3D printing has become an increasingly popular hobby and profession in recent years. While 3D printers offer endless possibilities for creating objects, it's important to remember that they are electrical appliances that require proper safety precautions to avoid accidents. In this article, we will discuss some electrical safety tips to help you stay safe while 3D printing.

  1. Inspect your printer regularly

It's important to inspect your printer regularly for any signs of damage or wear and tear. Check the power cord, heating element, and other components to make sure they are in good condition. If you notice any issues, stop using the printer immediately and have it repaired by a professional.

  1. Use a surge protector

A surge protector can protect your printer from electrical surges and prevent damage to the printer or your home's electrical system. Plug your 3D printer into a surge protector to protect it from power spikes and surges.

  1. Keep liquids away from the printer

Spills can cause electrical shock or damage to the printer. Keep liquids such as water, coffee, or soda away from the printer and the electrical outlet to prevent any accidents.

  1. Use a GFCI outlet

A Ground Fault Circuit Interrupter (GFCI) outlet can prevent electrical shock and fire hazards by detecting and interrupting electrical faults. Use a GFCI outlet in the area where your printer is located to reduce the risk of electrical hazards.

  1. Avoid using extension cords

Extension cords can be a safety hazard as they can overheat and cause a fire. Instead of using an extension cord, position the printer near an electrical outlet or have a qualified electrician install an outlet closer to the printer.

  1. Use a fire extinguisher

In case of a fire, keep a fire extinguisher nearby and make sure you know how to use it. A Class C fire extinguisher is suitable for electrical fires, which are common in 3D printers.

  1. Do not touch the printer while it's printing

Avoid touching the printer while it's printing, especially the hotend or the heated bed. They can reach high temperatures and cause burns or electrical shocks.

  1. Unplug the printer when not in use

When you're not using the printer, unplug it from the electrical outlet. This will prevent any accidental electrical shocks or damage to the printer from power surges.


In conclusion, 3D printing can be an exciting hobby or profession, but it's important to remember that safety should always come first. By following these electrical safety tips, you can reduce the risk of accidents and protect yourself, your home, and your 3D printer. Remember to read the manufacturer's instructions carefully, and if you have any questions or concerns about the safety of your printer, consult a professional.
