“…In addition to this, the product of topology optimization includes bionic shapes that can be utilized from both a functional and an aesthetic point. In topology optimization, shapes are generated directly and specifically for a specific case [4,5,6]. Furthermore the designer can reduce the weight and improve the performance of the designed components by using a complex mesh for the filling of the designed component.…”

“…The properties of the filling can be focused for example on absorbing impact energy, dampening vibrations and noise. [5,6] To implement topology optimization during component design must the designer pre-specify certain constraints for the designed component such as required geometric properties, component weight, load conditions and material. [5] The material is used only where it is necessary due to the boundary conditions.…”

“…The material is defined only where it fulfils its purpose in terms of mechanical properties. [5,6] Compared to conventional components this technology enables the designing of parts with surfaces that are difficult to define mathematically. The result of the optimization can be a component with a complex shape that would be difficult to manufacture.…”

“…In practice these parts cannot be produced without simultaneous five-axis milling and in many cases it is necessary to use additive manufacturing technology because they cannot be produced by other technology. [6,7] Additive manufacturing (AM) is also known as ``rapid prototyping'' or three-dimensional printing (3D printing). Additive manufacturing is a technology for manufacturing components from a 3D model which is based on connecting materials layer by layer.…”

There is a lot of applications for manipulating industrial robots nowadays. Maximizing the tasks that can be assigned to robot manipulators is one of the criteria for deciding if their application is appropriate. The article discusses the topology optimization of the gripping jaws of an industrial robot to reduce the jaws' weight. The previously used gripping element made of C50E steel was optimized to reduce the weight of the jaws. Shape optimization was performed based on analysis from CAD programs Inventor Professional 2022, Autodesk Fusion 360, and Ansys Discovery. The new jaws were manufactured by the additive technology of selective laser sintering (SLS) from PA12 material. The optimization resulted in a significant reduction in weight compared to the original jaws. As a result of optimizing the weight of the designed jaws, it was possible to increase the weight of the object of manipulation.

“…However, apart from the process shortcomings mentioned, additive manufacturing (AM) offers advantages such as weight optimization, complex geometries, material savings, environmental friendliness, etc. [ 11 , 12 ]. In terms of the final product, AM is limited by the size of the object dimensions.…”

This work is focused on the influence of heat treatment of a part produced by the SLM (selective laser melting) method of stainless steel, 316L. Two heat treatment regimens were tested and compared with the state without heat treatment. Subsequently, TIG (tungsten inert gas) welds were created on the base materials processed in this way. All welds were subjected to mechanical tests and microstructural analysis. The tensile test was performed both for the welded joint and for the base material in the transverse and longitudinal directions. The tensile strength values of the samples with the welded joint were compared with the values required for the base material, 316L forged steel (1.4404). Microstructural analysis revealed significant differences between samples with and without heat treatment. The results of these tests are supported by SEM analysis. EDAX (energy dispersive analysis of X-rays) semiquantitative analysis confirmed the presence of ultra-fine pores in the structure. The results of mechanical tests show that the solution annealing at 1040 °C for 0.5 h gives better results than the same heat treatment with a duration of 2 h.

This research aims at enhancing the performance of scale-model scooter decks by investigating various architected cellular metamaterial and bio-inspired core structure designs, such as honeycomb, tetrachiral, re-entrant, arrowhead, and star-shaped arrangements. An initial effort is made toward the design and rapid prototyping of small-scale deck with a uniform honeycomb core structure. More specifically, polylactic acid is utilized to fabricate complex structures via fused filament fabrication technique. Investigation is then focused on its mechanical performance, such as its bending properties obtained through a three-point bending test. Simulations are also conducted with different core configurations using a geometrically non-linear finite element method which is implemented. Experiments are carried out to verify the numerical results. After validation, various patterns are modeled, and eventually, it is observed that the functionally graded arrowhead structure has the best bending resistance, compared to other bio-inspired and mechanical metamaterial structures. At a constant force of 845 N, the functionally graded arrowhead design lowers the deflection in the middle of the scale model of scooter deck by up to 14.7%, compared to the uniform arrowhead structure. Furthermore, comparing the tetrachiral and functionally graded arrowhead configurations at a constant force, a 30% reduction in central deflection was observed. Due to the lack of similar results and designs in the specialized literature, this work could potentially advance the state-of-the-art scooter core designs and provide designers with architectures that could enhance the performance and safety of scooters.
