How resin print cost is calculated
Resin is sold by volume, and 1 ml of model is 1 cm³. On top of the model itself you pay for supports and raft, resin left on the vat and build plate, and cleaning consumables.
resin ml = model ml × (1 + supports%) × (1 + waste%)
resin cost = resin ml × bottle price ÷ bottle ml
true cost = (resin + electricity + consumables) ÷ (1 − failure rate)
Hollowing a model in your slicer can cut resin use by 60–80% for large solid parts — re-run the numbers with the hollowed volume your slicer reports.
Typical values
| Item | Typical |
|---|---|
| Standard resin | $20–35 per litre |
| ABS-like / tough resin | $30–60 per litre |
| Supports | 10–30% of model volume |
| MSLA printer power | 30–80 W |
FAQ
How much does a resin print cost?
A 25 ml miniature-sized print with supports uses about 30 ml of resin — around $0.90 at $30/L — plus a few cents of power and consumables.
How do I know my model's resin volume?
Your slicer (Chitubox, Lychee) reports it, or drop the STL here to read the solid volume. Remember slicers include supports; this tool adds them as a percentage.
Is ml the same as cm³?
Yes. 1 ml = 1 cm³ = 1000 mm³.
How many prints can I get from a 1 L bottle?
Divide 1000 ml by resin per print. The calculator shows this as prints per bottle.
Recommended gear
- Standard photopolymer resin, 1 L — Good default for miniatures and detail parts.
- Wash & cure station — Washes and UV-cures resin prints in one unit.
- Isopropyl alcohol 99% — For washing resin prints; a wash & cure station makes it easier.
- Nitrile gloves — Always wear them handling uncured resin.
