The PA-CF is Carbon Fibre filled nylon. As such it is highly abrasive, and will destroy the standard TAZ 6 aerostruder nozzle and hobbed bolt. We include profiles for the PA-CF in the HS and HS+ tool head options, as these have hardened steel hobbed bolts and nozzles to prevent wear on the components.
