Polyethylene Terephthalate (PET) is the most commonly used plastic in the world. In 3D printing we use PETG, the "G" stands for Glycol, an additive which makes the material easier to print and increases its clarity. PETG is a great choice for many applications as it can be as strong as ABS, can be optically clear, has flexibility and is highly impact resistant.
Ease of Use
Start print at 245°C and on the third layer, lower it to 235°C.
Prints better with no cooling fan.
Use a heated bed or GeckoTek cold to print.
Slow printing is recommended.
