PA6 CF15

High temperature construction material

Filament Spectrum PA6 CF15 is made with LUVOCOM 3F PAHT® CF 9742 BK. The quality of the filament was entirely checked and is certified by Lehmann&Voss&Co KG.

Spectrum PA6 CF15 (made with LUVOCOM 3F PAHT® CF 9742 BK) is a black, high-temperature PA6-based construction material modified to achieve better performance. Filling with carbon fibres increases significantly the mechanical strength of the polyamide the material is based on. The filaments specific quality is the moisture absorption reduced by half and the water absorption time is four times lower than that of the pure PA6. Printing does not require a heated chamber and no deformation occurs. The material is compatible with the HIPS and PVOH support materials.

In addition, Spectrum PA6 CF15 (made with LUVOCOM 3F PAHT® CF 9742 BK) features an exceptionally low linear shrinkage (up to 0.1%), a high deformation temperature (240^oC) and low thermal expansion coefficient (0.4 10^-5/K).

Parts made of Spectrum PA6 CF15 (made with LUVOCOM 3F PAHT® CF 9742 BK) allow for long-term operation at elevated temperatures up to 150°C (20.000h) and up to 180°C for a short time operation (max. 200h).

To attain the very attractive properties of Spectrum PA6 CF15 (made with LUVOCOM 3F PAHT® CF 9742 BK), as regards the technical aspects, you need to follow the basic storage rules for such materials (in a dry and dark place with humidity below 15%). To obtain the best parameters of the printed object possible, it is recommended to dry the material prior to work.

Tip: Due to the essential content of chopped carbon fire, it is recommended to use nozzles with diameters exceeding the standard value of 0.4mm. The presence of carbon fibre may also cause wear of standard nozzles; thus it is recommended to use hardened steel or ruby nozzles for prolonged application of Spectrum PA6 CF15 (made with LUVOCOM 3F PAHT® CF 9742 BK).
