LONGMONT, Colo., March 11, 2014 /PRNewswire/ -- ARC Group Worldwide, Inc. (NASDAQ: ARCW; the "Company" or "ARC") announced today that its division, 3D Material Technologies, LLC. ("3DMT"), purchased two Electro Optical Systems ("EOS") M 280 Direct Metal Laser Sintering (DMLS™) industrial 3D printers for the Company's Colorado production facility. The 3D printers have a build size of 250 x 250 x 325 mm (9.85 x 9.85 x 12.8 inches) and will increase 3DMT's capacity to manufacture complex parts out of stainless steel, maraging steel (MS1 material, tool steel), cobalt chrome, titanium, and aluminum. "EOS laser-sintering is a leading technology for aerospace and medical components, which make the 3D printers a strategic fit for our existing business. 3DMT provides engineering, prototyping, and short run production services in order to accelerate our customer's ability to access their respective markets as quickly and efficiently as possible," says Ashley Nichols, General Manager of 3DMT. Both EOS printers have been delivered, and 3DMT is already successfully printing metal parts. Notably, both EOS machines feature the 400 W laser upgrade. Benefits of the higher laser power include: (i) improved surface finishes for aluminum components; (ii) higher build speeds in numerous alloys, including a 190 percent increase in the build rate for MS1 maraging steel; (iii) an increased spectrum of available uses, including larger components such as molding tools requiring conformal cooling; and (iv) improved overall operational performance and reduced lead time. "Currently, the aerospace and medical industries are the strongest and fastest growing verticals for EOS laser-sintering solutions with DMLS parts in flight and 510K FDA-approved implants in the human body. We are excited to add 3DMT to our list of innovative customers acting as a service provider as we join to push design-driven manufacturing into the market," says Andy Snow, Director, EOS of North America, Inc. The addition of the two EOSINT M 280 DMLS systems expands 3DMT's already sizable 3D printing capabilities to sixteen industrial 3D metal and plastic printers, either in operation or on order, and further expands ARC's ability to offer rapid prototyping and short run production to its global customer base. 3DMT remains focused on bridging the gap between design concept and production through the use of advanced technologies and engineering knowhow.
