Improve your print quality with our Pro Series PETG+ filament. We only use quality materials to produce our filament to ensure your printed parts outperform your design requirements. Filament Specs: Hotend Temperature (°C): 220-245 (Recommended: 230) 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 these printing 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 *Special Notes: 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.
