PA 12 (MJF)

• Loose powder removed 
• Sandblasted

• 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 

• Loose powder removed
• Sandblasted
• Parts color dyed by being submerged in a bath containing black pigment
  • Due to the unique nature of the production process, e.g. in terms of parameters, build position, and light deflection, as well as differences caused by post-processing, color intensity may vary
• This finish is possible for parts with maximum dimensions of 360 x 274 x 375 mm

• Parts are color dyed by being submerged in a bath containing black pigment
  • Due to the unique nature of the 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

• 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 (1mm) 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
• This finish is only possible for parts with maximum dimensions of 360 x 274 x 375 mm

Additional finishes are available on request:

• Color dyed + spray paint
• Extra smooth + color dyed
