WHAT IS A
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.

Frequently Asked Questions
Essentially, any weldable metal can be printed using this machine, including steel, nickel, titanium, and aluminum alloys.
The size of a printed part is limited by dimensions of the build space: Ø 170 mm (6.6”) x H 200 mm (7.9”).
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.
This machine has an open architecture, meaning that the operator has nearly complete control over the process settings.
Geometries that are too complex or too intricate to be manufactured using conventional manufacturing techniques are ideally suited for LPBF.
