High-Temperature Construction Material

The Spectrum PA6 CF15 filament is a black high-temperature construction material based on polyamide 6. The 15% carbon fiber filling significantly increases the mechanical strength of the polyamide that forms the basis of the material. A characteristic feature of this material is that moisture absorption is halved compared to pure PA6, and the water absorption time is four times lower than that of pure PA6. No heated chamber is required during printing, and there is no deformation (shrinkage). The material is compatible with support materials HIPS and PVOH.

Furthermore, the Spectrum PA6 CF15 filament is characterized by very low linear shrinkage (no more than 0.1%) and a very high heat distortion temperature (HDT 240 °C), as well as a low coefficient of thermal expansion (0.4 x 10^-5/K). Components made from Spectrum PA6 CF15 can be used at elevated temperatures of up to 150 °C for long-term (20,000 hours) and up to 180 °C for short-term (max. 200 hours) applications.

The technically attractive properties of Spectrum PA6 CF15 filament can be achieved by adhering to the basic storage rules for this type of material (in a dry and dark place with humidity below 15%). To achieve the best possible parameters for the printed object, it is recommended to dry the material before starting work.

Note: Due to the high carbon fiber content, it is recommended to use nozzles with a larger diameter than the standard diameter of 0.4 mm. Additionally, the presence of carbon fibers may lead to wear of standard brass nozzles. Therefore, hardened steel or ruby nozzles are recommended for long-term use of Spectrum PA6 CF15.
