“…So far, the most developed approaches for applied research in the field of engineering are still related to FEM-based approaches providing reasonable deviations between predicted and validated printed structures and their mechanical properties [101,102], including failure prediction and fracture patterns in different deformation modes [103]. These approaches can result in developing digital twin technologies [104]; it is also important to involve multiscale simulations to account for microstructure and crystallographic texture effects which can be an issue for HCP materials [105].…”

We overview recent findings achieved in the field of model-driven development of additively manufactured porous materials for the development of a new generation of bioactive implants for orthopedic applications. Porous structures produced from biocompatible titanium alloys using selective laser melting can present a promising material to design scaffolds with regulated mechanical properties and with the capacity to be loaded with pharmaceutical products. Adjusting pore geometry, one could control elastic modulus and strength/fatigue properties of the engineered structures to be compatible with bone tissues, thus preventing the stress shield effect when replacing a diseased bone fragment. Adsorption of medicals by internal spaces would make it possible to emit the antibiotic and anti-tumor agents into surrounding tissues. The developed internal porosity and surface roughness can provide the desired vascularization and osteointegration. We critically analyze the recent advances in the field featuring model design approaches, virtual testing of the designed structures, capabilities of additive printing of porous structures, biomedical issues of the engineered scaffolds, and so on. Special attention is paid to highlighting the actual problems in the field and the ways of their solutions.

“…The basket‐weave morphology of α / α ′ phases is also an important factor to cause the anisotropic tensile properties of the SLM‐formed Ti6Al4VE alloy. [ 20,21 ] Gao et al [ 22 ] reported that the anisotropy in strength and ductility is mainly dependent on the heat‐affected zone within the sample. In addition to the above reasons, the texture in SLM‐formed Ti6Al4V alloy is also an important reason for the anisotropy of mechanical properties.…”

The effect of texture on the anisotropy of tensile properties of the SLM‐formed and annealed Ti6Al4VE alloy is investigated. The component of microstructure in these alloys is dominated by the α/α′ phase. Furthermore, there is a significant difference in the intensity of X‐ray diffraction peaks between the XY plane that is perpendicular to the build direction (BD) and the XZ plane that is parallel to the BD, though alloys are annealed with the same treatment. Ultimate tensile strength and yield strength in the X direction are higher than in the Z direction and exhibit significant anisotropy in the alloy annealed with the same treatment conditions, but the plasticity presents an opposite trend. The average Schmid factor of the basal <α>, prismatic <α>, and pyramidal slip systems in the alloy is analyzed by electron backscatter diffraction and presents that the prismatic <α> slip is the main deformation mode during the tensile testing. The <0001> fiber texture parallel to the loading direction in the XY plane is stronger than that in the XZ plane and causes a decrease in the number of the basal <α> slip system activating in the XY plane in contrast to the XZ plane.
