SLS 3D Printing Capabilities
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 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.
- Lead time: 3 days
- Build volume: up to 340 x 340 x 605 mm (320 x 320 x 580 mm recommended)
- Layer thickness: ~0.1 mm and for water-tight parts 1.5 mm
- Minimum feature size: 0.5 mm
- Tolerance: ±0.3% (± 0.3 mm)
Try Xometry Out Now In Just A Few Steps
Multiple designs for different parts can be imported at the same time to produce a single quote. In less than a minute, a detailed cost estimation appears on the screen.
First, select the manufacturing process you require. You can then choose from over 70 materials, both metals and plastics, and from a wide range of finishes and certifications.
Once you have selected the required options, all you need to do is confirm the order and pay for it on the secure payment platform. Your design will be analysed by engineers.
Within a short amount of time, you will receive the parts you ordered directly to your shipping address. You can track your package at any time in your personal account.

SLS Materials for Special Applications
Food-Grade
Food-grade PA 11 and PA 12 are highly regarded food-compliant materials that have gained popularity along with SLS 3D printing. These materials possess exceptional biocompatibility and are specifically formulated to meet the stringent requirements for producing food-related objects.
Xometry offers two food-compliant materials compatible with SLS:
- PA 12 – in white colour
- PA 11 – in blue colour
Flame-Retardant
PA 2241 FR is a polyamide powder infused with a concentrated flame-retardant compound. This high-performance material proves to be highly advantageous when it comes to producing flame-resistant components possessing remarkable mechanical characteristics. This material is hence suitable for aeronautics and aerospace applications.
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 |
