PP (polypropylene), due to its fatigue resistance, semi-elasticity and light weight characteristics, makes it very suitable for high cycle, low strength applications. PP is a semi-rigid and lightweight material. Its semi-crystalline structure causes 3D printed parts to warp easily when cooling. PP is tough and has good fatigue resistance. It is suitable for low-strength applications such as movable hinges and belts. .

Features:

． Good impact and fatigue resistance, heat resistance

． The surface is smooth and smooth but prone to warping

． Less powerful, more expensive
