How Much Electricity Do 3D Printers Use? A Comprehensive Guide

Posted by

3D printing has become increasingly popular in recent years, with many people using it for a variety of purposes, including creating prototypes, making customized parts, and even crafting unique pieces of art. However, while 3D printing can be a fun and rewarding hobby, it’s important to consider the amount of electricity that it uses.

So, how much electricity do 3D printers use? The answer varies depending on a number of factors, including the size and complexity of the printer, the temperature at which it operates, and the duration of the print job. While some 3D printers use relatively little electricity, others can consume a significant amount of power.

Understanding the energy consumption of 3D printers can be helpful for a number of reasons. For one, it can help you estimate the cost of running your printer, which can be useful if you’re on a tight budget. Additionally, it can help you make more informed decisions about which printer to purchase, based on your energy needs and preferences. By learning more about how much electricity 3D printers use, you can make the most of this exciting and innovative technology.

How 3D Printers Use Electricity

Power Consumption of 3D Printers

3D printers require electricity to operate, and their power consumption varies depending on the model and usage. According to 3D Insider, the power consumption of 3D printers ranges from 60 W to 250 W during printing. This range corresponds to 0.07 to 0.24 kWh.

Some 3D printers require more power than others. For instance, a 3D printer that requires a 30A 12V draws a maximum of 360 watts of power. On the other hand, a printer with a hot end of 401°F (205°C) and a heating bed of 140°F (60°C) uses an average of 70 watts.

Factors Affecting Electricity Usage

Several factors affect the electricity usage of 3D printers. One of the most significant factors is the printing time. The longer a printer runs, the more electricity it consumes. The type of filament used also affects the electricity usage. Some filaments require higher temperatures, which increases the power consumption of the printer.

Another factor is the printer’s settings. For example, if the printer is set to print at a higher resolution, it will consume more power. Additionally, the printer’s cooling fan and LED lights also consume power.

Estimating Electricity Cost

The cost of electricity used by a 3D printer depends on the printer’s power consumption and the electricity rate in your area. According to 3D Sourced, you can expect to pay between $0.007 and $0.02 per hour for running a 3D printer. This translates to $0.17 to $0.48 per day and $62.05 to $175.02 per year.

In the UK, the average kWh price is £0.28. Therefore, the electricity cost of running a 3D printer for an hour ranges from £0.014 to £0.042. If you run the printer for eight hours a day, the electricity cost would be between £0.11 and £0.34 per day.

To estimate the electricity cost of running your 3D printer, you can use an online electricity cost calculator or check your electricity bill. By monitoring your electricity usage, you can adjust your printing habits to minimize your electricity costs.

Reducing Energy Consumption

Reducing the energy consumption of your 3D printer not only helps the environment but also saves you money on your electricity bill. Here are some tips to reduce your 3D printer’s energy consumption:

Choosing the Right 3D Printer

When selecting a 3D printer, consider its energy efficiency. Some 3D printers are designed to consume less energy than others. Look for 3D printers with energy-saving features such as automatic shut-off and power-saving modes. Also, consider the size of the printer. Larger printers tend to consume more energy than smaller ones.

Using Energy-Efficient Settings

Another way to reduce energy consumption is by using energy-efficient settings. Most 3D printing software allows users to adjust settings such as layer height, infill density, and print speed. Using lower settings for these parameters can reduce the amount of energy your printer consumes. Additionally, consider using filament made from biodegradable materials such as PLA, which requires less energy to process than other materials.

Other Tips for Saving Energy

Here are some other tips for saving energy while 3D printing:

  • Print multiple objects at once to reduce the amount of time your printer spends idle.
  • Use a timer to schedule prints during off-peak hours when electricity rates are lower.
  • Keep your printer in a well-ventilated area to prevent it from overheating, which can cause it to consume more energy.
  • Turn off your printer when not in use to prevent unnecessary energy consumption.

By following these tips, you can reduce the energy consumption of your 3D printer and save money on your electricity bill.


In conclusion, 3D printing is an exciting technology that has revolutionized the way we create and manufacture objects. However, it is important to consider the amount of electricity that 3D printers consume during operation.

Based on the research, the average 3D printer uses between 50 and 150 watts of electricity per hour. The actual amount of electricity used depends on several factors, such as the size of the printer, the temperature of the printing bed, and the duration of the print job.

It is worth noting that 3D printers do consume a significant amount of electricity. However, the cost is not as high as one might think. On average, you can expect to pay around $0.10 per hour for electricity. The actual cost will depend on the type of 3D printer you have and how much electricity your region charges.

To reduce the amount of electricity that your 3D printer consumes, you can take several steps. These include:

  • Using energy-efficient 3D printers
  • Printing at lower temperatures
  • Reducing the size and complexity of your prints
  • Turning off your printer when it is not in use

By implementing these measures, you can reduce your electricity consumption and save money on your energy bills.

In summary, while 3D printing is an exciting technology, it is important to be mindful of the amount of electricity that it consumes. By taking steps to reduce your energy consumption, you can enjoy the benefits of 3D printing while also being environmentally conscious and saving money.
