Shavings on Model or Tray
Shavings on Model or on Tray
Sometimes, shavings of cured material appear on the model’s surface or around it.
Possible Causes and Solutions
Roller Waste Collector Overflow
The roller waste collector can overflow with cured material residue if it is not emptied frequently enough. Particles of this residue can appear on the model’s surface, looking like shavings that started to peel off during printing.
Solution: Clean the roller waste collector once a week to prevent this effect. See the user guide for instructions.
Preventive measures: Same as solution.
Dulled or Misaligned Roller Scraper
The roller scraper may be dull or misaligned, and therefore, not properly removing excess material from the roller. If the roller is not clean, surface quality can be affected.
Solution: Replace the roller scraper. If you are using one of our desktop printers, replace the roller waste collector assembly. See the user guide for instructions.
Preventive measures: Run the Cleaning wizard before and after every print job. Make sure to clean properly between prints and maintain the printer properly.
Also, periodically test the effectiveness of the roller scraper when you clean the roller waste collector. Replace the roller scraper blade after 1,000 hours of printing or if it does not effectively keep the roller clean, whichever comes first.
