Fiberon PA612-CF15 Carbon Fiber Filament 1.75mm 1kg - Black

Fiberon PA612-CF15 by Polymaker is a carbon fiber-reinforced filament based on a long-chain copolyamide (PA612). Thanks to its chemical structure, this material absorbs significantly less moisture than filaments based on PA6/66 or PA6 and offers better mechanical properties than PA12-based materials. The carbon fiber reinforcement combined with Polymaker's Warpfree™ technology ensures high dimensional stability of printed components. This filament is particularly suitable for demanding technical applications where stiffness, strength, and heat resistance are required. With a heat deflection temperature (HDT) of 114 °C at 1.8 MPa and 175 °C at 0.45 MPa, the material is also suitable for thermally stressed components. The density is 1.03 g/cm³, and the material meets the flame retardancy classification UL 94 HB at a wall thickness of 1.5 mm. A fully metal hot end with a temperature resistance of at least 250 °C is recommended for printing. Since carbon fibers are abrasive, the use of a hardened nozzle is strongly recommended, as a brass nozzle will wear out after approximately nine hours of print time. After printing, annealing at 100 °C for 16 hours and subsequent moisture conditioning is recommended to achieve optimal mechanical properties. The filament should always be stored and processed under dry conditions with a relative humidity below 20%. PolyDissolve™ S1 and PolySupport™ for PA12 are compatible as support materials.

Recommended Accessories:

• 1 Liter Isopropyl Alcohol / Isopropanol 99.8%
• 3DLac Adhesion Spray 400ml
• Brass Wire Brush for Hot End / Nozzle Cleaning
• 3D Printer Accessories Kit
• 0.4mm MK8 Micro Swiss M2 Hardened Steel Coated Nozzle

Features:

• Carbon fiber reinforcement increases stiffness and dimensional stability of printed parts.
• Warpfree™ technology reduces warping when printing large parts.
• Low moisture absorption compared to PA6- and PA6/66-based filaments.
• High heat resistance with an HDT of 114 °C at 1.8 MPa.
• Compatible with PolyDissolve™ S1 and PolySupport™ for PA12 as support material.
• Hardened nozzle required as carbon fibers heavily wear brass nozzles.
