3D printing calculators
The same engine that runs inside the Gyroid app, free on the web. Every calculation happens in your browser: nothing you type is uploaded, stored, or logged.
3D print cost calculator
Filament, electricity, and machine depreciation for a single print. The number you need before you quote a part or decide whether to reprint.
Weight and lengthFilament calculator
Grams to metres and back, by material and diameter, plus how much is left on a part-used spool once you subtract the empty spool weight.
Power per printElectricity cost calculator
What a print actually draws from the wall: printer wattage, hours, and your kWh rate, including the heated bed and enclosure.
Which one do you need?
- "What did this print cost me?" — the cost calculator. It adds filament, power, and machine wear into one figure per print.
- "Will this print finish on what's left?" — the filament calculator, then weigh the spool and subtract the empty spool weight.
- "Is my printer expensive to run?" — the electricity calculator. Usually less than people expect, and worth knowing before you argue about it.
The reasoning behind all three is written up in the guides: what a 3D print actually costs and how much filament you need.
Or stop typing the numbers in
Gyroid does all three automatically for every print you log, deducts the filament from the right spool, and keeps the running totals per printer. Private, offline, no account.
