Pouring was made possible using a 3D-printed PLA pour spout. This enables overfilling the mold. The overhang lip is still optional, it was not possible to dry them enough to remove them from the mold without cracks appearing under the overhand (although if the mold is laid down as soon as possible after pouring this could work). Later we modified the spout to be flush with the inner wall and taller. And we added a drain hole so that pour out was not necessary - the spout thus just acts as a reservoir. Shortly after pour out we were able to remove it and cut the wall flush with the top edge. This enabled the clay to pull away from the mold with equal resistance all the way around, resulting in amazingly straight-walled pieces. And very thin walls were also possible.

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 left. 3D-printed spouts make a spare unnecessary. |
