Order SLS 3D Prints Online
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.
Available SLS 3D Printing Materials
- Nylon 11
- Nylon 12
- Nylon 12 (Glass-Filled)
- Flex TPU
- 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.
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 | |

Manufacturing Specifications
Build volume: up to 340 x 340 x 605 mm, but usually we recommend the maximum size of 320 x 320 x 580 mm.
For custom parts in Nylon PA12 we can offer up to X-675mm Y-366mm Z-545 mm sized 3D printing. Submit such designs for a manual RFQ.
Layer thickness: ~0.1 mm and for water-tight parts 1.5 mm, when wall thickness is higher.
Minimum feature size: min 0.5 mm, 0.75 is recommended
Tolerance: +-0.3% (min. 0.3 mm)
