PETG-GF is a strength enhanced 3D Printing Filament, where GF stands for Glass Fiber. By incorporating glass fibers, PETG-GF becomes naturally waterproof and resistant to temperatures up to 80°C, making it the perfect Filament for parts intended for outdoor conditions. Unlike ASA, PETG-GF does not require a 3D Printer with an enclosed/heated chamber. It is commonly used for outdoor components.
During the 3D Printing process, the addition of glass fibers significantly reduces polymer warping, enabling easier printability. PETG-GF considerably boosts the mechanical properties of printed parts. Its stiffness is twice that of native PETG Filament, and it exhibits 40% higher chemical resistance compared to native PETG Filament.
This fiber is also suitable for electrical applications since glass fibers are non-conductive, unlike carbon fiber PETG.
PETG-GF can also be utilized in plastic extrusion and 3D FGF granular printing.
By controlling the dispersion and distribution of reinforcing fibers in the material matrix through the production process, a net structure is formed by the reinforcing fibers, which bear most of the load transferred from the material matrix. Smart fiber reinforcement technology significantly improves the mechanical properties and heat resistance of the material. Through the net structure of reinforcing fibers, internal stresses generated during printing are relieved, resulting in printed parts with good dimensional stability while without warping issues.
