3D Printer Electricity Cost Calculator

Estimate monthly and annual electricity cost for FDM or resin 3D printing, including idle/standby power and (for resin) UV cure station time.

کب استعمال کریں

Use this to budget the ongoing electricity cost of a hobby 3D printing setup, or to compare the running cost of an FDM printer against a resin printer with a UV cure station.

موازنہ

Unlike a rough per-print cost estimate based on wattage alone, this calculator separately tracks printing, curing, and standby energy across a full month, which better reflects printers that sit plugged in and idle for most of the day.

Enter your values below. Calculations run locally as you type.

یہ کیسے کام کرتا ہے

Printing energy is your printer’s average running wattage converted to kWh, multiplied by hours per print and prints per month.

Idle/standby energy is calculated separately from the wattage the printer draws while powered on but not printing, since many printers stay plugged in for far more hours than they actually print.

For resin printers, UV cure station energy is added per print based on its wattage and cure time, then everything is multiplied by your electricity rate to get monthly and annual cost.

اکثر پوچھے گئے سوالات

How much does standby/idle power actually cost over a month?

A printer left plugged in and idle at 5W for 16 hours a day uses about 2.4 kWh a month — a few dollars at most residential rates, but it adds up over a year, especially for printers that stay on between prints.

Does resin printing use less power than FDM?

Often yes for the print itself, since resin printers have no hotend or heated bed to maintain — but you also need to add the UV cure station, so total power draw per print can be similar once curing is included.

Does the UV cure station meaningfully add to the electricity bill?

Usually only a small amount, since cure times are short (often under 20–30 minutes per print). It is a much smaller contributor than the printer itself or standby time across the month.

عملی مثال

ان پٹ

FDM printer at 120W, 8 hrs/print, 20 prints/month, 5W idle for 16 hrs/day, $0.16/kWh.

آؤٹ پٹ

Printing: 19.2 kWh/mo. Idle: 2.4 kWh/mo. Monthly cost: about $3.46 ($41.47/year).

Printing uses 19.2 kWh a month (0.12 kW × 8 hrs × 20 prints). Idle standby adds another 2.4 kWh a month even though the printer is not actively printing most of the day. Combined, that is about $3.46/month or roughly $41.47/year at $0.16/kWh.

عام غلطیاں

  • Ignoring idle/standby power understates the real bill — many printers stay powered on far more hours per day than they spend actively printing.
  • Forgetting the UV cure station on a resin printer misses a real, if usually small, part of the total electricity cost.
  • Using a printer’s peak wattage instead of its average running wattage overstates cost, since most printers do not run at peak draw for the entire print.
