TINMORRY PETG-CF is a 1.75 mm carbon fiber reinforced PETG filament on a 1 kg spool in Carbon Blue. The chopped carbon fiber adds stiffness and a matte, textured look compared with plain PETG, which is tougher but more flexible. It prints hotter than standard PETG, at 240-270 °C with a 75-90 °C bed, and needs a hardened steel nozzle because the fibers wear brass. It suits makers printing structural brackets, jigs, drone parts and cosplay pieces who accept a stiffer, more brittle part and a higher nozzle temperature.

This is a 1.75 mm PETG carbon fiber filament in carbon blue, sold on a 1 KG spool. It is a composite of PETG and 15% professionally processed short-cut carbon fiber masterbatch, not carbon fiber powder. The formula reduces nozzle clogging and clumping compared with traditional PETG and has good Z-adhesion.
The filament is lightweight and durable, and suits parts that need torsional, tensile and impact strength, such as drone parts, racing models and functional parts. It prints with almost no warping on Bambu FDM printers. It supports high-speed printing at up to 300 mm/s.
Because it contains real carbon fibers, it needs a wear-resistant steel nozzle of 0.4 mm or larger (0.6 mm is better), not a conventional brass nozzle. For stronger Z-adhesion, use a higher infill density and an enclosed printer, and lower the fan percentage to avoid overcooling. Wear protective equipment when cutting, sanding, grinding or sawing printed parts, as this creates carbon fiber dust.
