Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) uses a laser to sinter powder based materials together, layer-by-layer, to form a solid model. The system consists of a laser, part chamber, and control system. The part chamber consists of a build platform, powdercartridge, and leveling roller. A thin layer of build material is spread across the plaform where the laser traces a two-dimentional cross section of the part sintering the material together. The platform then descends a layer thickness and leveling roller pushes material from the powder cartridge across the build platform, where the next cross section is sintered to the previous. This continues until the part is completed. Once the model is complete, it is removed from part chamber and finished by removing any loose material and smoothing the visible surfaces.

SLS Highlights

• Ideal for durable, functional parts with a variety of applications. Capable of producing snap fits and living hinges.
• SLS Material choices include Duraform, and DuraformGF.
• Standard Tolerances of +/- 0.005" for the first inch, and +/- 0.002" for each additional inch for Duraform and DuraformGF. For Somos 201, tolerances are +/- 0.04" for the first inch, +/- 0.002" on every inch thereafter.
• Standard Resolution: 0.004"
• Good choice for high-heat & chemically resistant applications.
• Samples available upon request.
