Silicone mold

Cast resin, plaster, wax or soap. A printed box you fill with silicone. The set silicone is the mold: it stretches off shapes plaster would lock.

Bring: Figures, tiles and anything with undercuts.

How it works

1. Bring a model: upload your own STL, OBJ, GLB, PLY or 3MF, or start from an example. It is checked and, if it needs it, repaired.
2. Pick the pieces: the mold is planned on the model, with where it would lock and where air would be caught, then generated.
3. Get the print files: the cases are cut to fit your printer bed, with pins so they line up, and laid out on plates.
4. Print the cases and pour: the pour sheet says how much plaster or silicone to mix, and in what order to work.

Open the silicone mold tool, or start from an example.

The other tools

• Slip-cast mold: Slip-cast a vessel or a figure. A plaster mold in pieces. Pour in liquid clay, wait for the wall to build, pour the rest back out.
• Press mold: Press tiles, sprigs and dishes. A plaster mold you press soft clay into: one open piece, or pieces that close on each other.
• Hump mold: Drape a dish over a hump. A plaster hump on a plinth. Roll a slab, drape it over, trim it along the line.
