2 thin walls instead of one thick one

Recommended Posts

I'm trying to convert from Netfabb over to Cura, but having one small challenge. In my model, which is a small case for electronics, I have a wall that is 1.23mm wide. In Cura/Printrun, it prints this as two thin walls (inner and outer) instead of just one thick wall. The two thin walls are fairly weak and flex all over the place. The same model from Netfabb produces a solid thick wall. I'm using 100% infill and even increased the infill overlap to 35%, but still not working. I also bumped the wall thickness up to 1.6mm. Any suggestions?

Full disclosure: I'm a new UM owner (and new to 3d printers) in general and I'm at the end of my first week. I seem to be getting better results for my projects from Cura instead of Netfabb.

Try setting the wall thickness to 0.4mm, this should put down 1 side line, and then put infill in between. The problem is well known as the "thin wall problem", Cura refuses to put infill in between thin walls. There are lots of test cases for this, and lots of proposed sollutions, but going from an idea to a real implementation proved to be difficult so far.
