  • Prototyping

    We provide a prototyping and low-volume production service based on high-performance FDM (Fused Deposition Modeling) 3D printing, utilizing composite materials reinforced with carbon fiber or glass fiber. These engineered thermoplastics offer mechanical properties up to 10 times higher than standard polymers, ensuring superior structural integrity under load. This solution is particularly suitable for functional components such as gears, housings, and brackets, with the option of localized fiber reinforcement to enhance load-bearing capacity, stiffness, and long-term durability.
