The Hyper Core filament series represents a new generation of professional and industrial fiber-reinforced composite filaments for Hyper FFF®. Fiber-reinforced composite filaments are a well-known material for manufacturing end-use parts and high-performance applications, offering superior strength, stiffness, and heat resistance. However, high-speed printing with fiber-reinforced filament presents many challenges, such as reduced flowability, poorer interlayer adhesion quality, and faster nozzle wear. To address these challenges, Raise3D has developed a new extrusion technology to create a filament cross-section with a fiber-rich inner core and a polymer-coated outer layer for the Hyper Core family. During high-speed FFF printing, the thick polymer skin of the Hyper Core PPA GF25 filament enhances polymer curing and the welding process at the interface between adjacent layers and lines. The Hyper Core PPA GF25 is optimized for a fast melting rate at the hot end, as well as for a good balance between printing efficiency, quality, performance, and cost. Thanks to its special distribution structure of coated skin and fibers (25 wt.%), Hyper Core PPA GF25 exhibits high stiffness (6.6 GPa), strength (98 MPa), heat resistance (189 ℃), and excellent print quality. Hyper Core PPA GF25 is an ideal choice for various industrial applications where high performance, stability, and cost efficiency are required.
