Polypropylene based filament filled with 30% glass fibers for Fused Filament Fabrication. Ultrafuse PP GF30 is polypropylene, reinforced with 30% glass fiber content. The fibers in this compound are specially designed for 3D-printing filaments and are compatible with a wide range of standard FFF 3D-printers. The extreme stiffness makes this material highly suitable for demanding applications. Other key properties of PP GF30 are high heat resistance and improved UV-resistance. All these excellent properties make this filament highly suitable in an industrial environment.
