3D printers are becoming more prevalent in both homes and businesses. There is some worry regarding whether they are completely human-friendly. After all, 3D printing using fused deposition modeling (FDM) involves the melting of plastic. This calls into question the safety of 3D printing as well as long-term exposure to 3D printer fumes.

In this post, we'll look at the numerous health issues raised by 3D printing. Our next step will be to examine the safety of the various filaments. Then, we'll go over how to reduce the risks of utilizing a 3D printer. The purpose of this essay is not to scare you away from 3D printing but rather to make you more aware of the risks and protective precautions you can take.

Is it really that bad? Let's dig deeper and find out.

What are 3D Printer Fumes?

When a 3D printer is in use, it releases fumes containing plastic, metal, and other material particles. 3D printer emissions are made up of two types of ingredients: UFPs and VOCs. When you are not wearing the correct safety equipment, ultrafine particles (UFPs) can cause inflammation inside the eyes and nasal passages.

Volatile Organic substances (VOCs) are a class of substances that are emitted by certain solids and liquids. According to an EPA article on indoor air quality, some of these are not toxic and have a pleasant odor, while others can have negative short- or long-term health consequences. You should take precautions to avoid long-term exposure to VOCs and UFPs.

Inhaling large build volume 3D printer gases into the lungs can lead to respiratory disorders and other health complications. These gases might also cause eye irritation. When they are absorbed via the skin, they can cause skin irritation and other problems.

How to Avoid Inhaling 3D Printer Fumes?

Ventilation! The simplest way to avoid this issue is to locate your printer in a well-ventilated environment. To avoid being imprisoned in a room filled with 3D printing fumes, set up your printing environment in a place like your garage or tool room.

Do not be concerned if you do not have a garage or an outdoor spot where you can relocate your printing setup. You may easily install air cleaners, purchase and install air extractors, and build an outdoor structure to ensure that the air in your workstation is less harmful and more ventilated.

Safety Tips to Reduce 3D Printing Fumes

Use only safe filaments.

The brand of filament you purchase is critical, but so is the type of filament. If you buy an ABS-based fiber, you run the danger of breathing hazardous vapors. Stick to non-toxic fibers like PLA and PETG, which emit a few harmful scents.
Remember to use an enclosure.

Although an enclosure prevents toxic odors from permeating the air, you should still take extra measures. Cover the base of a printer with a plastic encasement before using it.

Check the air quality in your room.

When heated, filaments can produce gas, so make sure the space is well-ventilated before printing. When printing with a polymer, off-gassing is conceivable. Fresh air circulates around the space, preventing odors from collecting.

Every day, clean your 3D printer.

It is critical to undertake printer maintenance daily. A well-maintained 3D printer operates more efficiently and emits fewer odors. Remove any dust and debris that may have become airborne during operation. If you're not sure where to begin cleaning, start with heat sources like the hot end and 3D printer bed.

Store 3D Filaments Correctly

Properly store your 3D filaments. Moisture, dust, and particles from the environment can be picked up by improperly stored filament. When printing, these impurities will be heated alongside the filament. Keep them away from the sun and other heat sources.

Toxic fume exposure from a 3D printer can occur accidentally, and you must follow these safety recommendations every time to avoid inhaling 3D printer fumes. It's time to look for a wider range of non-toxic 3D printer filaments.
