Why are my spheres printing as hollowed when they're not?

Member Posts: 5 ✭

I'm making a molecule, and I need my spheres for each atom to be solid. The problem is: I've made the solid. The program showed them as solid. However, when I go to print it, they're only shells. What am I doing wrong? How do I fix this? *I need this done by the 9th!*

    It's likely that either they're spherical surfaces (or very thin hollow solids) in Onshape or your slicer isn't generating infill. In the parts list, do you see them under "Parts" or "Surfaces"? And, in your slicer, do you see infill being generated for intermediate layers?

    Are you 3D printing? Maybe depends on how you are slicing before printing?

    It's listed in parts, and I am 3D printing it, but my teacher is the one doing it. I'm not sure how it's slicing it.

    Check the cross-section of the part: https://cad.onshape.com/help/Content/moving.htm?cshid=section_view#View

    If the cross-section is solid (left), then it's a solid part and something's likely wrong in the print step. On the right is a thin spherical shell, which would print hollow.

    If your prints are small, it could be that the infill is too sparse.

    They're solid, so it's probably the printer. I'll make sure nothing's going wrong there. Thank you!
