Our Pro Series Polycarbonate filament can withstand even the most demanding applications. Its high strength and temperature resistance make it excellent for functional prototypes. We only use quality materials to produce our filament to ensure your printed parts outperform your design requirements. Filament Specs: Hotend Temperature (°C): 235-270 (Recommended: 255) Bed Temperature (°C): 90-120 (Recommended: 100) Filament Diameter (mm): 1.75±0.05 Net Weight: 1kg (2.2 lbs) Build Surface: PEI Print Parameters: We have spent thousands of hours testing our filament with several printer types and recommend these printing settings. Default Print Speed: 30-60 mm/s (Recommended: 40 mm/s) First Layer Height: 0.24 mm First Layer Speed: 15 mm/s Extrusion Width: 0.48 for 0.4 Nozzle (1.2X Nozzle Diameter) Retraction: Bowden 5mm @ 45 mm/s or Direct 2mm @ 45 mm/s Perimeter Print Speed: 70% of Default Print Speed Infill and Support Print Speed: 80% of Default Print Speed Fan Profile: 0% (Fan Not Recommended) XY Jerk: 8 Z Jerk: 0.3 E Jerk: 5 Acceleration (Print/Travel): 300/500 Retract Acceleration: 1000 Travel Speed (non-print moves): 120 mm/s *Special Notes: PC absorbs water from the air quickly. We recommend drying filament before first use and storing airtight with desiccant to maintain dryness. Please see our article on how to dry filament. Symptoms of wet filament include hotend popping and finished parts that are brittle due to poor layer adhesion. Our PC will print at a wide range of temperatures but layer adhesion is much better at the top end of the suggested range.
