Fast and Scalable

Selective Laser Sintering (SLS) is a powerful 3D printing technology that produces highly accurate and durable parts that are capable of being used directly in end-use, low-volume production.

Advantages of SLS

SLS 3D Printing lets you produce high-accuracy prototypes and end-use plastic parts at competitive prices. Since manufacturing
can be done directly from a 3D CAD file, SLS is considered a faster, more affordable alternative to injection molding.



We use the latest generation of SLS technologies to meet tolerances of +/- 0.005” or +/- 0.002” per inch, whichever is greater.


Built in nylon, a durable material with great impact strength, medium flexibility, and high resistance to environmental factors.


SLS can make a single part or component as easily as dozens of production pieces.


Complex Geometries

Geometries can be built more easily due to the 3D printing process, adding complexity without additional cost.

Rapid Turnaround

Parts can typically be shipped in 1-4 days, allowing for faster design iterations and speed to market.

Part Production

SLS is capable of producing end-use parts on-demand, increasing throughput.





Concept Models

The speed and versatility of SLS lets product developers create physical snapshots of their designs through the iterative process.

Rapid Prototyping

SLS can be used to create fully-functional prototypes, complete with moving parts, as well as all-in-one assemblies.

Direct Digital Manufacturing

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


Durable White Nylon

Material Details



SLS parts have all powder removed through bead blasting. Light sanding may be used to remove significant grow lines. These parts are left with a satin-like matte finish.


Xometry can provide additional processing (i.e., painting or sanding) to meet your needs.
