Selective Laser Sintering converts CAD data into two-dimensional cross-sections or layers that are each sintered together on a platform as an additive process. The process is fast and parts can be nested to maximize economy, delivering a service far superior to those relying on traditional prototyping or pattern cutting processes.
The SLS process allows us the ability 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 Product Development an additional avenue for generating patterns and prototypes.
SLS Highlights
Selective Laser Sintering (SLS) is the ideal choice for:
Prototypes that require material properties which closely replicate those of injection-molded parts.
Material choices include:
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. Turnaround for hand-held parts is typically 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:
- 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.
