The Hyper Core PPA CF25 filament by Raise3D represents a breakthrough in filament technology, specifically tailored for industrial and professional applications requiring exceptional strength, stiffness, and heat resistance. Traditional fiber-reinforced composite filaments offer unparalleled performance for heavy-duty tasks, yet they pose challenges during high-speed printing, including reduced flowability, inferior interlayer bonding, and accelerated nozzle wear. The Hyper Core filament line addresses these issues head-on, ushering in a new era of efficiency and quality in Hyper FFF printing.

At the heart of the Hyper Core PPA CF25 filament lies a revolutionary technology engineered to create a fiber-rich inner core, where 25 wt.% of carbon fiber is meticulously aligned and distributed. Thanks to the exceptional heat conductivity of the carbon-fiber rich core, this design optimizes filament melting in the hot end. Moreover, the abundance of residual thermal energy derived from the inner core enhances polymer healing and welding processes, significantly improving interlayer bonding and overall print quality. Compared to standard PPA CF filaments, the Hyper Core PPA CF25 boasts remarkable enhancements in Z-direction strength, surface finish, and nozzle longevity.

The Hyper Core PPA CF25 filament stands out for its unmatched strength, stiffness, and mechanical stability, even at elevated temperatures. It exhibits outstanding resistance to deformation under external forces and breakage under impact, while ensuring excellent interlayer bonding for robust, reliable prints. For optimized part properties, annealing at 80-100 ºC for 8 hours is recommended.

Applications

Designed to unleash its full potential, the Hyper Core PPA CF25 filament is tailored for use with 3D printers from the Raise3D Pro3 series equipped with the Hyper Speed Upgrade Kit, as well as the RMF500 industrial 3D printer. Leveraging the capabilities of ideaMaker Version 5.0.5 is essential for achieving optimal results with this material. The versatility of the Hyper Core PPA CF25 filament opens up a myriad of applications across industries, including automotive, aerospace, manufacturing aids, jigs & fixtures, functional parts, and the electrical and electronics (E&E) sector.

Storage

Nylon is a very hygroscopic material. Despite being developed to reduce its moisture absorption, it is recommended to store the Hyper Core PPA CF25 in vacuum sealed packaging. By placing the Slice Engineering filament drying capsule inside the spool, even better results can be achieved. In case the filament absorbs too much moisture, it is recommended to dry it for 6 to 12 hours at a temperature of 80-100 °C in a professional filament dryer and store it in the Raise3D Dry Box during printing.

Printing

Carbon fibre reinforced filaments are very abrasive. This means that the nozzle is at a much higher risk of wear than with non-reinforced filaments. The user must ensure to use a hardened steel Raise3D nozzle. The recommended printing settings for this material are as follows: extrusion temperature of 300-330 ºC, bed temperature of 70-80 ºC, printing speed of 25-300 mm/s, a layer height of 0.1-0.25 mm, and the cooling fan on.

Supports

If Hyper Core PPA CF25 is used as its own support material, the support structure should be removed before annealing. Otherwise, it may become permanently attached to the model due to moisture absorption. Another recommended support material is the PPA Support and if this one is used, it can be removed after annealing.

Annealing

After printing, it is recommended to anneal the model in an oven at 80-100 °C for 8 hours to improve mechanical properties and dimensional accuracy. Then let the parts cool down to room temperature naturally. Following annealing, a maximum shrinkage of 0.5 % may occur along the Z-axis, depending on infill and layer height, while there should be no noticeable shrinkage in the XY-axis.
