How to avoid the safety hazards caused by 3d printers?

Posted by menglisa on

3d printers emerged in the 20th century and were yield unusually brilliant results in the 21st century. While we enjoy the convenience of technology, There are security risks associated with technology. These devices can often malfunction if not assembled correctly or used without optimal aftercare. One such unfortunate incident occurred when spontaneous sparks from the device promoted its user to toss the 3D printer into the yard. Plenty of similar stories of people having equally terrifying experiences have resulted in safety hazards that need to be considered before operating a 3D printer.

The best solution is to understand how it is created, and we should work to avoid the lousy result. Next, we will elaborate on the following three sides; As machine structure, potential safety hazards are those and precautions.

We could found by search on Third-Party Platforms, LCM machines, and FDM machine reviews contents there is a big difference. Like Amazon, users who purchase LCD machines will be more concerned about printing accuracy, while FDM machine users care more about the smooth printing process.


Machine Structure

The LCD 3d printer structure comprises MONO screen, light source (lamp plate with lens), mainboard, release film, Z-Axis. And printing material used is UV Resin. The security will be higher because it is a closed structure.

Factors leading to safety hazards

The direct safety hazard comes from the UV Resin and UV Source. Usually, the device adopted a closed structure, the risk of UV lights is almost zero. Unless someone disassembles the machine because they are curious and the process is powered up, that could cause UV light to leak out. Without goggles directly to the UV, there is a risk of irreversible damage to the eyes.

When you use it to printing a model, the curing of the resin in the printed model may form UFP is because the resin printing process is cured by ultraviolet radiation to carry out a kind of solidification and produce.

What is the UFP?

It is fine nanoscale particles that are not visible to the human eye but can be absorbed by the body. E-cigarettes, car emissions, dust, heat all generate UFP. Don’t worry about UFP too much. It is safe as long as use under normal circumstances. Leare more Click Here


1 Ensure users don’t congregate near the 3D printer before running the machine to minimize the inhalation of ultrafine particles being emitted.

2 Ensure the usage of the 3D printer in a well-ventilated room or a laboratory

3 Avoid eating, drinking, chewing gum, handling contact lenses where the 3D printer is being used. Wear eye protection and nitrile gloves.

4 Wear eye protection and nitrile gloves while handling uncured printing material.

5 Set up the printer in an area without static electricity or flammable materials.

6 Once the 3D printer has been used, and you must clean all exposed surfaces with a wet method to get rid of the particles emitted into Furthermore, you must clean the extruder as it can form a jam from the abrasive Once that is done, it is also imperative that you thoroughly wash your hands with soap after you’ve cleaned up all the surfaces around the machine.

7 In taking models are usually with gloves, masks, put in a separate workshop, good airflow, and ready to clean alcohol. This practice appears to be more professional when we operate, handle the model more efficiently and keep the printing room neat and clean.

8 In addition, the resin needs to be poured into the vessel when it is used. If not used can be put back into the bottle, and continue to use it later when you need to print.

9 The aftercare of a 3D printer.

FDM 3D Printer

Machine Structure

The FDM structure mainly includes Hotend(Printing head), the hotbed, the extruder, the mainboard, the power supply, and the breakage detector. The Amazon reviews on the reasons that lead to bad reviews are mainly: heat and short circuits.

Factors leading to safety hazards

Heat are a few components of a 3D printer that present hazards for its users. For instance, the hotbed can reach the temperature, the cradle can reach the temperature of 100 °C, while the nozzle and the heating element on the extruder can go as far as 270 °C. Not just that, the motor employed by, As a result, careless operation of the machine can lead to injuries. As a result, reckless operation of the device can lead to injuries and cause third-degree burns.

According to the beginning of the mentioned, if you do not have an exemplary assembly or setup can also lead to machine failure and thus create potential problems. For example, short circuit. Let’s look at two cases

1 Error Code: The Marlin code is not set correctly, resulting in opposite positive and negative interfaces, causing a short circuit.

2 Power switch: The wiring is not firmly connected, resulting in a short circuit and burned control.


1 When you get the machine, check the packing list to make sure the parts are correct.

2 Check the condition of the device and perform a simple tune-up

3 Make sure the print file is ready to run

4 After use, place the machine at a room temperature of 20-40 degrees to avoid rust. If possible, seal the supplies

5 If you need to test the device, please power it off first.

6. Do not touch the hot part of the machine because of curiosity during the printing process to avoid burns.

3D printers possess a complicated mechanism of moving parts, coming together to bring life to your ideas seamlessly. For this reason, it is essential to mitigate negligence and ensure a safe distance from the machine before beginning the process of printing.

The introduction of 3D printers has enabled users to take a creative design from an idea and convert it into a physical, 3-dimensional prototype of the product within the printing process. However, this device can also pose severe implications to your health. For this reason, we highly recommend that you do your thorough research before deciding to begin the printing process.
