Selective Laser Sintering (SLS)


tic prototypes and Parts Direct from CAD.

Selective Laser Sintering (SLS) is an additive manufacturing technology. This process uses high power laser to fuse small particles of plastic, metal, ceramic, and glass powder directly from computer-aided design (CAD) data into a three dimensional shape.

As each cross-section is scanned, the powder bed is lowered by one layer thickness, scanning and sintering one layer at a time until the build is complete.

Part tolerances typically measure 0.004”- 0.008 overall.


  • High accuracy
  • Tool less production
  • Wide range of materials offered
  • Multiple finishing options
  • High heat deflection temperatures


SLS technology is widely used in many industries due to its ability to easily make complex geometries with little to no added manufacturing effort. Its most common application is in prototype parts early in the design cycle, such as investment casting patterns, automotive hardware, and wind tunnel models. SLS is also increasingly being used in limited-run manufacturing to produce end-user parts for aerospace, military, medical, and electronics hardware.


At Fusion PM, the technology offers numerous advantages to our clients, rapidly delivering plastic prototypes and parts via additive manufacturing in as little as 2 to 3 days.

The Fusion PM team has over 10 years of experience working with SLS materials and processes

We have a good range of materials for this technology, learn more here.
