Polyethylene terephthalate glycol (PETG or PET-G) is a thermoplastic polyester. It provides significant chemical resistance. It is durable and has excellent formability for manufacturing. IIID Max Crystal PETG can be easily vacuumed. It can be pressure-formed as well as heat bent. PETG has low forming temperatures. PETG is popular for consumer and commercial applications. It is used for 3D printing and other heat-forming manufacturing techniques. This material combines the ease of use of PLA and the strength of ABS. It is FDA approved, and its strength is much higher than the PLA. It is also well known for its bridging and its clarity. PETG is one of the best products out there for 3D printing.
