Smooth

PA 12

  • Loose powder removed
  • Sandblasted
  • Smoothed: Your part is mechanically polished by being put into a tumbler with pebbles that smooth your part while the tumbler vibrates at a high frequency.
    • We can only smoothen the A-side (the outside of your part), it’s not possible to completely polish the inside
    • The polishing process will take 0.1 mm of material off your part, so add extra wall thickness to avoid any 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 polished
    • The process is limited to parts ranging from ±30 to 200 mm
