Prepare for 3D printing

  • watertight
  • not too many intersections
  • avoid small details (0.8mm minimum detail, but tall objects should be thinker)
  • if part snaps together with other part: allow clearance
  • if part snaps together with other part: make sure the part can be inserted

Cura is slow

  • If Cura is slow: set the option “Infill > Skin Edge Support layers” to 0

Per model settings


Use different slicer settings in the volume of a selected object.

Example: use a more dense infill in a specified area

  • Add the object you want to print.
  • Add the object you want to define the dense infill with (a cube could work just fine).
  • Change the size and position of the second object so it overlaps the first object at the desired location.
  • Select the second object. In the side bar, go to per model settings and select Modify settings for overlaps.
  • select infill mesh only
  • select the following settings:
    • Wall line count: 0
    • Top Layers: 0
    • Bottom Layers: 0
    • Infill Density: the desired value for your print


When you're using Gradual Infill Steps in your main model, don't forget to add Gradual Infill Steps: 0 to the per model settings

Calibrating for correct dimensions

  • Isolate a small piece of your model which you can use for a fit-test.
  • In Cura, set the Horizontal offset to a negative number (in mm) to make the model leaner in the horizontal plane. Set it to a positive number to make it fatter. Use small values like for example 0.1mm.
  • Print the test piece and measure it with calipers.
    • If the dimensions are different than the CAD model, adjust the horizontal offset.
    • If the dimensions are the same as the CAD model, but it doesn't fit properly, adjust the clearance values in the CAD model.
