Carbon fiber filament is a new blended filament that yields high quality prints. The PLA base material is blended with approximately 20% of high modulus carbon fiber. The chopped up carbon fiber adds dimensional stability and increased stiffness. The light weight carbon fiber is easy to print and results in excellent surface quality.As with all Gizmo Dorks products, carbon fiber filled filament is only produced using the highest grade raw materials. Precision leading equipment measures and controls diameter tolerances. The filament will be free of voids and cavities that cause uneven printing and lead to failures. Each hard durable plastic spool comes vacuum sealed and packed with a desiccant to prevent moisture absorption. When not in use, please store filament properly in a sealed container.Please note - carbon fiber filled filaments are abrasive and may lead to premature wear in brass or aluminum nozzles. We recommend using hardened steel nozzles as they are much more wear resistant.Printer Settings Extruder temperature: 180 - 220 ℃. Bed temperature: 100 - 120℃.
