After our success, with glass casting in VOHP plaster (USG Hydroperm), we had a discussion in the lab about “What’s next?”. The students in the lab are working on their final two class projects, one of which involves printing molding masters. They use the masters to create plaster molds for slip casting. It seemed like a natural thing to try 3D printing of slip casting molds.
We printed a simple two part mold for our test pot – SW Pot. The resulting molds looked just fine but how would they perform? We tested the mold pair with low fire slip (also known as talc-body slip). It seems that the printed molds performed at least as well as traditionally created plaster molds.
It seems that our students will be producing slip casting molds a new way in the future.
