Abstract

Scaffold or porous architectured structure is essential in biomedical application for cell growth or for mass reduction if to be used in automotive and aerospace applications. The structure was once impossible to fabricate but now viable using additive manufacturing techniques. However, in order to reduce weight structure and save on materials using porous structure, strength is one key feature must be maintained to serve the function. The aims of the study are to compare the part strength with different cell repetition and porosity (ranging 56% to 70.45%), and also to determine pattern of stress concentration in different unit cell size. In this study, cubic scaffold-based structures with critical porosity range were simulated using ABAQUS. From the simulation it can be observed generally that strength will reduce with higher porosity, while 58.96% of porosity showed less stress concentration. For each porosity, stress concentration and deflection can be observed and compared. The result of the study is important to help designer to choose suitable design and porosity prior to fabrication.
