“…Due to this variety of parameters, Young's modulus and compressive strength range in quite a broad interval at constant density. Therefore, the properties of the structures investigated in the present work are comparable to those of the cubic structures reported by Kadkhodapour et al11)…”

The compression Young's modulus and strength of lattice structures with porosity between 47.8% and 82.6% produced by Selective Laser Melting (SLM) of a Ti6Al4V powder were investigated. The Young's modulus and yield strength range from 1 GPa to 20 GPa and from 10 MPa to 250 MPa, respectively. On increasing porosity, both stiffness and strength decrease. When porosity increases above 60-65%, the strength shows an accentuated decrease compared to the stiffness decrease. The absence of struts parallel to the loading direction in the lattice structure allows to achieve higher yield strength than other structures having the same Young's modulus.

The present study aims to carry out an experimental, analytical and numerical investigation of the monotonic and fatigue performance of electron beam melted Ti-6Al-4V structures. Therefore, tensile tests, multiple step tests and strain-life tests were performed on machined EBM Ti-6Al-4V solid samples. An elastic-plastic material model in combination with a numerical damage model was examined according to the experimental tensile tests. Analytical models proposed by Ramberg and Osgood, as well as Coffin and Manson were obtained to describe the cyclic stress-strain curves and strain-life curves, respectively. The fracture surfaces of the tested samples and the influence of different build directions were analyzed. A prediction of the static and fatigue material properties is of particular importance, e.g., for the safe application of additively manufactured load-bearing implant structures. Based on the determined analytical and numerical models, the material and product behavior of complex electron beam melted structures under cyclic loading and fatigue life determination can be investigated in the early stages of the product development process.

“…The compression strength was respectively in the range 6.5-81.3 MPa and 4.6-69.2 MPa. Kadkhodapour et al [40] presented structure-property relations for Ti6Al4V scaffolds based on F-RD and I-WP unit cell. Cellular lattices were manufactured at different volume fractions: 30% and 45% for I-WP-based cellular lattice and 45% for F-RD-based cellular lattice.…”

Selective laser melting technology makes it possible to produce 3D cellular lattice structures with controlled porosity. The paper reflects to machining and examination of structures with predefined distribution, shape and size of the pores. In the study, the porous structures of Ti6Al4V were investigated. The tests were carried out using structures of spatial architecture of Schwarz D TPMS geometry with a total porosity of 60% and 80% and various pore sizes. Dimensional accuracy of additively manufactured structures was measured in relation to the 3D model. Geometry of the final structure differed from the CAD model in the range ± 0.3 mm. The surface morphology and porosity of the solid struts were also checked. The mechanical properties of the structures were determined in a static compression test.
