Carbon Fiber ABS Filament has the same great thermal properties as ABS with added strength and rigidity! If your design requirements are demanding you will love our proprietary CF-ABS blend! Filament Properties: Hotend Temperature (°C): 210-240 (Recommended: 230) Bed Temperature (°C): 100-125 (Recommended: 110) Filament Diameter (mm): 1.75±0.05 Net Weight: 1kg (2.2 lbs) Build Surface: Polypropylene or PEI Print Parameters: We have spent thousands of hours testing our filament with several printer types and recommend these printing settings. Default Print Speed: 20-60 mm/s (Recommended: 40 mm/s) First Layer Height: 0.28 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: Layer 1: 0% Layer 3: 0% Layer 4: 0% Layer 5+: 0% XY Jerk: 8 Z Jerk: 0.3 E Jerk: 5 Acceleration (Print/Travel): 300 Retract Acceleration: 1000 Travel Speed (non-print moves): 120 mm/s *Special Notes: Our Carbon Fiber ABS is packed with carbon fiber so we do not recommend printing with a nozzle size less than 0.4mm to prevent clogging (0.6mm or bigger is ideal)
