We took our PETG filament to the next level by adding 20% chopped Carbon Fiber. If your design requirements are demanding you will love our proprietary Carbon Fiber PETG blend! Filament Properties: Hotend Temperature (°C): 220-250 (Recommended: 225) Bed Temperature (°C): 75-85 (Recommended: 80) 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 starting with the following settings: Default Print Speed: 30-60 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: 25% Layer 5+: 50% 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 Additional Notes: Our Carbon Fiber PETG 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) Most users who are used to printing PLA tend to set their first layer height too low. PETG tends to build-up on the nozzle during the first layer causing adhesion issues. We recommend a first-layer thickness of 0.28mm.
