Prusa Prusament PETG Jet Black 1.75mm 1kg

Prusament PETG is Prusa's own in-house filament. The entire manufacturing process is meticulously monitored and tested – Prusa guarantees an accuracy of ±0.02 mm (±0.03 mm for blends) and highly consistent colors. You can view the parameters of every spool Prusa has produced at prusament.com. Check out the sample spool!

Manufactured by Josef Prusa
Prusa wasn't satisfied with the quality of filaments on the market. So the Czech company decided to manufacture its own! Prusa Research is the only 3D printer manufacturer with its own filament production.

Premium-quality material and rigorous testing
The entire manufacturing process is meticulously monitored and tested – string diameter, color consistency, and mechanical properties – to ensure that every spool is perfect.

±0.02 mm guaranteed manufacturing precision
Prusa believes that the industry standard of 0.05 mm isn't sufficient for perfect 3D printing. Instead, Prusa guarantees ±0.02 mm precision (±0.03 for blends) and highly consistent colors in Prusament filaments.

About PETG

PETG is one of the most commonly used filaments. Its strength and durability make it an excellent choice for printing various mechanically-stressed parts, such as various holders, or clamps, for example. Due to its excellent layer-to-layer adhesion, PETG prints are ideal for indoor and outdoor waterproof applications. Furthermore, PETG is a tough material with good high-temperature resistance. The G in the acronym stands for a glycol-modified substance that is present during the manufacturing process. It modifies the properties of PET, so that it’s easier to print, less brittle, and clearer when printing with semi-transparent variants. PETG has a low thermal expansion, so even when printing big objects, and without an enclosure, it rarely lifts from the bed and warps. In addition to that, PETG is tougher and less brittle than PLA. It has a healthy amount of flex which can prevent parts from breaking under pressure. We use PETG to print parts for our printers!
