Birch is a product series of JIANYU, which provides a "High-strength" solution for 3D printing filaments. It has excellent mechanical properties and print quality, and exhibits great tensile strength and durability, making it suitable for long-term stress scenarios. COCOON PA-Birch(GF) is a 3D printing specialty filament primarily made from renewable natural plants, featuring high strength, high fluidity, low moisture absorption, low shrinkage, and low warping. Compared to traditional petroleum-based polyamides, its raw materials are renewable and offer better sustainability. Components printed with this material have excellent dimensional stability. This filament is suitable for printing structural parts with specific strength or environmental requirements, such as wind turbine blades, low-voltage electrical structural components, electric tools, gears, etc.
