BambuLab PETG-CF Indigo Blue (31600) with Spool, 1kg

BambuLab PETG-CF Indigo Blue is a high-performance carbon fiber reinforced PETG filament designed for demanding 3D printing applications. Combining the ease of printing of PETG with the strength and stiffness of carbon fiber, this filament delivers exceptional dimensional stability and low shrinkage. Ideal for functional prototypes, jigs, fixtures, and end-use parts requiring high strength and rigidity.

Advantages

High strength and stiffness due to carbon fiber reinforcement; excellent dimensional stability and low shrinkage; good layer adhesion; high-speed printing compatibility; recommended for use with hardened steel nozzles for durability.
