If you are new to the world of physical printing, you may wonder how many watts do 3D printers use. Some of the best printers, after all, are 3D printers, and these models can require a fair amount of electricity to operate. So how watts do the best 3D printers require to operate, and what are some tips to reduce energy usage? Keep reading to find out.


  • 3D printers use up a fair amount of energy due to the heated bed and various moving components when making 3D prints.
  • Each printer is unique regarding energy requirements, so look for the wattage details in the instructions and pay attention to the actual cost of printing.
  • Conserve power supply energy and electricity costs by simplifying design documents and adjusting the print bed and other heating elements to a lower temperature.

How Do 3D Printers Work?

Before learning how long 3D printers take to finish objects, it is helpful to understand how these printers work with regard to energy usage. Printers extrude building materials from dedicated nozzles onto dedicated print beds if you are learning how hot a 3d printer bed should be. The nozzle builds objects layer by layer if you are wondering how small these printers can print or how to fix a problem with stringing filament.

Insider Tip

You can also conserve energy by keeping the printer properly cleaned and maintained.

The printer uses energy to heat the print bed, move the nozzles, extrude materials, access digital files, and so much more.

How Many Watts Do 3D Printers Use?

You might suspect what is coming. There are dozens upon dozens of 3D printers out there, and soon there will be hundreds. This is a fast-growing segment of the industry, so it is tough to nail down an accurate wattage for these printers, as it fluctuates greatly depending on your make and model.

Tips to Conserve Energy When Printing

Each printer is different, but there are still some universal tips to help conserve energy as you print.

Adjust the Bed

Many print beds are heated, which helps initial layers adhere both to the bed itself and to one another. This helps increase the structural stability of the finished product. However, heating up your print bed requires a fair amount of energy, and not all materials even need it. While ABS almost demands a heated print bed, PLA can get by just fine without it. Adjust the print bed temperature, or turn it off entirely, to save electricity.

STAT: One of the main operating expenses of a 3D printer is its power consumption. Without power, there won’t be any heating, motor movement, and printing, so this cost is hard to avoid. (source)

Simplify Designs

Print jobs can take a long time, as some complex objects require a full day or longer to print. Obviously, the longer a print job takes, the more electricity it eats up. You can cut down on energy usage by simplifying the design documents before hitting that print button. Look for ways to thin out walls and shrink the overall design.

Printer Wattage FAQs

So how much power does a printer use?

The watts of power required by a printer depends on the printer model itself and the size of the 3D prints being built. Some motors, like stepper motors, require more energy than others.

How to reduce the power consumption of your printer?

If you are looking to cut down on energy costs when making 3D prints, cut down on the print time itself, as this reduces 3D printer power consumption. You can also simplify design documents of 3D prints to further reduce print time.

Are these printers energy efficient?

Compared to some home appliances, they are considered energy efficient. In other words, the average cost to run a printer is lower than the electricity costs to power the heating elements of a space heater or related appliances.
