Selective laser sintering (SLS) is also known as the powder bed fusion process. SLS systems print thermoplastic polymer materials, polymer composites, or in some cases ceramics.

SLS processes begin by spreading a thin layer of powder across the build platform. Then cross-sections are melted layer by layer at a time, mostly using a laser beam, electron beam, or intense infrared lamps

Success with SLS starts with parts optimized for the printing process. The following guide captures the important design factors that are generally applied during designing parts for SLS.

Supported wall thickness

Supported walls are joined with other walls or shapes on at least two sides. The minimum vertical wall thickness of 0.6 mm. The minimum horizontal wall thickness of 0.3 mm
