The "spares" (in the slip casting mold on the left) act as built-in reservoirs to hold the extra slip needed (because of volume reduction during the casting process). These are the traditional way of making molds. However CAD and 3D printing enables rethinking this. The two 3D-printed pour spouts (top) glue onto the assembled mold on the right.
These 3D printed mold spouts have been designed to perfectly fit onto this handle mold (they glue on with slip). On pour-out they can be removed and enable precisely cutting the join surface. The spouts are cleaned by allowing them to dry and throwing them into a bucket of water (the clay slakes off).

Pour Spout
Plaster molds intended for slip casting have a spare at the top to act as a reservoir. This enables overfilling the mold to accommodate the dropping slurry level. 3D-printed spouts make a spare unnecessary. |
