ResinBatch

ResinBatch helps resin crafters and woodworkers plan quantities before mixing. Combine different mold shapes and counts into a batch estimate, calculate tabletop coating and river-table cavity volumes, or split a known batch using the weight or volume ratio specified for your resin. The four free browser calculators support metric and US units, extra-resin allowances, printable plans and CSV exports. Free worksheets help record measurements and pours. No account is required. Saved mold projects stay on your device, and share links carry batch measurements. These are geometric quantity estimates. Follow the instructions for your exact resin, including the correct ratio basis, maximum batch size and permitted pour depth.
