Selective Laser Sintering (SLS)

Selective laser sintering (SLS) uses a laser to solidify, or sinter, powdered nylon into cross sections. Guided by a 3D model, SLS sinters layer upon layer until the product is complete. 3D printed nylon products created with SLS are lightweight and durable, able to be made hard, tough or flexible as needed. The plastics used in SLS are food safe and do not leach. With a relatively large bed, SLS is a well-suited to 3D printing a large volume of plastic parts in single runs.

3D printed plastics are durable, inexpensive and quick to produce. They also eliminate many of the design restrictions of traditional manufacturing. To learn more about our other 3D printed plastic options, check out our HP Multi Jet Fusion 3D printing services or our 5-Minute Buyer’s Guide.

*Build volume is up to 27.6 x 15 x 22.9 inches. Larger models can be made in sections and pieced together after printing.

**Large SLS parts can be prone to warp, which explains the scaling tolerance. Minimum tolerances are +/- 0.010.
