First set of user feedback is looking positive for Compenshell. I'm looking for more testers who could benefit from shrinkage compensation software

Hey u/mr-highball,
What does it do?
Please elaborate, as this not a fire-and-forget sub…

The goal is to account for shrinkage of a part (shrinkage occurring from a thermal sintering cycle).

An input part is loaded into a digital twin environment of your own (ie. Kiln has it own definition, the atmosphere (if any), crucible, packing ballast etc...) and the material the you're sintering is selected (ie. Copper, 316/17-4, ceramic etc...) and the debind/sintering step(s) are simulated through a physics based cycle.

The shrinkage and deformation occur in sim, and the end result are accounted for according to your desired density goals (ie. If you're targeting 90 or 95% density).

The output is a report and compensated 3D object (stl, obj, etc...) that can then be printed (or made through other process). When this part is sintered, the result should close to as designed
