Abstract

The paper focuses on developing a complex numerical procedure for 3D-printed titanium alloys utilized for dental implants. An experimental campaign has been organized to study the influence of imperfections found in specimens that reach printing limits. The lower ultimate strength of thinner specimens is assigned to observed higher porosity. The specimens are printed from a powder that contains different-sized spherical particles. Therefore, the lattice discrete particle model, which can take the porosity into account, is used for numerical simulations. The theory of plasticity is utilized on facets defined in the model. Such a numerical tool is crucial for simulating the implant behaviour under different loading conditions and will allow/support a patient-specific design.
