Finite Element Modelling and Simulation of Bio-Interfaces on Micro-EDM Machined Surfaces

Abstract Micro-Electrical Discharge Machining (EDM) process textures have garnered significant interest due to their unique characteristics and potential applications in various fields. This research aims to define the base for investigating the crucial aspect of evaluating the antibacterial properties and/or biocompatibility of surfaces textured by the typical crater-like features generated through micro-EDM. The focus of this study is the development of a numerical simulation framework based on scanned surfaces to comprehensively assess if the traditional crater texture is sufficient to attribute these characteristics to the surfaces. The importance of this research lies in addressing the growing demand for advanced surface engineering techniques that not only improve functionality but also ensure safety in medical, industrial, and consumer applications. Using numerical simulations, this study aims to provide insights into the interaction between surface topography and antibacterial properties, providing a convenient and efficient tool for evaluating surface characteristics. The findings of this study are anticipated to contribute significantly to the advancement of surface engineering technologies, offering novel solutions for combating bacterial colonization and improving biocompatibility. Furthermore, the development of a numerical simulation framework holds promise for accelerating the design and evaluation of textured surfaces, thereby streamlining the innovation process in various industries.
