Resin Volume Calculator

Estimate how much resin a print will consume from the model volume, support overhead, raft and failure-buffer percentages — plus how much to pour into the vat including the FEP coverage minimum.

Inputs

Model Volumeml

Read from your slicer (Chitubox / Lychee / Voxeldance). 1 cm³ = 1 ml.

Supports Overhead%

Tree supports add 10-25%; heavy supports for overhangs up to 40%.

Raft Volumeml

A typical Chitubox / Lychee raft for one plate is 3-6 ml.

Failure Buffer%

Safety margin for spillage, splash and partial failures.

Vat Minimumml

Resin needed to keep the FEP covered. Anycubic Mono ~80, Mars 4 Ultra ~100, Saturn 4 Ultra 16K ~150.

Resin Densityg/ml

Standard photopolymer 1.05-1.20. ABS-Like ~1.15, water-washable ~1.08.
