3D AMUG and RAPID + TCT
H13 tool steel. Together, these studies underscore the benefits of Mantle’s True- Shape technology, according to company officials, in quickly printing precision components for prototype and production tools, molds, and dies—and advancing from designs to molded parts in weeks.
Mantle’s hybrid technology, additive and subtractive machining with sintering, works together with its proprietary Flow- able Metal Paste in creating high-precision inserts. This singular application focus on toolmaking solutions enables Mantle to optimize the value of its technology for toolmakers, company officials report.
For example, earlier this year Mantle teamed with Westminster Tool, Plainfield, CT, to help produce tooling inserts to enable quick molding of medical forceps sample parts. Westminster Tool wanted to mold the forceps from a highly glass- filled, bio-based PA11 that is focused on surgical-device applications. According to Eddie Graff, Westminster Tool manu- facturing engineer, a traditional aluminum prototype tool would present difficulties in molding the material. Mantle provided a solution.
Graff designed the tool inserts to include conformal cooling channels.
“These are more effective at control- ling the cavity temperature, which is crit- ical to molding this particular material,” he says. Mantle then printed the inserts in 86 hr. “In the end,” Graff offers, “it took us three weeks to go from design to FOT, quality medical parts on a prototype tool.”
Mantle’s metal-AM inserts (pictured) held a tolerance of ±0.0015, and because they were made with H13 steel, they allowed Westminster to add a subgate to allow molding of thousands of parts with- out the risk of gate erosion.

EOS North America to Open SoCal AM Innovation Center This Fall
Heading into RAPID + TCT, EOS North America announced plans to open an AM Innovation Center this fall in the Los Ange- les/Long Beach area of Southern Califor- nia, dedicated to AM training, engineering and customer support. The regional center is part of a $15 million-plus investment by EOS North America to support aero- space, space, medical and consumer goods markets.
The new center will support EOS cus- tomers through a team of application engineers and service technicians, and other customer-support resources, and will serve as a hub featuring some of EOS’ latest metal and polymer 3D printing tech- nology, including customized machines from AMCM and pre-release systems and software, according to company officials.
“The SoCal area is a hotbed for several flourishing industries that rely on our technology for their 3D-printed applica- tions,“ says Glynn Fletcher, EOS North America president. "We recognize the importance of working very closely with these key customers and will now be posi- tioned right on their doorstep.”
Customer training and education, application development, benchmark builds, and production strategy will be the focus of the new EOS Innovation Center.
“Innovation does not come from tech- nology alone; it comes from learning how to successfully apply it,“ says Dr. Gregory Hayes, EOS North America senior vice president of applied engineering. “The new LA-area facility brings all of the nec- essary elements into the region, making it easier to help our customers achieve their goals and grow their AM programs.” EOS: www.eos.info 3DMP
