Tools for people who sell prints
Four calculators, free and with no sign-up: what a print costs to make, in filament or resin, what an Etsy sale actually leaves you, and how much filament you have in metres or grams.
3D print cost calculator
What one 3D print really costs, including the waste and the failure rate. Free, no account needed.
- Give it
- Filament grams and spool price, print time, printer wattage, and your failure rate.
- Get back
- The true cost of one print, with every layer shown — filament, waste, electricity, machine time and the failure uplift.
Resin print cost calculator
What one resin print really costs, from the mL your slicer reports, with screen wear and failures. Free, no account needed.
- Give it
- The mL your slicer reports, the bottle's price and weight, the resin's density, and your failure rate.
- Get back
- The true cost of one resin print, with every layer shown, including screen wear and the failure uplift.
Etsy profit calculator
What one Etsy sale really pays you after the fees, including the postage inside the fee base. Free, no account needed.
- Give it
- Your sale price, what you charge for postage, and what the postage costs you.
- Get back
- What Etsy keeps, fee by fee, and what actually reaches you per sale.
Filament length and weight calculator
How many metres or grams of filament you have, and what is left on a spool. Free, no account needed.
- Give it
- The material or its density, the diameter, and a length, a weight or a scale reading.
- Get back
- Grams per metre, metres in a kilogram, each converted the other way, and what is left on the spool.
No sign-up and no email address needed for any of them.
Guides that go with them
What does a 3D print actually cost to make?
Filament is the smallest part. Also covers the failure-rate sum that leaves most people's prices too low.
How to price a 3D print
Work out the floor first, then add margin, then subtract what the channel takes.
What selling 3D prints actually pays you
Commission, processing and absorbed postage all come off before you see it.
