Filament Guide A

Prusa PETG Filament Guide A is a premium 3D printing material based on polyethylene terephthalate modified with glycol. This filament combines the ease of use of PLA with the durability and heat resistance of ABS. PETG offers high toughness, chemical resistance, and good UV stability, making it ideal for functional parts. Recommended print settings include a nozzle temperature of 230–255 °C and a bed temperature of 75–90 °C. An enclosed build chamber is optional but beneficial for large prints to reduce warping. PETG has low shrinkage but tends to string, requiring retraction adjustments. Its smooth surface makes it suitable for mechanical parts, containers, and outdoor applications. With a density of approx. 1.27 g/cm³ and a 1.75 mm diameter, it ensures precise extrusion. Compared to PLA, PETG is more flexible and heat-resistant but slightly more challenging to print. Avoid excessive cooling to prevent layer separation. This filament is an excellent choice for durable, stress-resistant prints.
