What is SLS printing?

Selective Laser Sintering(SLS) is an industrial 3D printing process that is excellent for making end-use parts. In SLS, a laser selectively sinters polymer powder fragments, fusing them and building a component layer-by-layer. With some of the largest print beds, SLS machines can produce useful plastic to get rid of isotropic mechanical homes for thorough prototyping or low-volume production of end-use parts. SLS is an inexpensive production technique, which our customers consistently pick for the most complex parts and those calling for considerable modification.


SLS 3D Printing Materials

3d printing prototypes


White, dyed black. Prototypes, detailed and complex parts, fully functional models, and end products.

PA12 glass filled

Off-white.Enclosures and housings, jigs, fixtures, tooling

SLS 3D Printing Finishes

As Printed

Generally white or rock gray, smooth surface area, powder texture, without noticeable layers.

Dyed (black)

Dyed black by immersion in a warm color bath. The color penetration reaches a depth of about 0.5 mm and covers all surfaces.

SLS 3D Printing Advantages And Drawbacks



SLS 3D Printing Application

Concept Models

The rate and adaptability of SLS printing let product designers create physical pictures of their layouts with the iterative procedure.

Rapid Prototyping

SLS prototyping can be made use of to develop completely functional prototypes, full of relocating parts, as well as all-in-one settings up.

Direct Digital Manufacturing

The high accuracy and consistency of SLS make it an ideal way to build large quantities of discrete or customized parts.

SLS 3D Printing FAQs

SLS is a great solution for the rapid prototyping of functional polymers because it offers a very high degree of design freedom and high accuracy. And unlike FDM or SLA 3D printing techniques, it produces parts with consistent mechanical properties. This means it can be leveraged to produce parts that are very close to end-use part quality, so you can rely on the technology for concept to trial models.

Its versatility makes SLS 3D printing an ideal alternative to injection molding for low-production runs. SLS can be used to manufacture parts with complex shapes and geometries, and with a wide variety of finishes and lead times.
