Your Resin 3D Print Calculator — Exposure, Time &
Calculate resin print time (exposure + lift), resin volume and cost, the exposure time from your resin's cure depth (working curve) and your screen's pixel.

What is the Resin 3D Print Calculator — Exposure, Time &?
Resin printing has its own arithmetic. Print time is not just layers × exposure: every layer also pays for a lift, retract and wait cycle, which is why thin layers print slowly. Enter the model's volume and height (or drop in an STL to fill them), layer height, bottom layer count and exposures, lift height and speeds and the wait times, and the calculator returns total print time, per-layer time, resin needed including supports and failure allowance, and the cost per print including resin, IPA and electricity.
Two more calculators sit below. The working-curve calculator uses Jacobs' relation Cd = Dp·ln(E/Ec): enter your resin's penetration depth and critical energy and your screen's light intensity and it gives the exposure time needed to cure a chosen depth — a starting point for exposure tests. The pixel-size calculator turns your screen's resolution and width into the XY pixel pitch, showing the real detail limit of your printer.

Questions people ask
Is the exposure model accurate?
It is the standard Jacobs working-curve model — a good starting point, to be refined with test prints.
What is Dp and Ec?
Dp is the resin's penetration depth, Ec its critical energy; both come from the resin supplier or exposure tests.
Can I load an STL?
Yes — volume and height are filled in; add support height manually.
Is it private?
Yes.
How do I use the Resin 3D Print Calculator — Exposure, Time &?
1. Optionally drop your STL for volume and height. 2. Enter layer height, exposures, lift and wait times. 3. Set supports, waste and resin price. 4. Read the time, resin and cost; use the exposure calculator for tuning.
