Resin Volume Calculator — Resin Quantity for Moulds
Calculate resin volume, Part A and B weights, catalyst drops, pot life and cure time for any mould shape.
How We Calculate This
This calculator estimates resin volume using geometric formulas for each mould shape, then calculates Part A and B quantities based on your mixing ratio.
The formulas
Rectangle: L x W x D
Cylinder: \u03C0 x (D/2)\u00B2 x Depth
Dome: (2/3) x \u03C0 x (D/2)\u00B3
Net volume = Mould volume - Embedded objects
Total = Net volume x (1 + Wastage %)
