POLYETHYLENE TEREPHTHALATE

 

 

PET is a thermoplastic in the polyester family and is one of the most important thermoplastics due to the sheer amount produced. The PETG filament is a modified version of PET and is also known as copolyester. This improvement required for 3D printing is achieved by adding a second glycol. This makes it more durable, impact resistant and does not become brittle even after regular heating.   The PETG filament is very thermoformable. Both print and layer adhesion are very good. Elements printed in PETG can even be sterilized and are therefore also used in medical technology. In addition to its high degree of resilience and ideal mechanical properties, PETG is resistant to chemicals, flame retardant and is certified as a food-grade polymer.   Therefore, it is used both for the processing and for the packaging of food as well as in the pharmaceutical industry. In addition, this material is 100% recyclable. PETG is even said to combine the advantages of ABS (temperature resistance, durability and strength) and PLA (easily applicable) in one filament.
