SLS 3D Printing Service
Selective Laser Sintering is a 3D printing process that produces a highly precise and accurate part. It can be used for a variety of industries, including automotive, aerospace, and medical.
What is SLS 3D printing?
SLS 3D printing is perfect for parts that need to be precise and accurate, while maintaining strength and durability properties. It is available for our nylon and polyurethane materials.
The process of SLS printing involves layering a polymer powder and solidifying it with a laser and binding agent. The part is them built up layer-by-layer until the final product is completed.
SLS is a cost-effective production method. It is capable of producing large parts and parts with complex geometries.

Post-processing for SLS
We offer multiple finishing options for SLS printed pieces.
Raw- No finish applied, as machined
Polished- Part is tumbled and then shot-peened, resulting in a very smooth surface
Vapor polished- Part is sealed in a chamber and coated with acetone vapor to smooth surface, resulting in a polished surface
You can also have your SLS parts dyed to any color you like by selecting the color in our quote engine.

Why should you choose SLS 3D printing?
SLS printing is a great option for any project. It can be done with materials that are exceptionally strong or that are capable of producing a flexible part, depending on your needs. It is also an environmentally-friendly manufacturing process.
We have high standards for SLS 3D printing
With JawsTec, every order is backed by our quality assurance policy. Each part will meet your standards and fulfil the needs of your project.

Advantages and drawbacks of SLS 3D printing
Advantages
- Superior strength of structures and geometries
- High precision of parts
- Design guidelines allow for highly customized designs
- No supports needed for printing
Drawbacks
- PA12 material can result in surface defects due to its recyclable nature
- Slightly more expensive than other printing processes
- Occasional longer lead-time as opposed to other materials
Designing files for SLS printing
There are a number of rules you will want to keep in mind when designing your CAD files for SLS printing:
- Save cost and time by minimizing mass volume and wall thickness wherever possible
- Remember our tolerance guidelines, use symmetric design tolerances
- Rounded corners generally work better than sharp ones, saves material and improves flow of force
- Optimize parts for powder removal in post processing
- Design with a minimal loose connection distance of 0.1 mm
