Metal 3D Printing Service

Overview of the direct metal laser sintering (DMLS) process offered at GPI Prototype. Sometimes referred to as metal 3d printing or a metal 3d printer, DMLS uses a laser beam to melt 20-40 micron layers of metal powder on top of each other to create metal parts. This additive process is similar to 3d printing, although metal powder is spread across a build platform and melted instead of a plastic filament being extruded.

Parts created using DMLS are fully dense metal with excellent mechanical properties. Other metal 3d printing processes exist which use a binder, although they produce parts which are not fully dense metal. The DMLS process can produce complex geometries which traditional cnc machining processes are not capable of.

3DMT specializes in metal additive manufacturing and the key component of the technology is material. With a long history of powder metallurgy in ARC Group, this experience transfers to 3DMT with metallurgists on staff, on-site material testing capabilities and heat treatment knowledge.
