Frequently Asked Questions
What is PP GF30 filament and what are its main uses? PP GF30 filament is a material composed of polypropylene reinforced with 30% short glass fiber. It is especially suitable for manufacturing industrial mechanical components with high rigidity, low weight, and excellent chemical resistance to oils, fuels, and solvents in the automotive and heavy machinery sectors.
What type of nozzle is needed to print BCN3D PP GF30? Because it contains 30% highly abrasive glass fibers, it is mandatory to use a nozzle diameter equal to or greater than 0.6 mm made of hardened steel or tungsten carbide. Standard 0.4 mm brass nozzles experience immediate wear and risk continuous clogging with fibers.
How should the print bed be configured to prevent warping? The thermal configuration depends on the adhesion material. If you use polypropylene (PP) adhesive tape, the bed temperature should be set low, between 20 and 40 °C. If you use a special liquid adhesive for PPGF on glass, the print bed should be heated in a range of 70 to 90 °C to ensure optimal adhesion of the base layers.
Does this filament require mandatory drying before use? Yes, to ensure that the structural properties of the printed parts remain uniform and stable, it is advisable to perform preventive drying of between 4 and 16 hours at 60 °C in a vacuum oven or hot air dehumidifier before starting long-duration prints.
How does printing direction affect the material's tensile strength? The material exhibits controlled anisotropic nature. When printed flat (XY direction), it offers its maximum tensile strength of 41.7 MPa. However, in a fully vertical orientation (ZX direction), the adhesive forces between layers limit the tensile strength to 15.9 MPa. It is recommended to orient the parts so that the extrusion lines follow the vector of the main design forces.
