Polish the plaster surface, not the 3D-printed shell-mold
Monday 2nd December 2019
This plaster model was just removed from the 3D-printed shell behind. It dropped out easily (after tapping it at-an-angle on the corners), this worked well despite the resolution lines on the surface. While I could have spent time sanding and smoothing the inside of the shell-mold, it is actually far easier to smooth the surface of the plaster form after extraction. Seconds with a metal rib completely smooths any of the surfaces. And remember, it is easier to remove plaster items cast inside of 3D-printed molds rather than cast around the outside of them.
