FDM Print Cost Calculator
Real cost per FDM print – material, supports, electricity, wear and failure buffer.
Power values are measured averages while printing PLA on popular printers (Bambu Lab A1 mini / P1S / X1C, Prusa MK4, Creality Ender 3 / K1 Max). Electricity prices are approximate household averages per country – adjust to your own tariff for exact results.

About the SANIX3D FDM Cost Calculator
The SANIX3D FDM 3D Print Cost Calculator is a free online tool that shows the real cost of every FDM print, not just the filament. Enter the part weight and print time from your slicer, pick your printer and electricity price, and get an instant cost per print – filament, supports, electricity, printer wear and a failure buffer, in EUR, USD or GBP. It is built for makers who sell prints, run a small print farm, or simply want to know what a model really costs before hitting print.
How to use the FDM cost calculator
- Enter the print details – part weight in grams and print time in hours and minutes, straight from your slicer.
- Set your filament – spool price and spool weight, plus a supports allowance if the slicer weight does not already include it.
- Add electricity and risk – pick your printer for average power, choose your country or type your price per kWh, and set a realistic failure rate.
- Read the cost – the estimated cost per print updates instantly, with a full breakdown of material, electricity, wear and failure buffer.
Frequently asked questions
How much does it cost to 3D print something?
For a typical 100 g PLA print of about 5 hours, filament and electricity together usually cost well under one euro. This calculator also adds supports, printer wear and a failure buffer, so the real cost per print for most desktop FDM prints lands between a few cents and a couple of euros, depending on size, material and your energy price.
How do I calculate filament cost per print?
Divide the spool price by the spool weight to get the price per gram, then multiply by the part weight. A 25 EUR spool of 1000 g works out to 0.025 EUR per gram, so a 100 g print uses 2.50 EUR of filament. The calculator does this for you and can add a supports allowance on top.
How much electricity does a 3D print use?
Multiply the printer average power in kilowatts by the print time in hours, then by your price per kWh. A 120 W printer running 5 hours at 0.39 EUR per kWh uses about 0.23 EUR of electricity. For most FDM prints the power cost is only a few cents.
Should I include printer wear in the price?
If you sell prints, yes. Divide the printer price by its expected lifespan in hours to get an hourly wear cost, then multiply by the print time. It is optional here and switched off by default, but it matters for accurate pricing on a machine that runs a lot.
Why add a failure rate?
Some prints fail from warping, clogs or poor adhesion, and the wasted filament and time still cost money. A failure buffer of around 10 percent spreads that risk across your successful prints, so your average cost per print stays realistic.
What is a fair price per kilogram of PLA?
Standard PLA usually costs between 15 and 30 EUR per kilogram from the main brands. Silk, matte, PETG and ASA filaments cost more. Enter your actual spool price for the most accurate result.
Does this work for PETG, ABS and other filaments?
Yes. The cost math is the same for any FDM filament, so just enter the spool price and weight for the material you use. Heavier prints use more grams, which the part weight input already accounts for.
