Selective Laser Sintering (SLS)

Durable Low Volume Production & Prototyping

Volume Production

Parts built in 2-5 Business Days

Selective Laser Sintering (SLS) is a powder-based 3D printing process that uses UV stable, laser-sintered powder to create durable, complex shapes, with no need for support.

SLS provides a consistent finish with quality and production efficiency. With the option to efficiently stack parts in the build tray for small to medium sized production runs and high-capacity batch manufacturing.

Nylon 12  (Duraform PA)

Tough & Durable for Low Volume Production 

SLS durable nylon material  provides excellent surface resolution and feature detail and is ideal for low volume manufacturing. Duraform PA is easily machinable and paintable to create demonstration parts.

  • Durable

    Create functional parts with consistent durability that are capable of being used in end-use, low-volume production at competitive prices.

  • Part Production

    The scability of SLS allows small production runs of end use parts with material properties similar to injection molded parts.

  • Accurate

    Durable yet more accurate than FDM, SLS is capable of replicating small features with crisp details and a consistent surface finish.

  • Large Builds

    Produce parts with build volumes up to 22″ x 22″ x 30″ to produce large, complex parts in a single build.

Design Guidelines

  • Minimum Wall Thickness


  • Minimum Detail Size

    0.7 mm

  • Minimum Text Size

    2 mm tall

  • Tolerences

    ±0.3% (with a lower limit of ±0.3 mm)

  • Minimum Hole Size

    1.5 mm in diameter

  • Minimum Drain Hole Size

    3.5 mm in diameter

  • Maximum Build Size

    650 x 330 x 560 mm

  • Layer Resolution

    0.1 mm

Note that the SLS process may cause surfaces to experience overgrowth of roughly .1mm, while diameters can experience overgrowth of roughly .5 mm.
