Cura fills hollow objects

Recommended Posts

Im using CURA 14.03.

The word you see was made hollow, only the walls (outer shells) of the letters are present, and 0,5mm thick. The bottom board should be, and is 100% filled, but the letters arent supposed to be filled at all.

Is there any way to set that only the board at the bottom is 100% filled, but the letters remain hollow? Cause if I set it to 0% fill the board is empty then.

At 100% fill cura fills everything:


It should be like this:


Or maybe I am just overseeing something? Or its not possible?

There's 2 possibilities:

1) Your model is bad.

2) You have some of the "fix horrible" checkboxes checked.

So first check that you don't have any of the "fix horrible" checkboxes checked. I think "type A" is checked by default. It's in the expert settings.

If this doesn't help you can play with the other checkboxes in fix horrible. To see the mistakes in your model do "xray view" instead of layer view or normal view. Anything in red is an area that has an extra wall or a missing wall (a hole).

Consider using cad software (like design spark mechanical, orscad, solidworks or hundreds of others) that *only* allows you to create manifold 3d parts (unlike sketchup where it starts out with a 2D person which is nothing like reality or real parts).

Nothing horrible is checked.

I will re-check my model. The word was made in Inkscape and imported to Blender as SVG, and the board itself was made directly in blender. So maybe somewhere along the way I messed something up or simply didnt do.

Your model has no volume. That's why this is happening.

Cura looks from the side of the model, and then looks trough the model, for every polygon it passes, it "fills" until it passes another polygon.

"Manifold mesh" is another keyword you would want to look at.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
