PA 12 (SLS)
High mechanical and thermal resistance make laser sintered PA 12 (SLS) an ideal choice for a wide range of applications, from functional prototypes and end-use parts, to consumer goods. This material has excellent long-term stability, is resistant against most chemicals, can be made watertight by impregnation.

Finishing degrees

Normal
- Loose powder removed
- Sandblasted
- Fast Lane service available for online orders of PA 12 (SLS)
Sealing, standard
- Loose powder removed
- Sandblasted
- Treated with sealant that fills small pores
- Results in airtight/watertight parts
Extra smooth
- Loose powder removed
- Sandblasted
- Parts are chemically smoothed by being placed in a chamber with a vaporized solvent
- This process mainly smooths the outside of your part; the inside may be less smooth
- As the polishing process removes material from your part, you should foresee a minimum wall thickness of 2 mm
- Thinner walls (1 mm) could deform and small surface details may disappear
- Edges will be rounded and your part will become less ’crisp’ once smoothed
- Parts need to be hung up for this process; holes in the design can be used or a hook which is cut away after smoothing
- As residue from the smoothing process can accumulate in sharp inside corners (i.e. bridging effect), we advise adding chamfers to all corners
- The process is only available for parts with maximum dimensions of 560 x 360 x 330 mm
Color dyed
- Loose powder removed
- Sandblasted
- Parts are color dyed by being submerged in a bath containing color pigment
- Due to the unique nature of the laser sintering process, e.g. in terms of parameters, build position, and light deflection, color intensity may vary
- This finish is possible for parts with maximum dimensions of 400 x 330 x 360 mm (black) or 150 x 150 x 150 mm (other colors: brown, purple, blue, petrol, green, bordeaux, red, orange, yellow)
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 with maximum dimensions of 250 x 150 x 150 mm
Smooth + color dyed
- 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
- Parts are color dyed by being submerged in a bath containing color pigment
- Due to the unique nature of the laser sintering process, e.g. in terms of parameters, build position, and light deflection, color intensity may vary
- 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
- This finish is only possible for parts with maximum dimensions of 250 x 150 x 150 mm (black) or 150 x 150 x 150 mm (other colors)
