Cura 2.3.1: Slicing error with vase-like objects from massive models

Recommended Posts

If you print a massive model with no infill and no top layer, you should get a vase-like object with only inner and outer layers. However, in some cases Cura finds it necessary to print some extra blobs here and there, ruining your print, like in the example in the pictures. The wall was too complicated probably. If you have simple walls, this works just fine.

Use spiralize outer contour. This will make it so there are no travel moves and it will just go around the outer edge.

You have really bad stringing from travel moves that either are not retracting, travel speed to slow, or you are printing really hot.


There shouldn't be any travel movement, that is the point! Spiralize is useless in this case, because the thickness of my wall is 3 times the nozzle size.

But I'm not really looking for a solution, I'm reporting an error in Cura 2.3.1.

It appears that if the vertical thickness of any given set of layers is less than the top or bottom layer thickness, Cura fills it in with yellow 'infill', and jumps around to set all these areas.

You can minimize this somewhat by setting the bottom layers number to a smaller number (like 1) - leaving the top at 0.

    • "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.
