| Abstract Scope |
Polyetheretherketone (PEEK) is an engineering grade thermoplastic with high performance and high reliability. PEEK has excellent mechanical properties and chemical compatibility. Another desirable property of PEEK includes the ability to operate in much higher temperature environments compared to other commonly used additive manufacturing polymers. However, PEEK can be very difficult manufacture through Fused Deposition Modeling (FDM) due to the properties mentioned above and requires high nozzle temperature and a heated build chamber. Some printing defects of FDM PEEK include inaccurate dimension, poor layer adhesion, varying surface topography, and excessive warping. To minimize the defects during the printing process, we optimized print parameters which include print speed, extrusion/retraction rates, and print process temperature. This resulted in improved part characteristics while benefitting from FDM style additive manufacturing to create complex structures. |
