Cura does not fix the mesh topology on the 3D model. It actually does most of the fixing in the 2D slices.
So what the CuraEngine does, it slices the 3D model in 2D slices, which results in a lot of 2D lines on the 3D plane. With these lines it tries to make fully enclosed 2D polygons. The rest of the engine works on these 2D polygons.
Just to clarify, Daid: When checking the 4 "fix horrible" settings - does this only affect the algorithm *after* slicing to a 2d polygon? Does this algorithm ignore layers above and below the current layer?
We don't often release an alpha version of Ultimaker Cura... So what's different this time? This Alpha contains such a huge slicing engine overhaul that we really need your help!
We wish to celebrate and honor the innovators that push forward the field, technology and world. We opted to not present it as a competition or ranked list. Every innovator has earned his spot on that list in their own way. We also look at the 3D printing industry as a whole and not limit the list to those only using Ultimaker.
