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.

Advantages of SLS with Xometry

Massive Capacity

Massive Capacity

We can quickly produce both prototypes and large batches thanks to the largest manufacturing network in Europe, with over 2,000 vetted partners

Fast Production

Fast Production

You will get your 3D printing fast delivered in as fast as 3-5 days.

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 Materials

  • Nylon 11
  • Nylon 12
  • Nylon 12 (Glass-Filled)
  • Flex TPU
  • PP Polypropylene
  • Aluminium-Filled Nylon (Alumide)

Finishing Options

Media-Tumbling

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.
