Subsequently, modelling and FE simulations were carried out to predict their mechanical response. Compression tests were carried out to characterize their mechanical behavior. In this work, samples with different lattice structures were manufactured by Laser Powder Bed Fusion technique using Co-Cr-Mo alloy. Moreover, many common CAD software have a lack of materials libraries and geometry flexibility. This problem is mostly caused by the computational effort and number of design parameters that the implementation of these materials in a Finite Element Modelling (FEM) analysis requires. However, their use is still limited, mainly due to the lack of methods to fully implement them during the production and to virtually predict all their mechanical properties. In addition, their structure is really close to some physiological tissues, which can allow their use to develop prostheses needed to the rehabilitation or replacement of a body part. The lattice structures are a particular type of structures made by the repetition of a unit cell and show great design opportunities. This article presents an extensive analysis on the use of finite element modeling for the design, testing and development of prosthesis and orthosis devices. Moreover, the simulations are useful to eventually improve the design (as geometry, materials, features) before the actual production of the device. Moreover, through finite element analysis software and the knowledge of loads and conditions the prostheses are supposed to face in vivo, it is possible to simulate, analyze and predict the mechanical behavior of the prosthesis and its effects on the surrounding tissues. Computer-aided design tools can be used to develop a device that respects the design requirements as, for instance, the human anatomy. Data acquisition through magnetic resonance imaging, computed tomography or laser scanning is the first step that gives information about the human anatomical structures a file format has to be elaborated through computer-aided design software. Computational simulations are used to evaluate the geometrical and material designs of a device while assessing its mechanical behavior. Modeling and simulation of prosthetic devices are the new tools investigated for the production of total customized prostheses.
