What causes 3D Printer fires?

Hazards are part of every technology; when the wheel was invented, wheels had operational hazards, too; someone could get run over by the wheel. 3D printing technology is no exception to this fact and has hazards such as poisoning and even fires associated with it.

3D Printer fires

On occasion, 3D printers have been known to catch fire. In the most recent incident, a 3D printer in a Wisconsin school caught fire in March of this year and cost over $100,000 to repair. The extruder, the component of the printer that melts the plastic filament required to construct the 3D item, was the source of the fire. A blocked ventilation system or a malfunctioning cooling system is only a couple of the causes of this heat buildup.

The use of 3D printers is growing, particularly in the field of education. It's conceivable that there will be more fires started by 3D printers as technology advances. People throughout the world use 3D printers in great numbers. Generally speaking, one should use caution when operating a 3D printer owing to the possibility of setting it on fire.

Manufacturers of 3D printers frequently make it clear that they should never be left unattended. If one is present, stop using the printer as soon as a problem arises. It's possible for a 3D printer to overheat. The frame of the printer is the most hazardous component of the device unless it is constructed of metal. The printer should have at least one fan, and an additional one can be added to facilitate cooling. Make sure everything needed to put out a fire is available when there is one and that the fire has been put out.

Common workplace printers have a weakness that allows hackers to take control of them and use them to spy on users, transmit malware, and even set them on fire. This was found by researchers at Columbia University in New York. Due to this, it's critical for anyone who uses 3D printers to be aware of the dangers and take preventative measures to minimize them.

What are the factors that cause 3D Printer fires?

  1. Overheating: The majority of fires that are caused by 3D printers are electrical in nature and start when the insulation on the wires inside the printer melts due to excessive heat. When this occurs, the cables may transfer heat to the 3D printer, melting the frame, filament, or structural parts, and ultimately igniting the machine from within. A poorly built printer is to blame for most electrically-related 3D printer fires. There is a good risk that printers with loose solder, poorly insulated connections, and improperly sized wires may catch fire eventually. This means that the easiest method to prevent fires is to make sure your 3D printer is built properly or to get a printer from a recognized brand.
  2. Loose Thermistor: The plastic filament is heated during the printing process so that it becomes a liquid. The filament is then forced out by the extruder, resulting in a layer of printed material. In order to prevent warping and regulate the rate at which the filament cools down, some 3D printers also employ a heated print bed. As a result, the printer will continue to heat up whenever it is printing anything. Thermistor temperature reading technology is used in the printer to control temperature and prevent filament burning. Thermistors connect with the printer's electronics to regulate the amount of heat it emits while utilizing a sensor to read the temperature. To connect to the control boards of your printer, they employ cables; however, these connections are infamous for coming undone. They are also screwed to the printer. The printer won't accurately estimate the heat level when the connections are loose, which could cause overheating or a fire if the user doesn't manually shut off the printer and fix it.
  3. Thermistor malfunction: Thermistors could also be faulty in terms of their sensitivity to the temperature. The sensors may not be working properly, or the component that controls the temperature might be unable to control the temperature accordingly. The end result is overheating, which proceeds to damage the electrical components, which could lead to sparking and short circuits.
  4. Malfunctions of the thermal runaway: The majority of the acrylic and plastic components utilized in 3D printer construction, including filament, are highly flammable. The casing, filament, or other parts of the printer could melt and eventually catch fire if the heat is allowed to rise unchecked. Because of this, most 3D printers have a thermal runaway feature that turns the printer off if it becomes too hot. If the thermistor malfunctions or becomes loose, the thermal runaway safety mechanism prevents the 3D printer from catching fire. Flames will undoubtedly result if the thermal runaway is manufactured improperly or cannot detect the thermistor's heat level.
  5. Blockages in the extruder: As the model prints, the warm extruder will move, depositing thin layers of melted filament onto the print bed. The extruder uses heat to construct the sculpture, but if it doesn't have time to cool between layers, it might pose a serious fire risk. The extruder, however, could be blocked and kept stuck in one place on the printed model if the print fails and prevents the extruder from moving correctly. When this occurs, the extruder may heat the model to the point that it begins to melt and catch fire. This can also be owed to the property of the filaments, which are flammable in nature.
  6. Printer casings that are flammable: High-quality thermal printers can be pricey, but they are typically justified given how frequently printers constructed of inexpensive, flammable materials catch fire during printing. When it comes to holding all the parts together, materials like foam, acrylic, plastic, and wood are appropriate for the 3D printer's structural components. However, using the printer while using these combustible components significantly increases the likelihood that it will melt into a hot mess.
  7. Operating the 3D Printer overnight: Whether it is safe to leave a 3D printer running overnight depends on a variety of things. The kind of 3D printer you have is the most crucial variable. It is not advised to keep a cheaper, lower-quality 3D printer running overnight since it could overheat and catch fire. It is generally safe to leave a 3D printer running overnight if it is of better grade and was created for industrial use. The substance you are printing on is another aspect to take into account. For overnight printing, some materials, including PLA, are not advised since they may release toxic gases. Letting a 3D model created in a 3D modeling software print overnight is one of the simplest ways to speed up the printing process. The great majority of printers are not made to operate independently. In addition, 3D printers are recognized to be fire hazards. By using some management and risk-reduction measures, you can lower your risks. Poorly constructed 3D printers may have loose thermistor sensors that cause them to overheat and start a fire. Cables may eventually become brittle and melt due to the strain. A fire could also start from an electrical short in a wire. A printer should never be left unattended. Octoprint offers camera feeds, status updates, and G-Code visualizers in addition to remote monitoring. This tool enables you to keep an eye on, manage, and turn off your 3D printer if it begins to operate outside of predetermined parameters. A thermistor that is misplaced, loose, or ineffective is frequently the root of thermal runaway. The thermal runaway protection feature on 3D printers is turned on by default. A smoke detector can be a smart option if the 3D printer will be used overnight. A printer can overheat and catch fire if it is left unattended for a long time. Printers can become very dangerous if live cables or hot mattresses are left inside. Although 3D printers are a great tool for swiftly and easily producing products, they shouldn't be left alone for very long. If the printer must be left for an extended amount of time, it is essential to monitor it and make sure it doesn't overheat.

How to prevent fires while 3D Printing?

  • Never leave the printer unattended for prolonged periods while operating the printer. Lack of attention will lead to mishaps being undetected.
  • Install a smoke sensor; it will give an early warning in case a fire starts.
  • Check the condition and quality of the wiring frequently.
  • Do not operate the printer for prolonged periods.
  • Carry out periodic servicing.
  • Install monitoring systems.
  • Keep fire extinguishing equipment ready.

Print smartly and responsibly

Although there are several factors that lead to 3D printers catching fire, they all boil down to one reason which is the lack of monitoring. Most of these accidents can be avoided if the process is monitored adequately. When someone is monitoring the process, it is easier to take note of any malfunctions or mishaps, and it is easier to take necessary action. Being prepared to handle fires, installing monitoring software or devices, and keeping fire extinguishers ready would help stop fires. But as always, prevention is better than cure. If you are on the lookout for a program to create your designs, we recommend using SelfCAD. This is an easy-to-use 3D modeling software that allows you to not create 3D designs, but also preparing them for 3D printing without having to switch to a different program.
