The mold is exactly what our two-part candle mold generator builds for this shape, set to resin: two rigid halves with rubber-band grooves, pry pockets, a pour funnel on the head and a thin air vent. A turned shape always pulls straight out of a split that runs through its axis, which is why the tool's own seam check finds nothing stuck on this pawn and why you need no silicone.

A chess set needs sixteen pawns, eight of each colour, and that is what a rigid mold is good at: print it once, then cast pawn after pawn from the same halves. Cast them in black and ivory resin, or in plaster and paint them. The zip carries both halves, the pawn master as its own STL, the tool's own print-settings sheet and a recipe file that puts every setting back on the generator.

How this mold works

What you need

4
  • About 13 g of casting resin per pawn: the cavity holds 12 ml
  • Mold release spray or wax
  • Rubber bands or clamps
  • A craft knife and fine sandpaper for the sprue

How to cast it

5

  1. Print both halves as exported. Clamp-strength settings: 4 walls, 40% gyroid infill, no supports. Sand the seam faces flat if your first layer came out rough.

  2. Coat both cavities with mold release and let it flash off. Close the halves and band them along the whole seam.

  3. Mix the resin and pour it slowly down one side of the funnel so the air can leave through the other side and the vent.

  4. Leave it to cure fully, as long as the resin's datasheet says, then open the halves at the pry pockets.

  5. Cut the sprue off the top of the head, sand it round and trim the thin line along the seam. Release again and cast the next pawn.

Questions about this design

Which resin works best for chess pawns?

A slow-curing casting resin or a polyurethane casting resin. Slow epoxy gives a glassy finish and fewer bubbles in a small solid piece like this; fast polyurethane cures in minutes, so you can cast a whole row of pawns in an afternoon. Tint half the batch black and half ivory.

Does the seam leave a line on the pawn?

A fine line runs up both sides where the halves meet. Clamp evenly along the whole seam and it stays hair-thin; a sharp blade or 600 grit paper takes it off in seconds, and it is on the side of the pawn, not across the head.

Can I make the rest of the chess set with this tool?

Yes, any turned piece works the same way: rook, bishop, queen and king all release from a split through their axis. Upload your own piece to the free two-part candle mold generator. The knight is the exception, since its head hooks into both halves, so it is a silicone job.
