Thin wall sliced as inner wall

Recommended Posts



I would like to ask for your help. I was going to print calibration thin wall "cube", but I already see that Cura sliced it as yellow inner walls, resulting in some walls not being straight lines, but bunch of short angled pieces instead. I attach a screenshot. If you can help me with some advise how can I set it to straight outer wall lines, I would be really grateful. Thank you!

Thank you for reply. I enclose today's file, because I didn't save the previous one. Hovewer, there is the same issue. This is Cura 3.6 now, but previously it was 3.5.1 (just updated today).


EDIT: Also, "print thin walls" is enabled, of course. Without it, it didn't want to slice it at all.

Hello @Wizzeros. I'm afraid that with the current Cura, that is what you get when you ask it to print thin walls. Arguably, it does not do a good job. By coincidence, I have recently been working on a related part of Cura that fills gaps between walls and I think the technique I have used there could also be used when printing thin walls. Perhaps in the future, Cura will handle this better.

    • "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.
