Description

Dahltram C-250CF Filament is a modified polycarbonate material reinforced with aerospace grade carbon fiber for maximum stiffness and long-term performance. Dahltram C-250CF Filament is ideal for functional prototypes, jigs, fixtures, shop aids, and low volume production parts. In addition to high stiffness and high strength, carbon fiber reinforcement offers excellent thermal properties, and superior dimensional stability.

Benefits

• Carbon fiber reinforced for maximum performance

• Excellent thermal and mechanical properties

• Superior print stability

• Ideal for industrial and engineering grade projects
