Selective Laser Sintering (SLS) 3D Printing

General Purpose Prototypes & Production Parts

Ultra durable, accurate & functional parts with excellent throughput. Ideal for high volume production.

What is Selective Laser Sintering (SLS)?

Selective Laser Sintering (SLS) is an industrial additive manufacturing process that fuses together powdered thermoplastic polymers using a high powered laser. The laser selectively sinters the particles of the powder and binds it together to create a solid structure, layer by layer. SLS offers fantastic part throughput with its unique ability to nest thousands of parts within the boundaries of the machine without the need for support structures. This allows it to be used not only for rapid prototyping, but also for high volume manufacturing of end-use parts. SLS offers 5 high performance 3D printed materials that offer durability, electric static dissipation, temperature resistance, USP Class VI Biocompatibility, and/or Flame, Smoke Toxicity (FST) UL-94 ratings.

Manufacturing using Selective Laser Sintering 3D printing services is ideal for producing parts that look, feel and perform like end-use parts. They offer a uniform matte finish with little to no visible layer lines. Functionally they perform exceptionally well in demanding applications, offering consistent mechanical properties, abrasion resistance and excellent impact resistance. This makes SLS 3D printing a great substitute for injection molding or functional rapid prototyping at low to mid sized production volumes.

Design Guidelines | Selective Laser Sintering

Selective Laser Sintering (SLS) is an additive manufacturing process that uses powdered thermoplastic polymers. This design guidelines covers specific design parameters, which will need to be followed to prevent build failures from occurring. We have set minimum allowed tolerances to ensure your parts are built successfully and perform to the the highest standards of the technology.

Accuracy

Layers are fused together using a laser that selectively scans and hardens the fine particles of powder to create a solid structure. The machine begins sintering at the bottom of the powder bed, building up each cross section by the set layer height of 60-100 um. Parts are typically produced within +/- 0.25mm for most geometries.

Surface Finish

Parts produced using SLS provide a uniform finish with excellent mechanical properties and abrasion resistance, making it a suitable substitute for injection molding as well as functional prototyping alike. We also offer in-house dying and painting services to take your parts to the next level.

Pricing

Optimizing your designs for Selective Laser Sintering will help keep manufacturing costs down. Price is primarily based upon the X, Y, & Z extents of your part. Small, dense parts are priced the most competitively in this technology. Wall thickness has less of effect on the cost of manufacturing your part than the overall size of it.

Build Size

Our SLS machines by EOS have a building volume of: 700 mm x 380 mm x 580 mm (27.6 x 15 x 22.9 in.), a standard layer thickness of 100 um, and a laser diameter of 0.4mm with a laser offset of 0.25mm. SLS offers excellent part accuracy and repeatability with most parts being within +/- 0.25mm. Tighter tolerances are achievable upon request.

Minimum Wall Thickness
