Underextrusion

Updated 10 days ago ​by Tomáš Chvalina

If there is not enough material in your print, you can see gaps in places, where full shell should be instead. In 3D printing we call this phenomena underextrusion and not enough material is flowing through the nozzle.

Check following:

  1. Make sure that you are using proper settings for proper material. As well as if there is only slight underextrusion. It shall be tweaked with minor temperature change. Recommended temperatures are usually to be found on the spool.
  2. Check that you do not have your Extruder driver gear (Pulley) full of filament dust. Also seek for the upper part of the extruder, where you need to have sufficient pressure by tightening screws.
  3. Many failed prints can be result of clogged nozzle, because not enough material is flowing through. You can check more information about clearing nozzle in Clogged nozzle.
