Spectrum ecoPET 9021 Black Filament – 1.75mm, 0.75kg

Spectrum ecoPET 9021 Black is a high-performance technical PET filament designed for users who need greater rigidity, strength, and thermal resistance than conventional PETG. Manufactured with more than 90% recycled content, this advanced material combines sustainability with engineering-grade performance, making it an excellent choice for functional parts, prototypes, tooling, and production applications.

Unlike standard PETG, ecoPET 9021 is based on non-glycol-modified PET, resulting in significantly higher stiffness and tensile strength while maintaining excellent printability and layer adhesion. The material offers impressive thermal resistance up to 125°C under long-term exposure conditions, making it suitable for demanding environments where conventional PETG may fall short.
