For: Ceramicists and makers preparing molds from 3D models
Worth noticing: It plans mold pieces around locking and trapped-air points, then lays printer-bed-sized cases out on plates with alignment pins.

Field notes

The listed workflow accepts five 3D file formats and can also start from an example model. The site describes checking and repairing uploads, planning mold splits around locking and trapped-air points, and arranging printable cases with alignment pins. A pour sheet supplies quantities and sequence for plaster or silicone; downloading the print files requires an account.
