PETG (Polyethylene Terephthalate Glycol-modified) is a widely used filament in 3D printing because of its strong and versatile properties. Here are the main features of PETG filament:
Strong and Durable : PETG combines the strength of ABS with the easy printability of PLA. It is very sturdy and impact resistant, making it suitable for functional parts.
Flexibility : It is somewhat flexible, but retains its shape well under stress. This makes it less brittle than PLA.
Weatherproof : PETG is resistant to water, chemicals and UV rays, making it suitable for outdoor applications.
Good Interlayer Adhesion : The material has excellent interlayer adhesion, which ensures strong prints and less chance of breakage.
Temperature resistant : PETG can handle higher temperatures well than PLA (up to about 80°C), but its melting point is lower than ABS, around 220-250°C.
Transparency : PETG can be transparent and has a glossy finish, which can be aesthetically pleasing for certain applications.
Less Warping : Compared to ABS, PETG has less tendency to shrink or warp, which provides greater dimensional stability during printing.
Safe for Food Contact : Some PETG grades are approved for food safety, although it is important to check that the specific manufacturer guarantees this.
Odorless : PETG produces little to no odor during printing, unlike ABS.
Moderate Scratch Resistance : While PETG is quite strong, it can be more susceptible to scratches compared to materials like ABS.
Overall, PETG is a well-balanced material that is suitable for both functional and decorative applications. It offers an excellent combination of strength, flexibility, and weather resistance, making it a popular choice in the 3D printing community.
