PETG (Polyethylene Terephthalate Glycol) is a popular 3D printing filament known for its durability, ease of use, and versatility. It is a modified version of PET (Polyethylene Terephthalate) that incorporates glycol, which improves its impact resistance and flexibility. Here are some details and technical properties of PETG:
Material details
PETG is a modified version of PET that incorporates glycol, enhancing its flexibility and impact resistance. It has good layer adhesion and can be post-processed through sanding, polishing, or dyeing to achieve desired finishes. PETG is commonly used for functional parts, prototypes, and objects that require durability and impact resistance.
