A resin domino mold for a complete double-six set, all 28 tiles from blank-blank to six-six in one block. Each tile is 40 x 20 mm and 8 mm thick, with rounded corners, chamfered face edges, a groove across the middle and every pip pressed in as a 3 mm dimple, ready to fill with paint. The whole set takes about 176 ml of resin.

Made with the box mode of our silicone mold maker, the mode the tool itself suggests for this shape. The tiles stand face up on the printed base, so the silicone block you pull off is an open-face mold: each face forms on the floor of its cavity, glossy against the silicone, and the back is the open top that levels itself. A 0.3 mm hairline joins the tiles on the base so the master is one piece; at most it leaves a film on the back that peels off. Print the base, the two walls and the two clamps, and pour about 1000 ml of silicone.

Pour clear resin with dried flowers, coloured resin with mica swirls, or glow powder for a set that plays in the dark, then paint the pips in a contrasting colour. The zip carries every printed part, the domino master as its own STL, the tool's own print-settings sheet and a recipe file for the generator.

What you need

4
  • About 1070 ml of platinum silicone, Shore 20A to 30A (mix it in one batch)
  • Epoxy casting resin, about 176 ml per set, plus pigment, mica or inclusions
  • A level surface, a heat gun or torch for the bubbles
  • Acrylic paint or paint pens for the pips, wet sandpaper from 400 grit for the backs

How to cast it

7

  1. Print the base with the master fused onto it, the two walls and the two clamps.

  2. Stand the base on the table. Set each wall 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 slide the clamps down over the seams. Once they are on, the walls cannot lift, and the ridge seals the bottom.

  3. Mix 1070 ml of silicone in one batch and pour it into a corner, letting it rise around the master until it covers the top.

  4. Once it has cured, take the clamps off, slide the walls straight out and pull the silicone block off the master. That block is your mold.

  5. Set the mold on a level surface, open face up. Mix the resin slowly, pour each cavity to just below the rim, and pass a heat gun over the top to pop the bubbles. Pour coloured layers or add inclusions in two pours if you like, with a short wait between them.

  6. Let it cure as long as the resin says, usually 24 to 72 hours for a pour this thick, then flex the silicone and pop each tile out face down. Sand any edge on the backs smooth.

  7. Fill the pips and the middle groove with acrylic paint, wipe the face with a damp paper towel held flat so the paint stays only in the dimples, and let it dry.

Questions about this design

Which resin is best for dominoes?

A deep-pour or casting epoxy rated for 1 cm layers, because each tile is 8 mm thick: a thin coating resin gets hot in a pour that deep and can yellow or crack. Tiles in a casting resin are hard enough to play with after about three days.

How do I paint the pips on resin dominoes?

Dab acrylic paint or a paint pen into the dimples, wait a few minutes, then wipe across the face with a slightly damp paper towel or a card held flat. The paint stays in the pips and the groove and lifts off the glossy face. Seal with a thin coat of resin or varnish if the set will see a lot of play.

How many domino tiles are in a double-six set?

Twenty-eight: every pair of numbers from zero to six once, from blank-blank to six-six. This mold has all 28, so one pour makes a full set.
