How much does a 3D Printer cost to run?

Based on typical usage

A 3D Printer typically uses about 250 watts, costing around $0.04 per hour at $0.15 per kWh.

At typical use (3 hours per day), that's about $3.37 per month and $41.06 per year.

Per hour $0.04
Daily $0.11
Monthly $3.37
Yearly $41.06

Based on

  • 250 watts
  • 3 hours per day
  • $0.15 per kWh

What affects cost most

  • Average hours used per day
  • Electricity rate in dollars per kWh
  • Performance mode, accessories, and idle time between tasks

How it works: Daily cost uses wattage, hours per day, and electricity rate. Monthly uses daily × 30; yearly uses daily × 365.

Use the calculator below to estimate cost based on your own wattage, usage time, and electricity rate.

Get a better estimate and keep costs down

Defaults are a starting point. Real cost changes most when runtime, wattage, and your electricity rate differ from the benchmark assumptions.

What changes cost most

  • Average hours used per day
  • Electricity rate in dollars per kWh
  • Performance mode, accessories, and idle time between tasks

How to get a better estimate and lower cost

  • Replace the default electricity rate with the actual rate from your latest power bill.
  • Adjust daily runtime to match how long you actually use the equipment.
  • Group prints to reduce repeated bed warm-up cycles.
  • Use efficient print profiles when high detail is not required.
  • Insulate the printer enclosure if compatible with your setup.
  • Turn off accessories and lights when not needed.
