What is PETG filament?
PETG filament, also known as Polyethylene Terephthalate Glycol, is a co-polyester known for its durability and ease of use. The G in PETG, stands for glycol-modified, which makes the end product clear, having glass-like visual properties. It is often described as the “best of both worlds” because it has the rigidity and mechanical properties of ABS but is still easy to print like PLA.
Advantages of PETG filament
PETG is a popular 3D printing material for many reasons.
- Polyethylene Terephthalate Glycol has amazing thermoforming characteristics, meaning it is easily heated and formed to specific molds.
- PETG plastic is less likely to shrink or warp.
- Often used when transparency is important because of its glass-like quality.
