Brief information on 3D printing, September 24, 2022: software, metal 3D printing, and more. – 3DPrint.com

We start first with software in today’s 3D printing briefs, then move on to 3D printing and ceramic and metal business. We will end with the use of 3D printing to make scientific data more accessible.

Desktop Metal Upgrades Live Sinter Software

The metal part on the left shows how a metal part deforms in the oven after 3D printing, while the part on the right shows how a part design modified by Live Sinter gives the desired result.

In 2020, Metal desk first presented his Live sintering solution, a multi-physics simulation software application that automates sinter-ready 3D printable geometries, supports, setters, and more to enable repeatable volume production of end-use metal parts. Now the company has announced significant improvements to the tool, which is used by more than a hundred companies around the world. After scan-based adjustments, Live Sinter corrects complex distortion effects in as little as 20 minutes, so parts are within 1% of target dimension and avoid warping, distortion, and distortion. other common sintering problems. Users can also fine-tune simulation results based on one or more scans to ensure greater accuracy in the production of metal binder jetting parts.

“In the field of sinter-based additive manufacturing, Live Sinter is unique for its ease of use and functionality. No other solution offered today combines our powerful and fast multi-physics simulation with sweep-based adjustments and automated support and setter generation,” said Ric Fulop, Founder and CEO of Desktop Metal. “Customers continue to tell us their absolute delight with this tool, and we look forward to continuing to invest in advancing Live Sinter to make sinter-based manufacturing accessible to an ever-widening audience, including metal injection molding customers.”

Keselowski Advanced Manufacturing installs two EOS M400-4 printers

Keselowski Advanced Manufacturing LLC this week installed two more EOS M400-4 3D printers for a total of twenty additive machines at the manufacturing site.

Continuing to accelerate its integrated growth in advanced manufacturing, Keselowski Advanced Manufacturing (KAM) has installed two more large format printers from EOS. With the addition of the two M400-4 Metal SystemsKAM now offers five large-format EOS systems, in addition to 15 others, for a total of 20 3D printers installed in its North Carolina factory, in addition to 12 multi-axis CNC machine tools.

“One of the biggest challenges in our industry is building end-user confidence in the manufacturing supply chain. The rapid growth in the volume and size of additively manufactured parts must be met with a corresponding increase machine bandwidth, material availability and finishing capability,” explained Brad Keselowski, owner and founder of KAM. “It is essential to respond to this development and today we are adding two more large platform EOS M400-4 printers. Installing the machine today demonstrates KAM’s commitment to keeping pace with the AM industry and the needs of our customers. »

Divergent Technologies signs an SLA for SLM Solutions’ NXG XII 600 fleet

Divergent Technologies and TDM solutions have a joint development partnership since 2017, working together to advance cost-effective mass production of complex 3D printed structures in automotive and defense applications. To secure its AM-based business model and resulting production, Divergent has now signed a long-term service level agreement (SLA) for the entire SLM NXG XII 600 printer fleet. This means that by the end of 2022, an installed base of six of these 12-laser systems will meet the mass production requirements of the Divergent Adaptive Production System ( DAPS), the company’s end-to-end digital production system. SLM Solutions has defined a new type of SLA based not only on the secure technical availability of its NXG XII 600 printers, but also on the portfolio of residual machines. This availability-based agreement covers all six NXG XII 600 assets, with a dedicated field service engineer on site.

“The NXG XII 600 is designed for mass production of very complex applications as well as for printing large parts,” said Gerhard Bierleutgeb, COO of SLM Solutions. “Therefore, it is of the utmost importance to provide our customer base with a top-notch service commitment to enable them to facilitate the machine according to their needs. No idle printers here.

The Barnes Global Advisors team welcomes two new members

LR: Andy Davis, Ethan Clare

Barnes Global Advisors (TBGA), the largest independent AM engineering consultancy, has Welcomed two defense and advanced manufacturing industry veterans to its ADDvisor team. Andy Davis, most recently Deputy Program Director and Director of Technology for the Industrial Base Analysis and Sustainment (IBAS) Program in the Office of the Secretary of Defense, fills the new role of Director of Government Programs of TBGA. A founding member of the U.S. Army AM Community of Practice, Davis will lead strategy and execution as the consultancy supports government clients with growing defense industrial base resiliency. Ethan Clare, who joins TBGA as project manager, previously held a senior position at Lockheed Martin Skunk Works to drive advanced manufacturing in production programs, and most recently worked at nTopology. He will focus on the effective execution of advanced manufacturing, government programs and supply chain optimization.

“These additions to the TBGA team will drive our continued growth in advanced manufacturing by supporting public and private customers through strategy, workforce development and qualification,” said John E. Barnes. , founder and CEO of TBGA. “We are proud that these efforts are supporting economic growth by restoring our domestic manufacturing capacity and improving domestic supply chain resilience.

3D Printed Lithophanes for Visually Impaired Chemists

A team of American researchers, led by Baylor University biochemist Bryan Shaw, enables blind and visually impaired chemists to “see” scientific images and graphics. As they explain in a research paperthe team used 3D printing to convert maps and images into lithophanes, which present this high-resolution data in a tactile way. Shaw’s son has tumors in both eyes, and although he can still see well, many of his friends can’t see him, causing Shaw to think about how to make science more accessible. Starting by converting images into tactile graphics using a home 3D printer, he eventually involved his students as well, and they moved on to 3D printing lithophanes of textbook illustrations, protein electropherograms on gel, micrographs of a butterfly chitin scale, and more. Then they compared how groups of sighted, blindfolded, and visually impaired students and researchers could interpret the data, and on the majority of questions, the blind chemists scored at least as well as the sighted. using 3D printed lithophanes. . Shaw hopes to improve the technology so visually impaired researchers can print the lithophanes themselves directly from journal articles, but this is a great first step.

“When I started in chemistry, I was actually strongly discouraged from doing it precisely because the instructor felt there was no way to understand the pictures he was drawing on the board,” said Matthew Guberman-Pfeffer, a chemist at Yale University. has been functionally blind since birth. “Now one thing lithophanes allow an instructor to do is sketch out their course and then 3D print it – problem solved.”

Youngstown Business Incubator Acquires XJet Ceramic 3D Printer

Northeastern Ohio and ceramic making have long gone hand in hand, but in the traditional sense. Today, the Youngstown business incubator (YBI) modernizes this tradition by to acquire a XJet Carmel 1400C ceramic 3D printer. Used to make small ceramic parts that are nearly impossible to make with traditional technologies, it is the first such printer available for public use in the United States. she sees this emerging technology as an asset for companies in the city, which can now use the incubator to print ceramic parts. According to an Israel-based XJet delegation, the Carmel 1400C can provide excellent geometry and production materials at no “additional cost”. The system works by suspending the ceramic material in a liquid and printing one layer at a time, each about a quarter of the width of a single strand of hair.

“You print the real material. The software will put another material which is a placeholder,” Danai said. “At the end of the print, you put it in water and the water will melt.”
