How to add thickness like shown in the screenshot?

[Anonymous]

I am using meshmixer. I am working for a dentist. I have a scanned teeth. I want to add thickness to the scanned teeth like shown in the screenshot. How can I do that?

Depends much on your source mesh (ie the scan).

Is it already watertight or an mesh with open boundaries?

Best if you post a screenshot of your source mesh.

You might use EDIT/Hollow plus  EDIT/PlaneCut on a watertight mesh

or SELECT>SelectAll > Offset plus EDIT/PlaneCut on an open mesh

Guess that's an intern oral scan viewed from below the printer's build volume.

Hint: You can hide rendering of the printer via menu: View>ShowPrinterBed.

So it should be something like this:

First thing you should do is to run ANALYSIS/Inspector on a scan. Do NOT do AutoRepair but manually click all marker spheres but the one pointing to the main boundary.

Now crop off not needed surfaces running EDIT/PlaneCut. Cut at the bottom

and at the rear

Now hit Ctrl+A to SelectAll (the object should be orange totally) and do Modify/SmoothBoundary (this is optional but should give a nicer extrusion):

Accept and run Edit/Extrude with the shown settings (Offset needs to be more than you'll need):

Accept and leave SELECT. Run EDIT/Hollow (here at a wall thickness of 2mm):

Use EDIT/PlaneCut to crop off the base wall:

Done.
