Green Manufacturing-Oriented Polyetheretherketone Additive Manufacturing and Dry Milling Post-Processing Process Research

The application of polyetheretherketone (PEEK) in additive manufacturing (AM) can effectively reduce material and energy waste the process help achieve lightweight parts. As a result, AM PEEK is considered an emerging technology line with green concepts. However, 3D-printed parts often suffer from low mechanical strength poor surface quality due to immaturity process. Therefore, this research investigates feasibility improving by dry milling post-processing. Meanwhile, improved optimizing printing parameters, effects on are investigated. novelty design experiments based anisotropy For first time, delamination post-processing results show that milled surfaces prone problems. direction has significant effect post-processing, whereas directions have little quality. problem be significantly side where specimen printed at 90° then milled. Milling caused (internal bonding) By parts, its improved.
