Slicers

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

• 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.
