3D Printer Catching Fire

If you spend enough time online, you will come across someone’s picture of their 3D printer catching on fire. People want to know if this is something that is common and whether or not they are in danger if they have one of these printers. 

There are a lot of 3D printers that are being used all over the world, and it is easy to get caught up in those that have problems. Although it is a rare occurrence, it is possible for a 3D printer to catch fire, and you need to exercise safety precautions when you are using one. 

Can 3D Printers Catch on Fire?

3D printers can catch on fire. In fact, most manufacturers recommend explicitly that you not leave the printer running unattended. This type of fire will start in the machine, and it can spread through the room and then to the rest of your home.

It is important to make sure that you operate your 3D printer safely to limit any potential damage from a fire. If you are there, you can turn the printer off at the first sign of trouble. That said, it is not common for it to catch fire if it is used and maintained properly and if you pay attention when it is operating. 

How Long Should a 3D Printer Run?

If you maintain your 3D printer properly, it doesn’t need a break, and it can print for days without any issues. However, there are some factors that can limit how long it should run. The problem is that it takes a long time to print larger models

If you plan to run your printer for an extended period of time, you should find out if it has thermal runaway protection. This protection prevents temperatures from rising too much and causing a fire. The firmware in the printer will check readings on the thermistor and stop printing if it notices any abnormalities. 

What Can Cause a 3D Printer to Catch on Fire?

Most of the time, 3D printer fires are electrical fires. This happens when the electric currents and the heat build up in the wiring. This type of fire can easily spread throughout a room and then the entire house. 

It is important to make sure that you have wires, insulation, and connectors that are flame retardant so that this is less likely to happen. The frame is the most flammable part of the printer, unless it is made of metal. However, those made of acrylic are more susceptible to fire. 

Can 3D Printers Overheat?

It is possible for a 3D printer to overheat. It usually happens when you are printing an object where the layers get smaller, such as when you print a tower that tapers at the top. The best way to prevent this is by cooling each layer. You should have a fan in your printer, and you can add another one to make it easier to cool. You can also try lowering the temperature, or you can lower the speed or the printing process. 

How Many kWh Does a Printer Use Each Day?

The average 3D printer uses 0.05 kWh for one hour of printing. This is a very low amount of electricity. However, you should check your 3D printer’s power rating. If it requires a 30 12 V, it draws up to 360 watts of power. This is the maximum, and not the actual amount of power it draws.  

Is it Safe to Leave a 3D Printer on Overnight?

You should be careful if you plan to leave your 3D printer on overnight. There are dangers, such as the printer overheating and catching fire. Other problems can happen, such as prints detaching from the surface or the nozzle getting clogged. 

Is it Safe to Operate a 3D Printer at Home?

It is safe to operate a 3D printer at home as long as you pay attention to it while it is operating. Don’t leave it unattended, and make sure that you have everything you need to put out a fire if one starts. 

Tips for Safety

  • Keep a fire extinguisher nearby
  • Use a 3D printer with a metal frame
  • Don’t leave the 3D printer unattended

Final Thoughts

A 3D printer can catch fire, but if you are attentive and take proper precautions, you can safely use one at home.
