As a 3D printer filament, PETG (polyethylene terephthalate glycol-modified) combines the advantages of popular materials such as PLA and ABS. PETG is easy to work with and produces strong, durable objects.... Better yet, the lack of noxious fumes lets you use unventilated 3D printers without worrying about kids or pets.
Provided your 3D printer has a heated bed, PETG filament is a great choice for general-purpose 3D printing. The material is stronger and less rigid than PLA which makes PETG objects more durable. Although ABS offers similar benefits, PETG 3D printer filament is easier to work with. Having an enclosed print volume for PETG temperature control, for example, is less important since PETG does not contract as much during cooling. It also comes in a variety of colors including our silver PETG filament.
Most printers support the nozzle and bed temperatures PETG filament requires. However, you do need to watch for PETG material behavior. When melted, it is less viscous than other thermoplastics which could lead to oozing while printing. Dialing in retraction, bridging and other slicer settings will address most issues when printing PETG, but the final object may need post-processing to remove the remaining artifacts.
The medical and food industries often use PETG plastic to package their products. The lightweight material is strong, durable and flexible which makes it ideal for protecting the enclosed products. For the same reasons, PETG filament is used for objects such as smartphone cases that must withstand the knocks and dings of everyday use.
