Siddament PC-CF Carbon Fibre Filament — 1.75mm 1kg
Siddament PC-CF Carbon Fibre Filament — 1.75mm 1kg
Siddament PC-CF on a 1.75mm, 1kg spool. Polycarbonate reinforced with 10% chopped carbon fibre by weight, milled to around 0.04mm.
This is the top of the range for heat and stiffness. With a 117°C heat deflection temperature and 38 kJ/m² notched impact strength, it handles the jobs PETG and ASA can't — under-bonnet automotive parts, jigs that see heat, structural brackets and functional prototypes that need to hold tolerance while hot.

Sidd's notes
Carbon fibre is abrasive. Run a hardened steel nozzle or you will chew out a brass one.
Polycarbonate picks up moisture fast — dry it before a long print or you'll get stringing and weak layers.
