PET / PETG
PETG (polyethylene glycol terephthalic acid) filament is a popular material for 3D printing. It has similar mechanical properties to PLA, but is more resistant to heat and moisture. It is also more flexible than PLA and ABS, making it a popular choice for applications that require flexibility. In addition, PETG is considered a safer choice for items that will come into contact with food or beverages. It is easy to print with the right extrusion temperature and print speed. However, it can be more difficult to paint and polish than PLA and ABS.
