COMPOSITE MATERIAL DATASHEETVegaTMCARBON FIBER FILLED PEKK MATERIAL
Vega is an ultra high-performance carbon fiber filled PEKK for3D printing critical aerospace parts on the FX20. Formulatedby Markforged engineers and material scientists, it exhibits
a smooth matte black surface finish that is excellent for
production parts. Vega can be reinforced with continuous fiber
to achieve aluminum strength for aerospace components.
High Temperature Carbon Fiber (CF-HT) is a specialized variantof Markforged’s continuous Carbon Fiber designed for use
with Vega and ULTEM™ 9085 Filament*. Capable of yieldingaluminum strength parts, it can be precisely laid down in a wide
variety of geometries.
Features and benefits
High heat and FST resistanceChemical and solvent resistanceLow outgassing
Matte surface finish

Directional Mechanical Properties of Vega
The mechanical properties of 3D printed materials may vary with print orientation. In tension, most parts are strongest when theprint orientation and loading direction are parallel, and weakest when the print orientation and loading direction are perpendicular.
