Insight of the elastic behavior of isotropic and anisotropic materials in large deformations. Learning the foundations of mechanical and thermal measurements for various types of materials. Acquisition of theoretical and operational capabilities needed to carry out experimental tests oriented to the estimation of the elastic parameters of traditional, biological and biomedical materials.Knowledge of the principles of operation of main 3D printing technologies and gain skills across the entire prototyping process, from creating virtual models (through CAD drawing and medical image reconstruction) to generating code for printing. Obtain expertise on the mechanical characterization of 3D printed materials, in particular for the FDM technology. General notions of medical image processing for the extraction of mechanical properties.
