PETG is another favorite 3D printing materials among users. To know its characteristics, we will compare this compound with the other two most used materials in the 3D printing industry, PLA and ABS.
One of the properties of this plastic derivative is its temperature resistance , it supports a little more than PLA, but less than ABS. It begins to soften at 80ºC, while PLA does it at 70ºC and ABS at 105ºC.
As for resistance, the PETG resists shock and effort better, making it the most difficult to break. In addition to having better theoretical properties than ABS , the higher adhesion of the layers makes PETG parts even more resistant in practice. Speaking now of its rigidity, it is less rigid than PLA and ABS, but in this case the difference with ABS is minimal.
Other interesting facts about this compound, is that is approved by the FDA (the US agency that regulates food, medicine and cosmetics) for food use. In addition, it is very stable and chemically resistant to the attack of acids and bases.
