We are just using pottery plaster for now. Notice the embeds for the natches. This time I did not backfill the 3D prints, that is better - because they are flexible they were much easier to remove from the set plaster. The side rails help keep them firmly in place and scotch tape on the backs was sufficient to keep them lined up at the join. These prints have a wall thickness of only 0.8mm. I did not need to use a parting agent nor did I do any smoothing on the 3D prints (although some cleanup on the plaster case mold will be done). Next step: A working mold, version 4.
