Problems with infill

Last updated 6 months ago
This article is also available in following languages: 

Various problems with infill are not the worst kind of trouble you may come across, however, in some cases it can put the structural integrity of your prints at risk. The ideal time when you should check whether the infill is okay or not is when the object is still being printed.

Choose infill-type based on the application of the part. For mechanical parts, we recommend 3d-infills like Cubic or Gyroid. Otherwise, Grid will serve most purposes, but may not be perfect for all geometries.


  1. Change infill type – Certain infill types are more difficult to print, such as the cubic infill. Try using a different one, if possible.
  2. Flexible filaments – Do not try to print complex infill patterns with flexible filaments. This type of filament is especially vulnerable to imperfect infills. The best bet is to use the GRID infill when printing flexible filaments. You can change the infill pattern in the PrusaSlicer – Print settings – Infill – Fill pattern.
  3. Lower the printing speed – If none of the above helps, try to slow down the printing speed of the infill. This can be done in PrusaSlicer in the Print settings – Speed – Infill.
