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 PA 12

Tough & Durable parts for Prototyping & Production

PA 12 is a highly functional polyamide material that provides a consistent surface finish, with excellent resolution and feature detail. Duraform PA is ideal for both functional prototyping as well as end use applications that require complex thin wall parts, chemical resistance, snap fits and/or low vibration resistance.

Advantages

  • Durable

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

  • Production Quantities

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

  • Accurate

    Ideal for thin wall parts, SLS is uniquely 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 | Selective Laser Sintering

  • Minimum Wall Thickness

.8 mm

  • Minimum Detail Size

0.7 mm

  • Tolerances

±0.3 mm plus ±0.002 mm/mm

  • Minimum Hole Size

1.5 mm

  • Minimum Drain Hole Size

3.5 mm in diameter

  • Minimum Text Size

2 mm

  • Layer Height

100 μm

  • Maximum Build Size

550 x 550 x 460 mm (22 x 22 x 18 in.)

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