UPDATE - ARC Group Worldwide Further Expands Metal 3D Printing

DELAND, FL--(Marketwired - July 13, 2015) - ARC Group Worldwide, Inc. (NASDAQ: ARCW) (the "Company" or "ARC"), a leading global provider of advanced manufacturing and 3D printing solutions, today announced that its 3D printing/additive manufacturing division, 3D Material Technologies, LLC ("3DMT"), recently purchased additional metal 3D printing machines, including a Concept Laser M2 Cusing 400W Dual Laser printer and an EOSINT M280 printer. These new printers will further enhance 3DMT's metal 3D printing capabilities, one of the fastest growing segments within the Advanced Manufacturing sector.

3DMT acquired these new machines due to recent increases in business levels, thereby creating capacity constraints with its existing metal 3D printers, as well as expected growing demand for higher production volumes and shorter lead times. These new machines will add to 3DMT's already significant metal 3D printing experience and capacity, as well as its leading plastic 3D printing capabilities.

In particular, the new Concept M2 metal 3D printer further allows 3DMT the ability to pioneer material development and increase efficiency. The M2 utilizes dual lasers and varioscan optics, which greatly increase machine productivity and speed.

"We have recently experienced increased demand for our Additive Metal/3D printing services from the Aerospace industry, Department of Energy, Department of Defense, and Medical Device markets, which led us to purchase these new machines. Further, with production jobs from our existing customers tying up significant existing capacity, the additional equipment allows us to continue to use our expertise in powder metals to increase capacity and develop new materials not currently being offered," stated Ashley Nichols, General Manager of 3DMT. "Notably, we will be working on new aluminum alloys, as well as high strength, high temperature ferrous alloys, which are of great interest to our customers. We have been quite encouraged by this recent increase in adoption of metal 3D printing by clients who traditionally used legacy manufacturing processes, and believe this is potentially indicative of the future market opportunity that additive metals may have."

Overall, these additional machines will significantly increase 3DMT's capacity and reduce lead time to support customers in the aerospace, defense, dental, and medical industries, as well as in ARC's metal injection molding, injection molding, tooling, and various capabilities. Further, these new machines have the capability of making a wide variety of parts out of Inconel 625, Inconel 718, titanium, aluminum, stainless steel, cobalt chrome, and maraging steel.
