A short overview of powder-mixed electrical discharge machining in biomedical materials

Background The demand for biocompatible materials has increased substantially in recent years as a result of the growing complexity and precision requirements of medical devices, particularly implants. However, the process of manufacturing these materials remains challenging, particularly in terms of preserving biocompatibility while attaining a high level of surface quality. Objective The objective of this study is to present a concise summary of Powder-Mixed Electrical Discharge Machining (PMEDM) and Electrical Discharge Machining (EDM) for biomedical materials, with an emphasis on their potential to circumvent the constraints of traditional methods. Methods In order to ascertain the capabilities, limitations, and contributions of EDM and PMEDM to biomedical applications, a review of recent studies and discussions was conducted. Results The results emphasize that EDM and PMEDM can efficiently process challenging biomedical materials without causing mechanical stress, while simultaneously enhancing surface characteristics and maintaining biocompatibility. These techniques demonstrate potential for improving the precision and quality of biomedical components. Conclusions EDM and PMEDM are prospective manufacturing techniques for biomedical applications, assuring the reliable biological integration of implants in clinical practice, long-term performance, and structural accuracy.
