Metal 3D Printing


Sometimes referred to as metal 3d printing or a metal 3d printer, a laser beam is used to melt 20-40 micron layers of metal powder on top of each other to create metal parts. This additive process is similar to other polymer power bed fusion 3d printing processes, although metal powder is spread across a build platform and melted.

GPI currently has six metal 3d printers from EOS at our facility in Lake Bluff, IL. A variety of metal 3d printing materials are also available including stainless steel, cobalt chrome, maraging steel, aluminum, nickel alloy, and titanium.

Parts created 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 process can produce complex geometries which traditional cnc machining processes are not capable of.
