Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) is the ideal choice for:

  • Prototypes that require material properties that closely replicate injection-molded parts.

Material choices include:

Additional SLS Technical Data:

Dimensional tolerances:

  • +/- 0.007” Depending on material

Layer thickness:

  • 0.004” – 0.006”

Build envelope:

  • 22” x 22” x 30”

Delivery:

  • Depending on size of the part. Typical Turnaround for hand-held parts is 2 to 3 days

Wax patterns:

  • Castform PS material is similar to foundry wax. SLS patterns made from this material are used in the investment casting process.

Finishing Types:

  • 2A: Parts are cleaned and a bead blast applied to eliminate rough spots and remove all excess powder.
  • 3A: After application of 2A finish, parts are lightly sanded and sealed with a water resistant liquid sealer creating a water proof part with smooth finish.
  • 3A Paint Ready: 3A finished part is sanded and a coat of primer is applied to create a smooth finish ready for application of paint and texture.

Selective Laser Sintering (SLS)

An additive rapid prototyping process, Selective Laser Sintering (SLS) builds 3-dimensional parts from CAD data from a range of powdered materials like polyamides, nylons, or metals. Then a laser beam selectively heats and fuses (sinters) two-dimensional cross-sections or layers as an additive process. SLS provides a fast and easy way to create parts early in the design cycle, but is also suitable for limited production runs.
The SLS process is fast and parts can be nested to maximize economy, delivering a service far superior to traditional rapid prototyping or pattern cutting processes.

The SLS process allows us to build parts in both engineering type resins as well as disposable foundry waxes. The ability to produce a variety of parts quickly and accurately has given our customers a dramatic advantage in new product cycle times and overall time-to-market.

The latest generation of Selective Laser Sintering machines has given 3D-CAM an additional capability for generating patterns and prototypes.
