PETG-CF 3D PRINTERS PLASTIC FILAMENTS 1.75mm x 1KG — Red

PETG-CF Filaments - 1KG Spool - 1.75mm The PETG-CF (Carbon Fiber Reinforced PETG) 3D Printer Filament (1.75mm x 1kg) is a high-yield, structural engineering-grade composite material featured in the Dabbous Mega Supplies 3D Filament Collection . By infusing premium glycol-modified polyethylene terephthalate (PETG) with chopped carbon fiber micro-strands , this advanced consumable delivers structural rigidity, dimensional stability, and impact strength. It is the premier choice for drone manufacturers, automotive engineering firms, aerospace prototyping labs, and industrial automation facilities across Lebanon looking to print lightweight, functional parts that cannot bend under load. 📋 Technical Specifications & Composite Advancements Commercial Package Dimensions: Standardized 1.75mm diameter wire precision-wound on a heavy-duty 1kg net weight spool , manufactured with strict dimensional tolerances (±0.03mm) to guarantee jam-free extrusion. Exceptional Structural Rigidity (High Modulus): Standard PETG is highly ductile and flexible; the addition of carbon fiber strands significantly increases its tensile strength and stiffness. This prevents printed components from warping, flexing, or bending under heavy mechanical loads. Ultra-Low Shrinkage & Dimensional Accuracy: The internal carbon fiber reinforcement drastically reduces the material’s thermal expansion coefficient. This minimizes warping and shrinking, allowing large-scale, intricate models to be printed with tight geometric tolerances. Premium Matte Industrial Finish: Yields a high-end, matte black textured surface finish that naturally hides visible print layer lines. This eliminates the need for tedious manual post-processing and gives parts a professional, injection-molded commercial appearance. Inherent PETG Advantages: Retains PETG’s baseline chemical resilience, water resistance, low moisture absorption, and ease of printing compared to nylon-based carbon fiber composites. ⚙️ Professional 3D Printing Calibration Parameters Because carbon fiber micro-strands are highly abrasive and affect heat transfer, engineering labs should use these baseline machine configurations: Extruder/Nozzle Type: Hardened Steel or Ruby Nozzle is mandatory. Standard brass nozzles will wear out and widen within a few hours of printing carbon fiber composites. Nozzle Diameter: 0.4mm minimum (0.6mm recommended). Chopped carbon fibers can accumulate and cause structural clogs in smaller 0.2mm nozzles. Extruder/Nozzle Temperature: 240°C – 260°C (Optimizes interlayer bond fusion) Heated Bed Temperature: 70°C – 80°C (Paired with glue stick or PEI sheet for reliable bed anchoring) Print Velocity / Speed: 30mm/s – 60mm/s (Slower speeds ensure optimal carbon strand alignment and layer adhesion)
