What problem is this?



  • Hi,

    I tried to print a lithophane globe, but it failed half way trough.
    Does someone know what this problem is called? Then I'm sure someone already has a solution.

    I have a Ender 3 V2. I used the following print settings in Cura 4.2.1:
    Standard Quality 0.2mm
    infill 100%
    no support
    Build Plate Adhesion Type: None

    Thank you!

  • @Kaelum Thank you for your reply!
    Those strings already start when he is still printing pretty vertically. So maybe it is not just because it's a sphere?



  • Probably somebody else knows, but in the meantime, maybe you try some of the checks/adjustments mentioned here

    Should be able to narrow it down before spending the time on another of those globes.



  • The print angle near the top of the sphere is too high. All spherical objects have this issue. You need to use supports, which can be tricky. You are going to need to support the top ~1/3 of the sphere in some way.
