Does PETG release VOCs?

The total particle concentrations were 3.88 × 1010 particles for PETG and 6.01 × 109 particles for NGEN. VOCs at very low concentrations were detected in both filaments, namely ethylbenzene, toluene, and xylene. In addition, styrene was identified in PETG.

Is PETG safe to use?

In general, PETG is a food-safe plastic that's commonly used for food containers and bottles for liquid beverages. Like acrylic and many other thermoplastics, PETG is fully recyclable. PETG is both thermoformable and vacuum-formable, and can tolerate a tremendous amount of pressure without cracking.

Things you should know about PETG



Are 3D printer fumes toxic?

Yes, 3D printer fumes can be dangerous. In the 3D printing process, the melting of plastic releases harmful particles into the air. Notably, the melting of ABS, PETG, and Nylon filaments emits particles that may induce headaches, nausea and irritate the eyes and nasal tract.

Is 3D printed PETG safe to drink from?

PLA & PETG 3D prints can be safe to for food for one-time applications, only when the proper precautions are taken. You need to use a stainless steel nozzle with no lead, and ensure the filament you use doesn't have toxic additives. Natural PETG that is FDA approved is one of the safer options.

Is PETG toxic to animals?

3D printers are indeed safe for aquariums as long as you are using materials such as PLA, Nylon, ABS & PETG. You definitely don't want to use a filament which dissolves in water like HIPS.

What filament is better than PETG?

While a difference of 15 °C may not seem like much, it's a significant enough variation that means that more printers are able to print with with PLA than with PETG. PLA is also a lot less sensitive to printing factors, such as the printing environment and imperfect slicer settings, compared to PETG.

Are ABS fumes toxic?

ABS Filament Fumes

And ABS does indeed give off a toxic chemical when heated – Styrene. In extreme circumstances, this can give you a headache, drowsiness, and feelings of fatigue. So, it's very important that if you use ABS in your 3D Printer you have your ventilation sorted.

Do 3D printers need ventilation?

While not harmful in small portions, breathing in styrene on a regular basis can be harmful to the human body. Therefore, ventilation is needed anytime the 3D printing process is initiated.

Can PETG go in the dishwasher?

PETG is dishwasher safe as it's heat-resistant and capable of withstanding the high temperatures in a dishwasher. PETG is also non-toxic and does not produce odors after being washed. Be sure to regulate the dryer setting on the dishwasher to prevent damage to the PETG.

Does PLA have toxic fumes?

While everyone knows the unpleasant odor from ABS cannot possibly be healthy to breathe in, most of us generally do not really care. However, not only ABS, but also PLA, may release toxic fumes known as VOCs (Volatile Organic Carbon).

Are 3D printers safe to use indoors?

No, it's not advised to put a 3D printer in your bedroom, unless you have a very good ventilation system with a HEPA filter. Your printer should be in an enclosed chamber, so particles don't spread out easily.

Is PETG microwave safe?

Is PETG Microwave Safe? PETG is transparent to microwaves and has a high enough heat-resistance to sufficiently deal with microwave applications. PETP is the normal plastic within the group that is used for bottles and injection molding, but PETG still holds up very well.

How do you dehumidify PETG?

One of the easiest ways to dry out PETG is by using a regular home oven. This is a quick way to get rid of any moisture build-up that your filament might have if you've left it out in the open for some time. The recommended PETG filament drying temperature is done best at 65-70°C for anywhere between 4-6 hours.

What happens to PETG in water?

PETG becomes soft and will distort with force applied at +100 °C; so generally moisture isn't a issue with PETG prints, due to application. PLA and PETG absorb moisture, but do not dissolve in water.

Does PETG need heated bed?

Printing PETG requires a heated bed at 70°C - 80°C. We generally don't recommend heating your heated bed above the glass transition temperature of PETG (80°C ). A heated chamber is not required to successfully print parts in PETG.

Can you boil PETG?

Temperature Resistance

While most PETGs can withstand temperatures of up to around 80 °C, ABS can go until 100 °C. The margin is small enough that PETG will last in most electronics applications, but only ABS will survive boiling water. This is especially useful if you need to sterilize your print.
