PETG is made from Polyethylene Terephthalate (PET) enhanced with glycol (hence the letter G after PET). The glycol is added to the material composition during polymerization and the result is a PETG filament that is clearer, less brittle, and easier to use than its base form of PET.
Introduction of PETG Filament
PETG is made from Polyethylene Terephthalate (PET) enhanced with glycol (hence the letter G after PET). The glycol is added to the material composition during polymerization and the result is a PETG filament that is clearer, less brittle, and easier to use than its base form of PET.
PETG filament is an excellent filament choice for printing objects that need to be sturdy, have a smooth surface, and require lower shrinkage.
PETG Filament Characteristics
1. Environmental protection and non-toxic
Corn grain extraction, no pungent taste, harmless to human body, more environmental protection; natural degradation does not
pollute the environment.
2. good gloss
Good gloss and transparency, the printed object is crystal clear.
3. Easy to operate
No warpage, can be directly printed on the hotbed free platform.
4. Good liquidity
PETG filament has high fluidity and can not block the hot end (nozzle part).
5. Wide compatibility
It is compatible with 99.99% of the FDM printers on the market, and can be used with high temperature 3D printing pen, with 11
colors.

1. Before printing, check whether the machine is normal, whether the distance between the hot bed and the nozzle is appropriate, and clean up the residue on the nozzle;
2. Confirm whether the consumables are knotted, and fix the thread head every time they are used up;
3. The printing temperature varies with the equipment. The best feeding temperature can be obtained by pre extrusion, and the printing temperature should not be too high, otherwise there will be possibility of wire drawing;
4. Some models are too small and the material cooling in local area is too slow, which leads to bad molding. It is suggested to add additional fans to accelerate cooling;
5. The common printer throat has built-in Teflon tube anti blocking design, and the printing temperature should not exceed 260℃;
6. Printing parameters are related to machine performance, model size, complexity, material characteristics, etc. to find process parameters matching with machine and materials to improve the printing effect of products.
