PETG (Polyethylene Terephthalate Glycol-modified) is a thermoplastic widely used in 3D printing, combining the ease of use of PLA with the durability of ABS. Below are its core features and application guidelines:
High Strength & Flexibility
Higher impact resistance than PLA, strong interlayer adhesion, and resistance to cracking.
Chemical Resistance
Withstands oils, weak acids/alkalis, suitable for industrial environments.
Low Shrinkage
Minimal warping during printing; no enclosed printer required.
Transparency & Surface Finish
Can produce semi-transparent models with a glossy surface.
Food Safety
Some certified grades comply with food-contact standards (verify product specifications).
Nozzle Temperature: 220–250°C (adjust per brand)
Bed Temperature: 70–85°C (use PVP adhesive on glass beds)
Print Speed: 40–80 mm/s (first layer ≤30 mm/s)
Cooling Fan: 30–50% speed (full speed may cause layer separation)
Functional Prototypes: Gears, hinges, and mechanical parts requiring wear resistance.
Outdoor Equipment: Planters, lamp covers (UV-resistant grades recommended).
Containers: Water bottles, storage boxes (ensure food-grade compliance).
Electronics Enclosures: Better heat resistance than PLA, ideal for heat-dissipating designs.
