FAQ
What hardware do I need to print BCN3D PET CF15 filament? To safely process this filament and avoid immediate extruder wear, it is essential to install the Hotend X with a hardened steel or ruby nozzle with a diameter of 0.6 mm or more. Printing with standard brass nozzles will irreversibly damage the component in a few minutes.
Is it mandatory to use bed adhesives like Magigoo with this material? PET CF15 has an extremely low warping index. It can be printed directly on clean glass surfaces or PEI sheets. The use of adhesives like Magigoo is entirely optional and is only advised for parts with very large bases, always applying it when the bed is cold.
How does the print direction influence the mechanical properties of the part? As detailed in our mechanical specifications table, orientation directly influences them. Printing in the horizontal plane (XY) offers the highest tensile strength (63.2 MPa) and stiffness, while the vertical orientation (ZX) shows lower values (12.5 MPa) due to layer bonding. Plan your model's orientation in the slicing software based on the stresses it will have to withstand.
Why is it easier to use than a Nylon carbon fiber filament (PAHT CF15)? Nylon is a highly hygroscopic material that degrades and causes bubbling or occlusion problems if exposed to air for just a few hours. PET CF15 drastically reduces environmental moisture absorption, offering stable performance over time, simplifying storage, and maintaining repeatability in prints.
Is a special environment or ventilation required for printing? PET CF15 filament emits very low levels of particles and fumes during processing compared to technical plastics like ABS. However, it is advisable to print in adequately ventilated rooms or use professional filtering systems like those integrated in BCN3D's Epsilon series to ensure the best safety conditions.
