Abstract

This paper presents the efforts made in the design, fabrication and experimentation to find compressive nature of porous triply periodic minimal surface structures made of polylactic acid material in order to determine the compressive stress vs strain porous structures fabricated with the fused deposit modeling process for biomedical applications. The problem concerned here is the determination of stress-strain graph of  structure with INSTRON machine. The work is focused on designing the triply periodic minimal surface polylactic acid structure and studying the compressive forces of structures. The three-dimensional triply periodic minimal surface-based lattice structures with porosity ranging from 10 to 50% porosity were designed, fabricated and experimented. This work establishes the appropriate porosity which can handle optimum compressive forces between the implant and the bone by adding the porosity to the implant structure.
