Resin Print Cost Calculator
Resin printing has hidden costs beyond the bottle — supports, failed prints, wash alcohol, and FEP wear all add up. Enter your print and get an honest cost per piece, plus a selling price if you sell your work.
Per litre
Slicer reports the model volume. Supports and a failure allowance are typical defaults — adjust to your setup and print reliability.
Consumables & markup
Per litre
Gloves, towels, etc.
Leave at 0 for cost only. FEP wear is the film's cost divided by how many prints it lasts.
Formula & how it works
Resin used = model volume × (1 + support %) × (1 + waste %), and resin cost = resin used ÷ 1000 × price per litre.
Consumables = wash alcohol cost + FEP wear + other per-print items. Total cost is resin + consumables, and selling price applies your markup on top.
Worked example
A 30 mL model with 30% supports and a 10% failure allowance uses about 42.9 mL of resin. At 30 per litre that is roughly 1.29 in resin. Add 40 mL of alcohol at 5 per litre (0.20), plus 0.30 of FEP wear and 0.15 of odds and ends, and the print costs about 1.94. With a 300% markup it would sell for about 7.75.
Where resin costs hide
Supports and failures are real resin
The model volume from your slicer is only part of the story. Supports can add a third or more, and even a good printer wastes resin to occasional failures, cleanup, and the film of resin left in the vat. Folding those in with a support and waste percentage keeps your per-print number honest rather than optimistic.
Consumables add up over a spool's worth of prints
Isopropyl alcohol, FEP or nFEP film, gloves, and paper towels each cost little per print but recur every time. The FEP figure is the film's price divided by how many prints it survives before clouding or tearing. Tracking these stops a batch of "cheap" prints from quietly eating your margin.
Price for your market, not just cost
Cost per print is the floor; a selling price needs to cover your time, equipment wear, and the risk of reprints. The markup field lets you test a price quickly, but treat resin printing's cost as one input into pricing rather than the whole answer.
