“…However, from Figure 10, it can be observed that the results observed from the present work do show a similar trend, like the other works from Ashby et al [20], Murr et al [21], and Chang et al [22], within the experimental limits.…”

“…The results from their experiments, as well as the results from this work, are displayed in Figure 10. The results from Cheng et al [22] and Murr et al [21] slightly vary from those of Gibson and Ashby [20], where Cheng et al [22] found a dependency for the elastic Young's modulus:…”

“…This second model was described by Ashby [20]. Other authors have also produced similar lattice structures, like Murr et al [21], who used the technique of electron beam melting to melt comparable structures out of titanium and CoCr powder and tested them under compression [21]. Cheng et al [22], on the other hand, has produced structures out of Ti-6Al-4V [22].…”

Abstract:The compression behavior of different 316L steel cellular dodecahedron structures with different density values were studied. The 316L steel structures produced using the selective laser melting process has four different geometries: single unit cells with and without the addition of base plates beneath and on top, and sandwich structures with multiple unit cells with different unit cell sizes. The relation between the relative compressive strength and the relative density was compared using different Gibson-Ashby models and with other published reports. The different aspects of the deformation and the mechanical properties were evaluated and the deformation at distinct loading levels was recorded. Finite element method (FEM) simulations were carried out with the defined structures and the mechanical testing results were compared. The calculated theory, simulation estimation, and the observed experimental results are in good agreement.

“…Electron Beam Melting (EBM) is a type of additive manufacturing which has recently attracted much attention for its potential to produce highly regular metallic lattices [10,11]. Over the last few years several types of uniform lattices have been built using EBM and similar techniques.…”

Electron Beam Melting (EBM) is an AdditiveManufacturing technique which can be used to fabricate complex structures from alloys such as Ti6Al4V, for example for orthopaedic applications. Here we describe the use of EBM for the fabrication of a novel Ti6Al4V structure of a regular diamond lattice incorporating graded porosity, achieved via changes in the strut cross section thickness. Scanning Electron Microscopy and micro computed tomography analysis confirmed that generally EBM reproduced the CAD design of the lattice well, although at smaller strut sizes the fabricated lattice produced thicker struts than the model. Mechanical characterisation of the lattice in uniaxial compression showed that its behaviour under compression along the direction of gradation can be predicted to good accuracy with a simple rule of mixtures approach, knowing the properties and the behaviour of its constituent layers.
