The Barberini Faun as a 110 mm statue: a satyr asleep on a rock draped with an animal skin, one arm thrown over his head, utterly relaxed. The Hellenistic marble from around 220 BC is in the Glyptothek in Munich and is one of the most daring sculptures of antiquity.
The master is a 3D scan of the plaster cast of the Barberini Faun in the Royal Cast Collection of SMK, the National Gallery of Denmark, published by SMK as public domain. The mold is made with the hugging-shell mode of our silicone mold maker, the mode the site's own mold advisor picks for a statue: every fold and limb would lock a rigid two-part mold, and silicone peels out of them.
He is wide and sits low, which makes him a sturdy cast in plaster, Jesmonite or fine concrete, for a shelf, a mantelpiece or a garden corner. The same mold also takes resin, soap or candle wax.
Print the base with the statue fused onto it, the two shell halves and the six clamps that hold them shut (all six are in clamps.stl, no binder clips needed), pour about 197 ml of silicone, and cast in the flexible mold that comes out. The zip carries every printed part, the statue as its own STL, the tool's own print-settings sheet and a recipe file for the generator.
Shown as a 3D render of the printed mold parts, the six printed clamps and the cured blue silicone mold they make, not a photo.
Print the base, which has the statue already fused onto it, the two shell halves and the six clamps (all six are in clamps.stl, laid out on one plate). No supports.
Stand the base on the table. Set each shell down a few centimetres out from it and slide it in over the table until the ridge round the base sits in the groove at its foot, then push the six printed clamps over the wings, three down each seam, so the shell is clamped shut from top to bottom. Steel binder clips work too.
Tape the outside seams or run a bead of hot glue along them, because silicone finds every gap.
Mix 222 ml of silicone in one batch and pour it into the opening on top in a thin stream until it is full.
Once it has cured, take the six clamps off, slide each shell straight out and peel the silicone off the statue. That silicone is your mold.
Before the first cast, read the notes in PRINT-SETTINGS.txt: if they flag air trapped in the cast, cut a thin vent in the cured silicone from that spot toward the opening with a craft knife, so the plaster fills it.
Set the silicone back in the shell to keep its shape, and pour plaster, Jesmonite or fine concrete into it through the opening the base left. Tap it for a minute so the bubbles rise.

About 197 ml, so mix 222 ml in one batch. The shell follows the figure, which is why it takes far less than a box around a statue this size would. A tin or platinum casting silicone of Shore 20 to 30 A works well.
With six printed clamps, all in clamps.stl in the zip. The two shell halves have wings along both seams; push three clamps over each seam, top, middle and bottom, and the shell is closed tight with no gap for silicone to escape. Tape or a bead of hot glue along the outside seams on top of that makes it leak-proof. If you have steel binder clips, a few more never hurt, but you do not need them.
From SMK, the National Gallery of Denmark. Its Royal Cast Collection holds plaster casts of famous sculptures, made in the 19th century so artists could study them, and SMK has 3D scanned many of them and published the scans as public domain. This is their cast of the Barberini Faun in Munich. We only cut it flat under the plinth, scaled it and simplified the mesh for printing.
He reclines, so his rock is about as wide as he is tall. At 110 mm tall he sits next to the 140 mm standing statues at a matching scale, and the mold stays one batch of silicone.
Yes. They are all scans from the same museum collection, made at a matching shelf size (most stand 140 mm tall), so a few of them cast in the same plaster make a small sculpture gallery for a shelf or a mantelpiece.
