PETG

PETG (polyethylene terephthalate glycol)

The PETG material is essentially the same as the known PET material from which PET bottles are made. The G in the acronym PETG stands for Glycol which is added during the manufacturing process. Glycol modifies the properties of PET so that it’s easier to print and less brittle. It is a strong and tough material, which is characterized by good thermal stability. Thanks to the small shrinkage during printing, it is suitable for printing large objects. PETG has mechanical and thermal properties better than ABS and bearing the printing properties of PLA.

PETG is more elastic than e.g. PET, but still retains the strength and layer bonding. It has an increased tendency to make small strings when printing. Therefore, it may be advisable to increase its retraction relative to e.g. PLA.

PETG is printed at 230-250 ° C. A heated plate is needed; it should be heated to 60-80 ° C.

PETG filament is hygroscopic, which means that it absorbs moisture from the surrounding air - it is therefore recommended to store the material in a bag together with silica gel to bind any. moisture. You will get a significantly nicer print, you keep your PETG dry, possibly. with a decidedly filament dryer like this.
