Last week I visited 3D Material Technologies, a new 3D printing service provider of ARC Group Worldwide (NASDAQ:ARCW).
There was an extensive use of robotics in their core metal injection molding operations, as well as a wide array of brand new 3D printers.
ARCW has a forward PE of 20 and grew net income by over 100% in the mrq.
