Resin Calculator for Dice, Chess and Domino Sets

Pick a set, adjust the number of pieces and the volume of each cavity to match your mold, and get how much resin to mix in total and per batch.

Mixing

Dice molds need more extra than flat molds because of the sprues and small cups.

How to use this calculator

  1. Choose dice, chess or dominoes.
  2. Change the counts and the ml per piece to match your mold. The water test gives the exact number.
  3. Enter how many colors you will mix. Each color is a separate small batch.

How the calculation works

  • Mold volume = sum of (count × ml each) × number of sets
  • Mix total = mold volume × (1 + extra %)
  • Resin = total × A ÷ (A + B); hardener = total × B ÷ (A + B)

Tips for dice and game pieces

  • Use a casting resin with a long working time so bubbles can rise out of small cavities.
  • A pressure pot gives the clearest dice, but slow pouring and warm resin also help.
  • Pour a little over the top of each cavity; you sand the sprue flat after demolding.

Frequently asked questions

How much resin do I need for a dice set?

A standard 7-piece polyhedral set holds about 24 ml of resin. Mix about 30 ml (25% extra) to fill the sprues and allow for what stays in the cup.

How much resin for a chess set?

A typical 32-piece resin chess set needs roughly 398 ml for the pieces, or about 17 fl oz with 25% extra. Large tournament-size molds can need much more.

How much resin for a domino set?

A 28-tile double-six set with 2 × 1 inch tiles takes about 344 ml, or 15 fl oz with extra.

How do I find the exact volume of my mold?

Fill each cavity with water, pour it into a cup on a gram scale and read the weight. One gram of water is one milliliter. Enter that number for the piece.
