“…Multiple software implementations have been developed for modeling cellular structures, each offering unique features and capabilities. For instance, the work by Moj et al [67] focuses on developing workflows for designing strength test specimens using DMLS/SLM and SLS technologies. This approach emphasizes the importance of obtaining a real solid model of the specimens, showcasing the software's capability in handling both the design and manufacturing aspects of cellular structures Furthermore, Liu et al [68] introduced a novel rectangular-circular grid-filling pattern for fused deposition modeling in cellular structures.…”

Purpose Additive manufacturing (AM), a rapidly evolving paradigm, has shown significant advantages over traditional subtractive processing routines by allowing for the custom creation of structural components with enhanced performance. Numerous studies have shown that the technical qualities of AM components are profoundly affected by the discovery of novel metastable substructures in diverse alloys. Therefore, the purpose of this study is to determine the effect of cell structure parameters on its mechanical response. Design/methodology/approach Initially, a methodology was suggested for testing porous materials, focusing on static tensile testing. For a qualitative evaluation of the cellular structures produced, computed tomography (CT) was used. Then, the CT scanner was used to analyze a sample and determine its actual relative density, as well as perform a detailed geometric analysis. Findings The experimental research demonstrates that the mechanical properties of a cell’s structure are significantly influenced by its shape during formation. It was also determined that using selective laser melting to produce cell structures with a minimum single-cell size of approximately 2 mm would be the most appropriate method. Research limitations/implications Further studies of cellular structures for testing their static tensile strength are planned for the future. The study will be carried out for a larger number of samples, taking into account a wider range of cellular structure parameters. An important step will also be the verification of the results of the static tensile test using numerical analysis for the model obtained by CT scanning. Originality/value The fabrication of metallic parts with different cellular structures is very important with a selective laser melted machine. However, the determination of cell size and structure with mechanical properties is quiet novel in this current investigation.
