Description:

Nylon 12 Powder, also known as PA 12 (SLS), is engineered for functional prototyping and end-use production of strong, detailed, and complex parts. It offers high-density structures, excellent tensile strength, ductility, and chemical resistance to oils, greases, hydrocarbons, and alkalies. Ideal for complex assemblies and watertight applications, this robust thermoplastic minimizes water absorption and ensures durability and environmental stability, making it suitable for diverse environments. The properties of this material can vary based on the selected manufacturing process.

Bead blasting

Depowdering of parts with bead blasting. The final parts are slightly grainy in the touch with a satin-like matte appearance.

Notes:

Semi-sintered surface particles remain on the part even after initial depowdering.
Final result:
- Slightly grainy in the touch
- Satin-like matte appearence

Media tumbling

This is a batch-based process that tumbles vibrating media to remove sharp edges and burrs on machined parts. Tumbling can remove machine marks on exterior surfaces creating a more uniform appearance.

Notes:

Parts over 20 cm (8”) may require a manual review.
Final result:
- Smooth in the touch
- Satin-like matte appearance
Vapor Smoothing

Bathing printed parts in vaporized chemical solvents to create a controlled chemical melt of the material.
Notes:
Can soften sharp edges

Not suitable for small features and thin walls
Final result:
- Smooth in the touch
- Glossy appearance

Spray painting

Provides a continuous, protective color finish which is applied by spraying.
Notes:
Paint coating is just on the surface level, if it is scratched or subjected to wear and tear, the internal natural colour is visible

Possibility of requesting custom colours (RAL)
Available colors:
- Any custom RAL colour
Custom Finishing

If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.

Notes:
