An Overview of Polypropylene Filament
Polypropylene is a semi-rigid and lightweight material that is commonly used in storage and packaging applications. The semi-crystalline structure of the material causes the 3D printed parts to heavily warp upon cooling, making it challenging to 3D print.
Polypropylene is tough and has a good fatigue resistance making it ideal for low strength applications like living hinges, straps, leashes, etc. A few manufacturers have even created polypropylene blends that have improved toughness making it suitable for practical use.
