PETG is a Glycol Modified version of Polyethylene Terephthalate (PET) - It is a semi-rigid material with good impact resistance, but it has a slightly softer surface which makes it prone to wear. The material also benefits from great thermal characteristics, allowing the plastic to cool efficiently with an almost negligible warpage. 

The dimensional accuracy of FuseForm PETG is +/- 0.02mm. Printing temperature range is 210°C - 250°C (410°F - 482°F). Printing on a heated bed is recommended at 60°C - 70°C. Speed 20-100mm/s is recommended as a starting point and fine-tune to suit your printer. 

Currently, there are only a limited color options for PETG but in the coming future, Fuse Form will offer more color options.
