Prusament 3D Printer Filament PETG Anthracite Grey 1.75mm - 1kg Spool - High Precision ±0.02 mm - Low Stringing - Strong Layer Bond - No tangling - Ideal for Beginners & Professionals

We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production. The whole manufacturing process is closely monitored and tested - string diameter, color consistency, and mechanical properties - to make sure that every spool is perfect. We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.02mm precision and highly-consistent colors in our filaments. We are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online. 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! Printing Setup: Nozzle 250 ±10 °C Heatbed 80 ±10 °C Recommended Steel Sheet Textured / Satin Unlike PLA or ABS, PETG tends to ooze a bit and may leave strings of plastic on your print. We suggest drying the filament before printing, as described here. If stringing still occurs, you may further counter it by increasing retraction and playing with hotend temperature, but if you use our filament presets in Prusa Slicer, we already did that for you and the amount of stringing should be minimal. Or, you can get rid of the strings by briefly blasting your finished prints with a heat gun.
