Where do I find the model volume?

Your slicer software (Chitubox, Lychee Slicer, PrusaSlicer, etc.) reports the model volume, usually in cm3 or mL, after you load and orient the model. Look for a "volume" or "model info" panel.

Is 1 cm3 really the same as 1 mL?

Yes. A cubic centimeter and a milliliter are the same volume by definition, so the model volume from your slicer converts directly to milliliters of resin with no extra conversion factor.

Why add a supports and waste percentage?

The slicer-reported model volume only covers the solid part itself. Supports, rafts, the resin film left on the build plate, and general spillage during pouring all add extra consumption. 15-30% is a common starting range, but dense support structures can push it higher.

How do I estimate cost per bottle instead of per liter?

Switch the cost mode to "per bottle" and enter the bottle price along with its volume in milliliters (check the label, commonly 500 mL or 1000 mL). The calculator works out a price per mL from those two numbers.

Does this account for resin lost in the vat between prints?

No, this calculator only estimates the volume consumed by the model, its supports, and your waste percentage. Resin that stays in the vat for the next print is not counted as consumed.

Summary

Enter your model volume and a supports/waste percentage to get the resin volume needed in milliliters, plus an optional cost estimate.

How it works

Enter the model volume in cubic centimeters (cm3), shown by your slicer (Chitubox, Lychee, PrusaSlicer, etc).
Enter a supports and waste percentage to cover support structures, rafts, and spillage.
Set the number of prints if you are batching several copies in one run.
Optionally enter a resin price per liter or per bottle to estimate cost.
The calculator converts model volume to milliliters (1 cm3 = 1 mL) and adds the waste percentage.
Results show resin needed per print, total resin for the batch, and estimated cost.

Use cases

Checking whether a resin bottle has enough left before starting a print.
Estimating resin cost for a miniature or model before committing to print it.
Planning how much resin to order for a batch of several identical prints.
Comparing resin usage between two versions of a model with different support structures.
Working out cost per print for a batch of commissioned miniatures.
Converting a slicer-reported volume into a real bottle-refill amount.
