Abstract

The paper describes the importance of optimization of lattice structures intended to be used in medical applications. Additive manufacturing process gains an important place in the medical industry due to the ability to obtain complex geometries, lattice structures impossible to be achieved using conventional technologies. Developed as a new type of lightweight material, and inspired by natural cellular materials, lattice structures thanks to the possibility of obtaining characteristics as close as possible to bone characteristics, are successfully used in the medical field. In this paper, three types of lattice structures with two different porosity were designed and fabricated using selective laser melting and were investigated for optimization. Thus, the aim of this paper is to provide information on the optimization of lattice structures intended to be integrated into medical devices, in order to improve their use in the medical field.
