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.
Mould dimension
Length measurement
Width measurement
Depth measurement
Volume displaced by objects
Enter the mixing ratio
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 %)
