Loud Fan Noise When Printing

A loud fan noise when your Glowforge starts printing can be caused by:

  • Debris or build-up in the air assist fan located on the back of the printer head
  • Debris or build up in the exhaust fan located in the back-left corner of your Glowforge

The good news is, there's a way to fix this! Please review the following articles to clean your fans:

  • Steps to clean your exhaust fan can be found near the bottom of the guide to Clean Your Glowforge
  • Steps to clean your Air Assist fan can be found here.
