We pour mold walls 10mm thick (because molding rubber, like PMC-746, is expensive and heavy). Normally a large mold like this would stretch completely out of shape when plaster is poured. But with these 3D printed rails there is no problem. This mold needs two of them. On the smaller 3D printer (top left) they need to be done in four pieces and glued together (lower left). But on the larger 3D printer they can be done in one piece (upper right). While many 3D printing tasks are better done by chopping objects up into smaller pieces and gluing them, this type of thing is an exception.

Side Rails
Side rails are the containment used when pouring plaster molds. We 3D-print these to custom fit each mold. |
