Ultimaker Printer and Filament Compatibility Chart

Ultimaker printers are designed for use with 2.85mm filament. While our open filament architecture does allow for experimental use of other materials, we would advise to avoid promoting the use of 1.75mm size filament if possible. While there have been anecdotal reports of some success, running 1.75mm filament poses a greater risk of clogging, especially on the print cores of the UM3. Remember that any issues that occur due to using a third party material is not covered under warranty, so the use of 1.75mm filament will be at the end user’s own risk.
