PP (Polypropylene) 3D printer filament is a lightweight, low-density material that offers exceptional chemical resistance, high impact strength, and excellent flexibility. It is tough, semi-rigid, and resistant to fatigue, making it ideal for functional parts like living hinges, snap-fit components, chemical containers, and automotive applications. PP also provides good heat resistance and electrical insulation properties. However, it can be challenging to print due to warping and poor bed adhesion, often requiring a specialized build surface or adhesive. When dialed in correctly, PP filament produces durable, lightweight parts that can withstand repeated bending and exposure to harsh chemicals.
