3D Printer Electricity Cost Calculator
Estimate what a print costs to run. Most desktop FDM printers draw far less power than people expect — this tells you the real number for your machine and rate.
How this is calculated
Energy used is average watts × hours ÷ 1000 (giving kilowatt-hours), and cost is that energy times your per-kWh rate:
cost = (watts × hours ÷ 1000) × rate per kWh
The key word is average draw. A printer's heated bed and hotend pull a lot during warm-up, then cycle on and off during the print, so the average over a job is well below the nameplate maximum.
Typical average power draw (FDM)
| Printer type | Typical average |
|---|---|
| Small printer, no heated bed | 50–80 W |
| Common desktop, heated bed ~60 °C | 100–150 W |
| Large-bed / enclosed, high-temp materials | 150–300 W |
Measuring with a cheap plug-in energy meter gives you the exact figure for your machine.
