SLS (Selective Laser Sintering)

Selective Laser Sintering (SLS) creates tough and geometrically intricate components using a high-powered CO2 laser to fuse powdered thermoplastics. As a part is made, it remains encased in powder, creating a built-in support system. This eliminates the need for specific support structures and allows for complex geometries. SLS production parts can be strong, water and air-tight, heat resistant, and made out of a range of nylon options. SLS parts are ideal for functional testing, rapid prototyping, and additive manufactured parts, and are a great option for applications requiring a high heat or chemically resistant material.

Benefits: Durable and strong parts. Heat and chemically resistant.

Lead Time: Most SLS projects ship out in a standard lead time of 3 – 5 business days.

Tolerances: SLS prototypes can achieve tolerances of +/- .005” for the first inch, plus an additional +/- .002” for each additional inch.

Build Layer Thickness: SLS parts are typically built with a standard layer thickness of .004” - .005”.

Recommended Minimum Feature Size: SLS parts have a recommended minimum feature size of .030” - .035”.

Maximum single piece build size is 22" x 22" x 30" on our sPro 230 using Duraform Nylon materials.

Ideal uses for SLS:

  • Direct Digital Manufacturing (DDM)
  • High volume customized functional parts
  • Prototypes requiring high heat resistance
  • Under the hood automotive components
  • Living hinges & functional enclosures
  • Low volume rugged production parts
