PP
( number of products: 1 )Spectrum PP is a lightweight, chemically resistant filament made from unfilled random copolymer polypropylene. It offers outstanding flexibility (elongation up to 500%), low moisture absorption, and high impact resistance. With excellent interlayer adhesion and minimal shrinkage (0.3%), it’s ideal for producing strong, durable parts for engineering and industrial use – no heated chamber required.
Spectrum PP is a professional-grade 3D printing filament based on unfilled random copolymer polypropylene. This material combines low density with excellent mechanical strength, impact resistance, and high flexibility — up to 500% elongation at break. Its exceptional chemical resistance makes it suitable for demanding environments, while its reduced moisture absorption (≤0.3%) and low shrinkage (~0.3%) ensure stable and accurate prints.
Spectrum PP does not require a heated chamber, and thanks to its enhanced layer bonding, the printed parts are less anisotropic and more dimensionally stable. Its very good tribological properties (including suitability for dry friction conditions such as slide bearings) and resistance to thermal aging make it ideal for mechanical and functional components.
To achieve the best results, it’s recommended to dry the material before use and store it in a dry, dark place with humidity below 15%. For better bed adhesion, Magigoo PP or a dedicated polypropylene build plate is advised. This filament is the perfect choice for high-performance parts in automotive, industrial, and technical applications.
