BigRep PRO-HT
BigRep PRO HT High-Performance Biopolymer Filament
BigRep PRO HT is a versatile biopolymer filament engineered to deliver excellent printability, consistent part quality, and balanced mechanical performance for a wide range of industrial applications. Designed for functional prototyping, manufacturing aids, and low-volume production, PRO HT is one of BigRep’s most widely used “all-around” engineering materials.
Featuring a clean matte surface finish and reliable processing behavior, PRO HT produces aesthetically consistent parts with minimal post-processing. Its combination of stiffness, impact resistance, and dimensional stability makes it suitable for prototypes, tooling, fixtures, and end-use components intended for indoor and light-duty environments.
Derived from bio-based materials, PRO HT is designed with a reduced environmental footprint compared to fossil-based thermoplastics, while still maintaining dependable industrial performance.
