SLS 3D Printing Services

Selective Laser Sintering (SLS) is one of the most popular 3D printing technologies that produces highly accurate and durable parts that are perfect for end-use, low-to-mid volume production, or for rapid prototyping.

Though SLS provides high detail quality and perfect production repeatability, it is one of the most inexpensive options for industrial 3D printing services because it can build parts in bulk without support structure requirements. SLS 3D printed parts can be post-processed by media tumbling and colouring.

Quality Assurance

Quality Assurance

We have strong QA procedures, controlled by an in-house team of QA engineers, which allows us to deliver high quality parts.

Engineering Check & Status Updates

Engineering Check & Status Updates

All designs are checked by engineers before they’re sent for 3D printing. After confirming your order, you will receive status updates on your production.

SLS 3D Printing Materials

  • Nylon 11
  • Nylon 11 Food Grade
  • Nylon 12
  • Nylon 12 Alumide Grey
  • Nylon 12 Food Grade Whitish
  • Nylon 12 Glass-Filled
  • Flex Whitish TPU/TPE
  • PP Polypropylene

Finishing Options


After the media-tumbling, parts will have smoothened print slice traces and less sharp edges. The parts are left with an eggshell finish.

Dyeing & Colouring
  • Dyeing: blue, red, black, green colours
  • Spray paint colouring: any colour, just add this as a custom finishing option in the Instant Quoting Engine
Food Grade Finishing

This finishing option assures its compliance with ISO 9001 Food Grade, and, as the result, these 3D prints can contact with food products. It is applicable with Nylon 12.

Bead Blasting

This process removes surface deposits by applying fine glass beads, without damaging the surface of the printed part.

Pros & Cons of SLS 3D Printing

Advantages Considerations
Free form design: doesn’t need support features Limited material and colour choice
Versatile, durable, flexible and chemical resistant material (Nylon) Surface roughness (however, could be reduced by media tumbling)
Scalable into series Warping issues for large feature
Fast: Xometry can deliver them in just 3 days Limited post-processing options
Cheap, especially for small series
