“…On the other hand, the impacts of volume fraction/ratio of lattice structures were reported by Zhao et al [16] and Monkova et al [25]. Their reports revealed that lattice specimens with a higher volume ratio exhibited superior mechanical properties than those with a lower volume ratio.…”

“…Furthermore, in terms of lattice unit cells, several studies have been conducted by researchers to design unit cells with unique properties. Some of the most commonly employed lattice models are body-centred cubic (BCC), face-centred cubic (FCC), simple cubic, and Kelvin unit cell [23][24][25]. Substantial research efforts have been undertaken to improve and optimise the mechanical properties and performance of lattice structures using the aforementioned lattice models.…”

Additive manufacturing (AM) technology has undergone an evolutionary process from fabricating test products and prototypes to fabricating end-user products—a major contributing factor to this is the continuing research and development in this area. AM offers the unique opportunity to fabricate complex structures with intricate geometry such as the lattice structures. These structures are made up of struts, unit cells, and nodes, and are being used not only in the aerospace industry, but also in the sports technology industry, owing to their superior mechanical properties and performance. This paper provides a comprehensive review of the mechanical properties and performance of both metallic and non-metallic lattice structures, focusing on compressive behaviour. In particular, optimisation techniques utilised to optimise their mechanical performance are examined, as well the primary factors influencing mechanical properties of lattices, and their failure mechanisms/modes. Important AM limitations regarding lattice structure fabrication are identified from this review, while the paucity of literature regarding material extruded metal-based lattice structures is discussed.

“…In contrast to the authors’ initial already published research [ 48 ], in which only 3 types of structures with one volume ratio V r = 57% were used to assess and compare sound properties, within the presented research a different nozzle size and a different layer height of the applied material were used for the samples production. These technological conditions affect not only the quality of the finished product but also its mechanical properties [ 49 , 50 ]. While in the previous research, a nozzle with a diameter of 0.6 mm and a height of the applied layer of 0.3 mm was employed, in this case, the samples were made with a nozzle with a diameter of 0.4 mm and a layer height of 0.254 mm.…”

Noise has a negative impact on our environment and human health. For this reason, it is necessary to eliminate excessive noise levels. This paper is focused on the study of the sound absorption properties of materials with open-porous structures, which were made of acrylonitrile butadiene styrene (ABS) material using additive technology. Four types of structures (Cartesian, Octagonal, Rhomboid, and Starlit) were evaluated in this work, and every structure was prepared in three different volume ratios of the porosity and three different thicknesses. The sound absorption properties of the investigated ABS specimens were examined utilizing the normal incidence sound absorption and noise reduction coefficients, which were experimentally determined by the transfer function method using a two-microphone acoustic impedance tube. This work deals with various factors that influence the sound absorption performance of four different types of investigated ABS material’s structures. It was found, in this study, that the sound absorption performance of the investigated ABS specimens is strongly affected by different factors, specifically by the structure geometry, material volume ratio, excitation frequency of an acoustic wave, material’s thickness, and air space size behind the tested sound-absorbing materials.

Generative design is one of the most promising means of new product development in the world. It allows formation of organic structures that brings various benefits, e.g. in the form of savings of material and production costs. Generative design includes several types of technology, topological optimization included. The paper addresses the technology of topological optimization implemented on the support part of the 3D printing pad. The result of optimization is the creation of a new, more suitable design concept through the Altair Inspire optimization software.
