Material
PA 11
Ideal for both series production and functional prototypes, PA 11 combines excellent mechanical properties with impressive surface quality and detail. Coupled with its suitability for moving features like snap fits, living hinges, and interlocking parts, this material offers great value to industries such as medtech, orthotics, prosthetics, automotive, and aerospace.

Finishing degrees
The right finish can transform your print into a product. Explore the post-production finishes we offer for this material. If you have any questions or special requests, get in touch with us.
Normal
- Loose powder removed
- Sandblasted
Smooth
- Loose powder removed
- Sandblasted
- Parts are mechanically polished by being placed in a tumbler, together with pebbles, which then vibrates at a high frequency.
- This process only smooths the A-side (i.e. the outside) of your part; it is not possible to completely polish the inside
- As the polishing process removes 0.1 mm of material from your part, you should add extra wall thickness to avoid problems
- Small details and thin walls could be worn away and may even disappear
- Edges will be rounded and your part will become less ‘crisp’ once tumbled
- This finish is only possible for parts ranging from ±30 mm to 200 mm
Color dyed
- Loose powder removed
- Sandblasted
- Parts color dyed by being submerged in a bath containing black pigment
- Color intensity may vary due to the unique nature of the production process, e.g. parameters, build position, light deflection, and differences caused by post-processing
- This finish is possible for parts with maximum dimensions of 360 x 274 x 375 mm
Smooth + color dyed

- Parts are color dyed by being submerged in a bath containing black pigment
- Color intensity may vary due to the unique nature of the production process, e.g. parameters, build position, light deflection, and differences caused by post-processing
- Colors will appear lighter than on parts that have not been tumbled
- Differences in smoothness (e.g. inside and inside of corners) may lead to some color variation
