Abstract Scope |
Polyether-ether-ketone (PEEK) is a high-performance thermoplastic material with high heat resistance, high chemical resistance, high water resistance, and high wear resistance. Due to its distinguished strength and durability, PEEK is extensively used for aerospace, automotive, and medical applications. 3D printing PEEK filaments offer a new approach to make PEEK parts, fulfilling specific requirements of geometrical complexity. But the mechanical properties of 3D printed PEEK materials are not further explored. This study investigated the mechanical properties of PEEK materials fabricated using the fused deposition modeling (FDM) 3D printing process. Tensile test, hardness test, and impact test were conducted to the PEEK samples, in compliance with ASTM standards. The testing results were summarized and discussed, compared to the conventionally manufactured PEEK materials. This study also provides insights on employing FDM 3D printing process for making PEEK parts, based on its special mechanical properties and failure mode. |
