Work out resin volume for mould instantly with clear inputs, formula shown and shareable results.
Cavity volume in cubic centimetres equals millilitres, and the two parts are split by the mixing ratio so that A plus B equals the total. Epoxy ratios are chemically exact, so mixing by eye leaves an under-cured tacky surface that cannot be fixed after the fact.
Cavity volume
ml = length x width x depth in centimetres
Part split
hardener = total / (ratio + 1); resin = total - hardener
ml = length x width x depth in centimetres. Cavity volume in cubic centimetres equals millilitres, and the two parts are split by the mixing ratio so that A plus B equals the total.
Epoxy ratios are chemically exact, so mixing by eye leaves an under-cured tacky surface that cannot be fixed after the fact.
Enter mould cavity length, mould cavity width, pour depth, parts of resin per part of hardener. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
