THE K7™ PET CF10

Nozzle Temperature: 250–290°C

Bed Temperature: 90–110°C

Bed Modification: PEI frosted board

Active Cooling Fan: 0–50%

Layer Height: 0.2 mm

Shell Thickness: ≥ 0.8 mm

Print Speed: ≤ 300 mm/s

Note: Settings are based on a 0.4mm nozzle. A hardened steel or ruby nozzle is recommended due to carbon fiber abrasiveness.

Carbon Fiber Reinforcement: Chopped carbon fibers are embedded into the polymer matrix, dramatically enhancing tensile performance, dimensional accuracy, and structural integrity.

High Mechanical Strength & Stiffness: Delivers exceptional modulus and load-bearing performance, making printed parts ideal for demanding functional prototypes and end-use structural components.

High Surface Hardness & Wear Resistance: Features a rugged surface finish that resists scuffs, scratches, and mechanical wear under repeated friction.

Low Moisture Absorption (Superior to PA-CF): Significantly less hygroscopic than traditional polyamide (nylon) composite materials, eliminating the need for constant pre-print drying cycles and preventing steam bubbling during extrusion.

No Buckling Deformation & Anti-Warping: Carbon fiber alignment neutralizes internal thermal stress during cooling, preventing bed detachment, edge curling, or part deformation.

Good Interlayer Bonding: Specially modified resin base optimizes Z-axis cohesion to ensure high structural reliability along all stress axes.

Easy Printability for Entry-Level High Performance: Bridges the gap between basic desktop materials and advanced engineering plastics, providing accessible, hassle-free processing on standard desktop printers.

Environmentally Friendly Formulation: Uses sustainable base polymers combined with non-hazardous additives for low-odor, safer printing environments.
