In general, filaments made with PET CF (pet carbon) can be processed using conventional 3D printers with FDM/FFF technology. PET CF is a carbon-fibre-reinforced material developed for use in 3D printing. To ensure optimal results, it is recommended that filaments be pre-dried at 120°C for 4-6 hours. For spools weighing up to 1 kg, please increase the drying time accordingly. It is important to ensure that the filament is not left stopped inside the nozzle for more than 20 minutes. Should the temperature fall below 210°, it would be advisable to halt the thermal control. The suggested print set is intended as a recommendation for general use. Each printer requires a specific set of parameters to function correctly, including but not limited to nozzle and bed temperature settings. The minimum diameter of the nozzle with carbon fibre reinforcement is 0.5 mm. Carbon fibres are known to be abrasive, so we would suggest using a nozzle in hardened or tempered metals, such as Widia, or wearing-resistant internal surfaces, such as ceramics and other materials. I am pleased to inform you that the surface has not been treated with Teflon. Weight: 0.75 kg.
