SLS 3D Printing

SLS 3D Printing Service

Selective Laser Sintering is an industrial-grade 3D printing process. This method is ideal for creating durable, accurate, and high-performance prints. Furthermore, this method can be used to produce detailed parts with complex geometry. As a result, it is ideal for a wide range of professional manufacturing applications. It was first developed by Dr. Carl Deckard and Dr. Joe Beaman at the University of Texas, Austin in 1988. Here are more details about our SLS 3D printing process.

The Process:

Selective laser sintering is a type of powder bed fusion (PBF) process in AM. The feedstock for SLS is in the form of fine powder. In the PBF process, the powder particles are contained in a powder bed. Then, it is melted/sintered together, using laser power to heat it at a temperature above/below the melting point of the material.

Sintering refers to the process of heating the powder at a temperature below the melting point of that material and fusing the particles together. The particles form bonds and form the solid model as the laser follows the path created by the CAD file.


SLS prints are extremely accurate representations of 3D CAD data. Prints are Isotropic with chemical resistance. Benefits include drastic overhangs, moving parts, interlocking pieces, and interior mechanisms. 

Prints can be either rigid or flexible. In either case, they are extremely durable. We created these 3D printed sneakers entirely out of flexible material.


SLS 3D prints have a porous surface. For prints requiring an extremely smooth finish, SLA may be a better option.
