3D Printing Briefs, November 12, 2022: Composites, Bioprinted Breast Tumors, and More – 3DPrint.com

Business, aerospace, bio-printing and more are on the agenda for today’s 3D printing briefs! APG has adopted Tritone’s MoldJet technology, Austal USA oversees an AM Center of Excellence in Virginia, and 9T Labs is working with Purdue University to advance the use of composites for structural aerospace applications. Then researchers bioprint breast cancer tumors and treat them, and Microsoft uses Shapeways to 3D print adaptive props for users with disabilities. Finally, 3Doodler introduced its latest two sets of 3D printing pens.

Alpha Precision Group adopts MoldJet by Tritone

Based in Israel Tritone Technologieswhich enables industrial throughput of precise 3D printed parts with metallic and ceramic materials, announced that the Pennsylvania-based company Alpha Precision Group (APG) has adopted its technology across the acquisition of a Tritone Dominant industrial 3D printer from its own plant in Pennsylvania. The Dominant uses the company’s MoldJet technology, which is described as “powderless” and has been developed to produce large quantities of high-density parts with complex geometries from a range of metals and ceramics. As Tritone explains, MoldJet enables parallel 3D printing of parts of different shapes and sizes, and for different applications.

“We are extremely pleased to see Alpha Precision Group’s commitment to investing in our Dominant system and bringing this cutting-edge technology to its customers. Partnering with this technology leader marks an important and strategic milestone for Tritone as we enter the North American market,” said Omer Sagi, Vice President of Product and Business Development, Tritone Technologies. “We look forward to working with APG to expand access to our technology and suite of applications and materials.”

Austal USA oversees the AM Center of Excellence for Underwater Parts

Australia United Statesa Mobile, Alabama-based branch of an Australian shipbuilding company and defense contractor Australia, is involved in a new 3D printing venture. Electrawatch, a company acquired in 2018, oversees the new Additive Manufacturing Center of Excellence (AMCOE) in Danville, Virginiawhich is housed in the new Center for Manufacturing Advancement on the campus of the Institute for Advanced Learning and Research (IALR) and will focus on 3D printing submarine parts for the US Navy. Each printed part will need to be certified by the Navy before being implemented in the structure, which is why the new AMCOE in Virginia will be a great help. As Larry Ryder, Vice President of Business Development and External Affairs for Austal, explained in a video interview with NBC 15 News, parts that Austal previously had to spend top dollar to ship can now be printed on demand, reducing costs, enabling stronger and lighter parts, and helping solve supply chain issues. He also said it’s possible a similar AM facility will come to Mobile in the future.

“This is an effort by the Navy to bring together a consortium of universities and industries that can tackle the issues of the submarine industrial base supply chain,” Ryder said of the AMCOE.

“There’s a lot going on, and I think we’ve proven in the way we build ships that we’re on the cutting edge. We’re always looking to see what’s new and how can we we do things better and more efficiently.

9T Labs and Purdue Collaborate for Composites in Structural Aerospace

Swiss company 9T Labs AGa leader in the automated and digital mass production of continuous fiber components, announced its collaboration with Purdue University in Indiana to research and test the potential of large-scale manufacturing for aerospace structural composite applications, using hybrid Additive Fusion Technology (AFT) from 9T Labs. The solution automates manufacturing by combining 3D printing with the overmolding speed of bulk molding compounds (BMC). It is an economical option for continuous fiber preforms in medical, robotics and transportation applications. The tools and resources needed to analyze, simulate and test the performance of composites are all located at Purdue’s Composites Manufacturing and Simulation Center (CMSC) and 9T Labs worked with the university to set up the application workflow for efficient manufacturing of high-performance parts using BMC chips and continuous-fiber 3D-printed preforms.

“Traditional composite manufacturing is expensive, wasteful and limited in its geometric freedom, especially for small-scale applications. We are setting a new standard in composite manufacturing that allows us to produce structural composite parts as easily as metal parts. Our new partnership with Purdue University is a significant step towards making this technology more widely available and accessible within the next 12-18 months,” said Yannick Willemin, Head of Marketing and Business Development at 9T Labs.

Researchers Bioprinting and Treatment of Breast Cancer Tumors

The development of bioprinted models could open the door to entirely new ways of understanding the tumor microenvironment and the body’s immune response. Image courtesy of Patrick Mansell/Penn State.

In a new study, a team of Penn State successful researchers bio-printed cancerous breast tumors, and were then able to cure them. This is a scientific first that will help scientists better understand the disease, which is one of the leading killers worldwide. They used suction-assisted bioprinting to precisely locate the tumors in 3D and create the tissue, which was then shaped into a multi-scale vascularized breast cancer tumor model with blood vessels. As explained in both Biomanufacturing and Advanced functional materials, the team validated the accuracy of their model by treating it with doxorubicin, a drug often used to treat breast cancer, and after finding that it responded favorably to chemotherapy, the bioprinted tumor then been tested with a cell-based immunotherapeutic treatment; the cells inside generated a positive immune response.

“This will help us understand how human immune cells interact with solid tumors. We have developed a tool that serves as a clinical test platform for the safety and accurate evaluation of experimental therapies. It is also a research platform for immunologists and biologists to understand how the tumor grows, how it interacts with human cells, and how it metastasizes and spreads in the body,” explained Ibrahim Ozbolat, professor of engineering sciences and mechanics, biomedical engineering and neurosurgery. at Penn State and the lead author of the study.

“Our model is made from human cells, but what we’re making is a very simplified version of the human body. There are many details in the native microenvironment that we are not able to replicate, or even consider replicating. We aim for simplicity in complexity. We want to have a fundamental understanding of how these systems work – and we need the growth process streamlined, because we don’t have time to wait for tumors to grow at their natural rate.

Shapeways 3D Printing Add-ons for Microsoft Adaptive Accessories

When Microsoft was developing its new Adaptive accessoriesthis chose Shapeways as their 3D printing partner to customize add-ons, as the company is dedicated to empowering all individuals and promoting an inclusive environment. Each piece in the range is highly adaptable and easy to use, and designed in partnership with the disability community, so anyone who has difficulty using a traditional keyboard and mouse can create the best personal setup, use their applications and increase productivity. . Users can customize the adaptive mouse with mouse tail and thumb support, and a central hub and new wireless buttons allow replacement or augmentation of traditional keyboards. You can also 3D print your own mattress topper.

Open source 3D files for these customizable adaptive props are available for download at Shapeways Marketplace. Once you have chosen a mouse tail or button design, Shapeways will 3D print the part using selective laser sintering technology (SLS) and Nylon 12 [Versatile Plastic]. There are several colors to choose from, including white, blue, pink, yellow, red, and more, as well as several finishes, such as Natural, Premium, and Smooth.
