Was ist G PET?

What is PETG used for?

It is widely used for packaging (both retail and medical), advertising displays and electronic insulators. It is also widely used in 3D printing since the glycol prevents the problems associated with PET, such as overheating and becoming cloudy and fragile. It is also possible to sterilise PETG items.

Is PETG plastic safe?

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.

What does PETG plastic stand for?

Polyethylene terephthalate glycol

PETG or Polyethylene terephthalate glycol is a thermoplastic polyester commonly used in manufacturing.

What is PETG vs PET?

PET is the result of two monomers combining. PETG may involve these same monomers, but also includes glycol, giving it different chemical properties than PET. This means that PETG has better shock resistance and is better suited to higher temperatures.

Does PETG crack easily?

If you're transitioning to PETG from PLA, you may find that PETG cracks rather easily. While PLA benefits from large amounts of cooling, PETG can suffer if it's cooled too quickly. If print layers begin to separate or crack, reduce the fan speed.

How toxic is PETG?

As a raw material, PETG is considered food-safe. This means that there are no toxic chemicals or ingredients in the pure polymer that will contaminate food or pose a danger to humans. That being said, there are other factors that can influence how food-safe PETG filament actually is.

What are the downsides to PETG?

What Are the Disadvantages of PETG Compared to PLA?

PETG is harder to hand finish than PLA.
PETG requires higher processing temperatures than PLA.

Is PETG safe to eat?

Kodak PETG is an easy to use material that has many benefits. It is stronger and more temperature resistant than PLA. Compared with ABS, it is just as strong but can be printed with much less warping, and without odors. Kodak PETG has been approved as food-safe by the FDA.

Is PETG cancerous?

PETG and PLA are not bad at all. They don't smell and shouldn't give off any toxic fumes. They will however give off some very small particles that probably aren't super healthy to inhale but nevertheless a lot of people, including myself, print PETG and PLA in the room we're in without any precautions.

Can PETG hold boiling water?

Temperature Resistance

While PETG's glass transition temperature is around 80 °C, ABS can go until about 105 °C. The margin is small enough that PETG will last in most electronics applications, but only ABS will survive boiling water.
