How can we create 3D printed slip casting molds larger than the print bed? We need to split them apart! Here I build on ways to attach 3d printed parts together to be able to pour plaster slip casting molds. The outer shell is printed in several parts and assembled together using threaded inserts and foam gasket to create a strong plaster tight seal. That is attached to an inner mold (although I had a few bugs in my software that need to be fixed!) Pour in plaster and then disassemble. Once the screws are removed the outer mold basically falls off and the inner mold can easily be removed by making very cold. Best of all, all of the 3D models needed for this are automatically generated from a simple 2d sketch using my software.
