Victrex has recently launched VICTREX AM 200 filaments that was developed and enhanced for additive manufacturing (AM).

FREMONT, CA: Victrex is a global leader in high-performance polyetheretherketone (PEEK) and polyaryletherketone (PAEK) polymer solutions. The company has recently launched VICTREX AM 200 filaments. The new solution has been mainly developed and enhanced for additive manufacturing (AM). The PEEK incumbent materials that are available in the market can be used in some AM applications, but they were designed for conventional manufacturing methods like machining and injection molding. However, the first 3D printing equipment supplier that offered Victrex's with the new AM PAEK filament is INTAMSYS. This world-leading high-tech organization in China offers high-performance 3D printing materials and direct additive manufacturing solutions and software.

According to Jakob Sigurdsson, the CEO of Victrex CEO, "This new generation of Victrex additive manufacturing PAEK filament represents an important step forward for Victrex and we are excited now to work closely with INTAMSYS. Due to excellent cooperation with companies and institutions that pursue innovation in additive manufacturing, such as INTAMSYS, as well as Victrex's continued research, we have been making sustained progress toward creating truly innovative components based on the design freedom of additive manufacturing, combined with the high performance of PAEK polymers."

The PAEK-based latest VICTREX AM filament has been constructed and improved exclusively for AM. The exceptional mechanical assets of PAEK are in demand for the high-performance parts. However, until it was challenging for them to be fully achieved in 3D printed parts with the present options like PEEK and PEKK. For instance, repurposing the injection molding PEEK into filament fusion AM, generally results in weak parts due to poor interlayer bonding. Furthermore, the new material is intended to focus on this weakness in printing PEEK. As per INTAMSYS' experience utilizing its manufacturing equipment, the VICTREX AM 200 filament has a higher and better Z-axis strength and has shown to date up to 80% strength in the XY direction. It also has an enhanced fused filament-forming (FFF) printing adaptability than the traditional PAEK materials.

According to the Founder and CEO of INTAMSYS, Charles Han, "Our test results to date have shown that the VICTREX AM 200 filament has a better interlayer adhesion than other PAEK materials on INTAMSYS' machines. Compared with unfilled PEEK, it is designed with slower crystallization, lower melt temperature, and a viscosity fine-tuned to the filament fusion process, such as easier flow in the build chamber after leaving the nozzle. Higher flow in the open air (low shear rates) also promotes interlayer bonding and stability during printing." He further said that "all of this contributes to improved interlaminar adhesion, easier printing (less shrink and warp), and better suitability for FDM 3D printing, compared to other similar options, based upon the testing we have done at INTAMSYS up to this point.
