What is SLS Printing?

The following is an excerpt of a knowledge article written for PrototypeHubs.com. To read the full article, click the link at the bottom of the page.

Selective Laser Sintering (SLS) is an Additive Manufacturing (AM) process that uses laser power to sinter powdered material, typically plastics, into a solid 3D model. Sintering—using atomic diffusion to create objects from powdered material—has been around for thousands of years. However, it was first developed as an AM technique in the 1980s at the University of Texas at Austin and has been used as a foundation to develop similar processes for metals, glass, ceramics, and some composites. Although desktop and hobby 3D printers are widely available, there are very few SLS versions due to the complexity of the process.

The main benefit of SLS over other AM processes (such as Stereolithography (SLA), Fused Deposition Modelling (FDM), or Fused Filament Fabrication (FFF)) is the unfused powder acting as a self- supporting material…
