Metal Additive Manufacturing
WHAT IS LASER POWDER BED FUSION?
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) technology that uses a laser to locally melt metal powder in a layer-by-layer fashion according to a user-supplied CAD model. The final product is a three-dimensional part intended to replicate the user-supplied CAD (Computer-aided design) geometry.

Lockheed-Martin -
Essentially, any weldable metal can be printed using this machine, including steel, nickel, titanium, and aluminum alloys.
-
Spatial resolution is governed largely by minimum build layer thickness: 10 μm.
-
The print time depends on the part size, geometry, and laser settings. Time can range from several hours to more than a day.
-
Geometries that are too complex or too intricate to be manufactured using conventional manufacturing techniques are ideally suited for LPBF.
-
This machine has an open architecture, meaning that the operator has nearly complete control over the process settings.
