What Is Selective Laser Sintering?

Selective Laser Sintering (SLS) is a powder-based 3D printing method where a laser selectively fuses material layers to form a complete part. The laser outlines the cross-sectional pattern of a 3D design onto a powder bed. Once a layer is completed, the platform descends, and another layer is added on top, repeating until the entire object is constructed.

SLS stands out for its applicability in functional scenarios, especially for parts with features like snap fits, living hinges, and various mechanical joints. The broad spectrum of materials and the size of platforms available make SLS an excellent choice for directly producing items that need to be strong and heat-resistant.

The table below depicts the general tolerances for industrial-grade SLS services. Stresses during the build, support strategy and other geometry considerations may cause deviation in tolerances and flatness. Improved tolerances may be possible with a manual quote review, after successful completion of a prototype build, and must be approved on a case-by-case basis.

SLS 3D printing finishing options

As-printed

The part is de-powdered and cleaned via air blasting, leaving a natural grainy texture. Depending on the material used, the finished product is typically white or black.

Short peening

The part is blasted with small spherical media, such as glass or plastic beads, at controlled velocities. The impact creates beneficial compressive stresses in the part and smooths the surface, enhancing mechanical properties and improving the finish.

Vibro polishing

Finished parts are placed in a vibrating container filled with polishing media, such as ceramic or plastic beads. The continuous vibration causes the media to gently abrade the parts’ surfaces, gradually reducing surface roughness and improving finish quality.

Dyeing

Parts are dyed by immersion in a warm color bath. The dye penetrates the part’s surface to a depth of 0.25 mm to 0.5 mm. Available colours include black, blue, red, green, and yellow.

Custom

You can specify custom finishes such as painting and electroplating. Note that custom finishes require manual review and quoting and may be subject to approval.
