Polyamide 12 in laser sintering
SLS PA12 – durable functional parts in polyamide 12
PA12 3D printing for parts that have to hold: from a single piece to a series, without tooling. Made by us in Röslau, Germany, with over 170,000 parts so far.

The material
PA12: tough, dimensionally stable, versatile.
Polyamide 12 is the standard material for technical parts in laser sintering. It is tough, keeps its shape and suits many uses.
- Tough and dimensionally stable: good for housings, brackets and clips
- PA12 is known for good resistance to oils, greases and fuels. For special media, we are happy to clarify this with you beforehand.
- Across the layers, SLS parts are slightly weaker than within the layer plane. We discuss critical load directions before printing.
- White or black: we run a white and a black PA12 powder from Evonik. On request, we dye parts.
- PA11 on request
The process
Powder bed instead of support structures.
In laser sintering, a laser fuses the powder layer by layer. The surrounding powder supports the part, so printing needs no supports.
- Undercuts and internal geometries are possible
- Lattice and honeycomb structures save weight and material
- Snap hooks and film hinges can be printed directly (align the tongue within the layer plane)
- Several functions in one part instead of many separate parts
Series production
From a single part to a series, without tooling.
In the powder bed, many parts can be printed densely packed in one build job. That makes PA12 in SLS a series production process.
- No tooling or mold costs, economical from a quantity of 1
- Consistent quality: a mixing station keeps the ratio of new to used powder constant
- Reorders at any time from your CAD data
- Lead times from 3 days to 2 weeks, express by arrangement
Finishing
Depowdered, blasted and dyed.
Every part is depowdered and blasted in-house. On request, we dye it in the DeepDye process: the color sits in the material instead of lying on top as paint. Almost any RAL shade is possible on request.
Typical applications
What SLS PA12 is good for.
Wherever parts carry load, hold their shape and are needed in quantity.
Brackets & clips
Brackets, clips and snap hooks that can be printed directly. One part instead of an assembly.
Fixtures & grippers
Assembly aids, fixtures and grippers matched to your part. Quickly changed when your product changes.
Air ducts & channels
Air ducts, channels and cable holders with freely shaped paths, including internal ones.

FAQ
Frequently asked questions about SLS PA12
PA12 is tough and dimensionally stable, good for housings, brackets and functional parts. TPU is rubber-elastic, good for seals, dampers and grippers. More on the page SLS TPU A70.
We run a white and a black PA12 powder. On request, we dye parts in the DeepDye process, and almost any RAL shade is possible. The color sits in the material. More under dyeing SLS parts.
Not quite. Across the layers, SLS parts are slightly weaker than within the layer plane. For snap hooks, align the tongue within the layer plane. For critical loads, we are happy to discuss orientation before printing.
From a quantity of 1, since there are no tooling costs. For series, we pack many parts into one build job. Reorders run at any time from your CAD data. Whether an injection mold pays off is shown by the break-even calculator.
Typically between 3 days and 2 weeks, depending on quantity and workload. Express is possible by arrangement.
