About 3D printer running costs
A 3D printer’s heated bed and hot end create changing power demand. Average draw varies by material, bed temperature and print duration.
Typical sizes: 100 W, 200 W, 350 W, 500 W.
How to spend less: Use the printer’s measured energy or power-monitor data for a precise job estimate.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Illinois. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
