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
We can quickly produce both prototypes and large batches thanks to the largest manufacturing network in Europe, with over 2,000 vetted partners
You will get your 3D printing fast delivered in as fast as 3-5 days.
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
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.
- Nylon 11
- Nylon 12
- Nylon 12 (Glass-Filled)
- Flex TPU
- PP Polypropylene
- Aluminium-Filled Nylon (Alumide)
- Food-Grade Nylon
After the media-tumbling, parts will have smoothened print slice traces and less sharp edges. The parts are left with an eggshell finish.
- Dyeing: blue, red, black, green colours
- Spray paint colouring: any colour, just add this as a custom finishing option in the Instant Quoting Engine
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.
Pros & Cons of SLS 3D Printing
|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|
