Spectrum PET CF15 is a material based on polyethylene terephthalate in black, mass-dyed. It is the easiest carbon fiber material on the market for 3D printing. The filament has no retraction problems and there is no need for a heating chamber during printing. A characteristic feature of the filament is the perfect surface finish straight after removing the model from the printer, thus reducing the need for post-processing.


Spectrum PET CF15 is compatible with auxiliary materials such as HIPS-X. The filament allows you to print very strong and stiff elements. It is characterized by a low influence of moisture and temperature on dimensions. The models produced can be subjected to additional heat treatment to improve their mechanical properties.


Key Features:


low processing shrinkage (linear) 0.1%

high temperature of short-term operation reaching 125 ° C (up to 200h)

relatively high resistance to thermal aging

high strength in the Z axis

high hardness, stiffness and creep resistance of printed elements

chemical resistance to greases and oils

good tribological properties, also under the dry friction conditions found in plain bearings

very strong lamination of layers

very good toughness

low water absorption 0.3% (23 ° C / 24h)

Due to the high content of carbon fiber, it is recommended to use nozzles with diameters exceeding the standard value of 0.4 mm.

The presence of carbon fiber can also wear out the brass nozzle, so it is recommended to use stainless steel nozzles for long-term use of PET CF15.
