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, powder cartridge, and leveling roller. A thin layer of build material is spread across the platform where the laser traces a two-dimensional cross section of the part, sintering the material together. The platform then descends a layer thickness and the 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 the 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.
  • Maximum dimension for instant quote: 28”x19”x19”. Parts with larger dimensions are also available. Please contact your sales manager to discuss.
  • SLS Material choices include: Nylon (Duraform PA), Glass-Filled Nylon (Duraform GF), Flame Retardant Nylon and Durable Nylon (Duraform EX).
  • Standard Tolerances: of +/- 0.005" for the first inch, and +/- 0.003" for each additional inch.
  • In the z height (vertical), standard tolerances of +/- 0.01" for the first inch, +/- 0.003” on every inch thereafter.
  • Layer Thickness: 0.004".
  • Good Choice for high-heat and chemically resistant applications.
  • Lead Time Options: Next-day Delivery, Standard, and Economy.
