Laser Sintering Design Guidelines

Laser Sintering (also known as Selective Laser Sintering, SLS, or LS) is an additive manufacturing process that builds parts by using a laser to selectively sinter (heat and fuse) a powdered material.

The process begins with a 3D CAD file, which is mathematically sliced into 2D cross sections. With the build piston at the top of the build volume, a roller assembly pushes build material from the powder supply to create a uniform layer over the build piston. The scanning system then draws the 2D cross section on the surface of the build material, sintering the material. The build piston is lowered as the powder delivery piston is raised and a new layer of material is placed in the build volume. The next 2D cross section is drawn and the process repeats itself until the object is complete.
