Fill hollow part of body in the 3D model Sorry, I'm new in 3D printing and modeling and I need help.
I bought a 3D model with a hollow part of the body that doesn't print on my printer normally (with very high resolution (layer is 0.12 mm, the nozzle is 0.4 mm) because the walls are very thin).  I tried to make it as a solid in MeshMixer or ZBrush, but  I can't.  Can you help me, how I can fix this defect?
I use Cura for slicing.
I know, that I can take a thinner nozzle (0.2 mm) and Cura will slice it better, but I want to make this model solid so I could print it with nozzle 0.4 mm.
This is a problem with the model, you need to make sure that the model isn't hollow. You might be able to get around this though if you use scaffolding, it might recognize the overhand hand build supports for your print inside of your print, you just might have to mess around with the scaffolding settings a bit.
