• Diameter & Accuracy: 1.75mm (±0.04mm)
• Net Weight: 1kg (2.2 lbs)

Printing Advice & Hardware Recommendations

Due to the abrasive nature of carbon fiber additives, it is strongly recommended to use a 0.6mm (or larger) hardened steel or stainless steel nozzle instead of brass. For best results, dry the filament before printing and utilize an enclosure to maintain a stable ambient temperature during printing.
