Part Cleaning Issues

# Issue Description Customer Troubleshooting Steps
PCI1 Parts come out of cleaning process dirty, shiny, or sticky.
  1. Parts may not have been properly cleaned. Ensure you have followed all the steps in the sections under Cleaning Printed Parts.
  2. Parts may not have been cleaned soon enough after printing. Be sure to clean your printed parts within 24 hours of the print job finishing.
  3. Solvent baths may need to be changed.
PCI2 Parts show surface cracks or edge erosion during sonication cleaning.

Your particular print material may be sensitive to sonication power. Reduce the power of your ultrasonic cleaner; reduce the duration of sonication; or, reduce the temperature of the cleaner's tank.

PCI3 Parts crack downstream after post curing.
  1. Parts may have been overexposed to solvents during cleaning. Ensure that you clean printed parts no longer than the times specified in the section Cleaning Parts Using an Ultrasonic Cleaner.
  2. If your cleaning times were correct, there are other cleaning parameters that you can try changing:
    1. Reduce sonication power.
    2. If your ultrasonic cleaner's power setting cannot be changed, reduce cleaning time.
    3. Reduce temperature of liquid in ultrasonic cleaner.
    4. Increase drying time after cleaning.
PCI4 Supporting architecture not completely removed by hand
  1. Ensure that for future builds, you have removed the supporting architecture before post-curing the part(s). The post-curing process makes the supports stronger and, therefore, harder to remove.
  2. Use tools such as flat snips and/or tweezers to remove support remnants from tight areas of your part.
  3. Perform wet-sanding with >90% alcohol solvent on support remnants.
