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.

Finishing Options for SLS 3D Printing
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 |
