Resin Print Calculator
Forty parts take the same time as one.
Work out Resin Print. Forty parts take the same time as one. Counts the thing everyone forgets to count.

Resin print time depends only on height. Every layer exposes the whole build plate at once, so one part and forty parts of the same height finish together — the exact opposite of filament printing, and the reason to fill the plate. Supports and raft are usually a quarter to a half of the model's own volume, and they are pure waste. Orienting a part to reduce supported area saves more resin than any setting. Resin shrinks on cure, typically 1 to 2.5%, and it shrinks after printing as well as during. Parts that need to fit something should be modelled oversize by the shrinkage figure, or measured after a full post-cure rather than straight off the plate.
How the Resin Print Calculator works
Resin volume, cost, print time and cure shrinkage for an MSLA printer. Print time depends only on height, because every layer exposes the whole build plate at once.

Frequently asked questions
Does printing more parts take longer on a resin printer?
No. Every layer exposes the whole plate simultaneously, so forty parts of the same height finish with one. Filling the plate is effectively free — the opposite of filament printing.
How much resin do supports use?
Typically a quarter to a half of the model's own volume, and it is pure waste. Orienting a part to reduce supported area saves more resin than any slicer setting.
How much does resin shrink?
Between about 0.7% and 2.5% depending on formulation, and it continues during post-cure. Parts that must fit something should be modelled oversize or measured after a full cure.
Is resin dangerous?
Uncured resin is a skin sensitiser and an irritant, and sensitisation is cumulative — people who skip gloves often develop reactions after months of no trouble. Nitrile gloves, eye protection and real ventilation are not optional.
How do I dispose of resin waste?
Cure it first. Cured resin is inert and goes in general waste; uncured resin and washings must never go down a drain. Leaving waste in sunlight until fully hardened is the simplest method.
