the world. Jamie Cook, Henry Neilson, Theo Clarkes, Mark Brown, Jess Lewis, and George Jary from HEXR, the already award-winning 3D printed custom-fitting bicycle helmet, won third place for the helmet, which combines safety and comfort because it’s made to measure. Five special purmundus Challenge awards were also presented at Formnext 2021:
