How we worked it out

  1. Energy per hour: 350 W ÷ 1,000 = 0.35 kWh
  2. Cost per hour: 0.35 kWh × $0.155 = $0.054
  3. Cost per day: × 20 hours = $1.09
  4. Month and year: × 30 days = $32.55, × 365 days = $396.03

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 Florida. 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.
