Large 2.5kg Capacity for Maximum Efficiency – Designed for print farms, industrial users, and large-scale projects, this high-capacity spool minimizes filament changes, improving workflow and reducing downtime for continuous printing. Carbon Fiber Reinforced for Superior Strength – PET-CF combines high-strength PET with carbon fiber, delivering enhanced rigidity, wear resistance, and durability for functional and load-bearing parts. High Precision & Dimensional Stability – Engineered for precision printing, this filament maintains consistent diameter, smooth extrusion, and minimal warping, ensuring accurate part dimensions and a flawless surface finish. Optimized for Industrial & Functional Applications – Perfect for engineering-grade parts, including industrial components, fixtures, molds, UAV parts, and automotive applications requiring high strength and long-term reliability. Seamless Upgrade & Optimized Storage - Easily transition from 1kg to 2.5kg with no changes to your print settings—enjoy longer, uninterrupted printing with the same trusted performance. Each spool is vacuum-sealed in an aluminum foil bag for maximum moisture protection. To maintain optimal print quality, always store PET-CF filament in the provided bag or a dedicated dry box when not in use, as PET-CF is highly sensitive to humidity. Siraya Tech Fibreheart PET-CF (2.5kg) – Engineered for High-Performance 3D Printing.
Siraya Tech’s Fibreheart PET-CF now comes in a 2.5kg large-capacity spool, designed for industrial users, print farms, and large-scale manufacturing. Built upon the success of our 1kg PET-CF, this carbon fiber-reinforced PET filament delivers exceptional strength, durability, and dimensional accuracy, while allowing for longer, uninterrupted prints without frequent spool changes.
