Filament Spectrum PA6 CF15

High-temperature structural material

Filament Spectrum PA6 CF15 is a black high-temperature structural material based on polyamide 6. 15% carbon fiber filling leads to a repeated increase in the mechanical strength of the polyamide that forms the base of the material. A characteristic feature of this material is the halved moisture absorption compared to pure PA6, and the water absorption time is four times less compared to pure PA6. During printing, a thermal chamber is not necessary, and no deformations (shrinkage) occur. The material is compatible with support materials HIPS and PVOH.

In addition, the filament Spectrum PA6 CF15 is characterized by very low linear shrinkage (does not exceed 0.1%) and very high deformation temperature (HDT 240°C) and low coefficient of thermal expansion (0.4 10^-5/K).

Elements made using Spectrum PA6 CF15 allow work at elevated temperatures reaching 150°C long-term (20,000 h) and up to 180°C short-term (max. 200h).

Very attractive technical properties of the filament Spectrum PA6 CF15 are achievable while maintaining the basic principles of storing this type of materials (in a dry and dark place with humidity below 15%). To achieve the best parameters of the printed object, it is recommended to dry the material before starting work.

Tip: Due to the significant content of carbon fibers, it is recommended to use nozzles with a diameter larger than the standard 0.4 mm. In addition, the presence of carbon fibers can lead to the degradation of standard brass nozzles, so for longer use of Spectrum PA6 CF15, it is recommended to use nozzles made of hardened steel or ruby.

Key properties:

• unusually low shrinkage during processing (linear) 0.1%
• high thermal resistance up to 180°C for short-term work (max. 200h)
• high thermal resistance up to 150°C for long-term work (20,000 h)
• heat deflection temperature – HDT A 240°C (ISO 75)
• water absorption below 0.3% (23°C/24h)
• high abrasion resistance
• high mechanical resistance
• very strong layer lamination
• high creep resistance
• high hardness and stiffness of the produced elements

Applications:
