Resin print cost calculator
Resin math has one extra step filament doesn't: slicers report volume, but resin is sold by weight, and density is the bridge. This resin cost calculator takes your model's volume, applies a density of about 1.05–1.12 g/ml for standard resins, adds the 10–30% that supports typically consume, and prices the print against your bottle — a 40 ml mini lands near 51 grams and about $1.95 on a $35 bottle, with roughly 19 prints to the kilogram. The failure allowance is there because failed exposures waste resin and time the same way spaghetti prints waste filament. The note carries the part that isn't optional: uncured resin needs nitrile gloves and ventilation, every time.

How it works
- 01
Slicer volume converts to grams through the resin's density — standard resins run about 1.05–1.12 g/ml — then the support allowance adds its share.
- 02
Cost per print is grams times price per gram, inflated by the failure allowance the way failed exposures eat resin and time.
- 03
Prints per bottle divides bottle size by per-print grams and rounds down — the bottom of the bottle always stays dirty.
