How to make a solid shell from a surface mesh (.stl or obj. file) - Fusion 360 & MeshMixer

Let's learn how to make a solid shell from a 3D scanned mesh like an .stl or an .obj file using Fusion 360 and MeshMixer!

Thanks HEAPS for this Adam!! You have no idea how long it took me to find a solution to what I thought was a super simple problem. I usually use Blender for modelling but with the complex mesh I'm working with I was unable to shell it. Meshmixer did the trick perfectly! Fusion 360 however, has to be one of the worst pieces of software I've ever used 😂 Side note for those wanting to print their shell, you can skip the "Make solid" step [especially as Fusion kept crashing and refused to do mine] because your slicing program will automatically fill the cavity between the two walls before printing 👌 Cheers, Rich

Thank god! I found your vid 😂.That’s what I’ve been struggling for like 3 days trying to fill hollowed dental models that was taken by 3d scanner.

Thank you! I’m going to try that

Of course!

Hi. Thanks again for all your help! I'm trying to take a cylindrical mesh from 'image to lithophane' and convert it to a solid hollowed body so I can print it out and put a tea light in it for a present for my Dad. I went through these steps; however, the challenge I have is that at the reduce mesh option, even if I drag the proportion to 1, I still have over 10,000 triangles remaining and it doesn't work. The detail is also almost all but gone even at this amount of triangles with the proportion at this level. Any ideas of what I'm doing incorrectly? Thanks for sharing your expertise!!!!

@@adamtjames LOL! Sorry about that! This is after I looked at that one too. I meant to put this question in there. Would you like me to put this question in that one? Thanks again!

Awesome!! Thanks

GREAT

Would it be possible to shrink the shell in Meshmixer by scaling down so the final resulting model had thicker walls? I'm trying to find a way to thicken a stl file of a car body to make the printed shell thicker at smaller scales. Thanks for the information you provided.
