Sunlu PA12-CF 1.75 mm 1 kg

The filament SUNLU PA12-CF It's an advanced 3D printing solution for those who require maximum strength, lightness, and high-temperature resistance. This material combines polyamide 12 (PA12 nylon) with carbon fiber reinforcement, resulting in components that maintain their shape even under thermal stress, repeated impacts, and harsh environments.

Thanks to the presence of carbon, PA12-CF exhibits exceptional mechanical strength , extraordinary rigidity, low density, and very high dimensional stability, even with very low moisture absorption. Perfect for field applications. automotive, aerospace, sports and industrial , it is ideal for the production of technical parts, gears, tools, housings, drones and structural components designed to last over time.

The surface of the printed parts is smooth and abrasion-resistant, with remarkable resistance to wear and impact. Filament maintenance is simple, but the use of hardened steel nozzles is recommended to prevent carbon-related wear.

Usage and post-processing tips

• Store in a dry environment and, if necessary, dry the filament before printing (80°C for 12h or 110°C for 4h) .
• Use adhesive on the print bed to prevent warping.
• Post-printing annealing is recommended to further improve mechanical resistance (80–130°C for 3–12h) .
• Nozzle wear can be significant: hardened steel nozzles are preferred.
