“…Biomimicry imitates patterns or processes from nature which are then applied in the industry (Pollak et al, 2020). Three main parts in optimization are topology optimization, size optimization, and shape optimization (Pilagatti et al, 2021). The combination of topology optimization and additive manufacturing provides more creative space for the design and manufacture of various components (Kang et al, 2021).The development of the optimization topology was initially shown for 2D problems, then gradually it can be used for 3D integrated with CAD (Cuillière et al, 2018) Compared to conventional manufacturing, process topology optimization gives users the freedom to produce very complex geometries and material compositions (Wang et al, 2021).…”

Sultan wind turbine is one of the products of the New Renewable Energy Engineering Lab, Faculty of Engineering Untirta which has developed from year to year until now. To keep up with industrial developments in today's era, renewal is needed to improve and update the technology contained in the sultan wind turbine. In particular, today's optimization topologies are seen as providing the possibility to realize truly manufacturing-optimized designs through topology optimization. A topological optimization is an approach that is considered powerful in design because it contributes to designs that can save energy, materials ,and time that cannot be achieved economically using other manufacturing processes. A topological optimization, as it is often called, computer configuration of the best material over 3D space, usually represented as a grid, to satisfy or optimize physical parameters. Designers using these automated systems often seek to understand the interaction of physical constraints with the final design and their implications for other physical characteristics. Such understanding is a challenge to using a visualization approach to explore the design solution space. The essence of our new approach is to summarize an ensemble of solutions by automatically selecting a set of examples and parameterizing a design space.

“…In general, there are two approaches which need to be focused on. One approach is the optimization of the geometry [6][7][8][9][10][11] and the other approach is the development of polymer composite material with thermal conductive fillers.

Prototype development nowadays can rarely be imagined without 3D printing. In the fast‐moving electronics industry, 3D printing is a good way to react quickly to changing developments, for example, when it comes to heat sinks made of thermally conductive material. 3D printing of thermally conducting plastics, which are also electrically insulating, is an ideal candidate for the rapid generation of heat sink. Nevertheless, 3D printing also shows some drawbacks in regard to properties of the printed parts, as porosities or layer adhesion, emerging from layer deposition in the process. Therefore, the aim of this work was to investigate the influence of the orientation of fillers on the thermal conductivity of filled polylactic acid (PLA). PLA was filled with amounts of 15–45 wt.% of boron nitride and aluminum granules and printed into heat sinks in two different orientations to investigate this influence on the thermal conductivity. The printed heat sinks were then placed on a heated aluminum block and the thermal transport was examined with an infrared camera. It could be shown that especially with platelet‐shaped fillers such as boron nitride, the orientation of these in the test specimen has a large influence on the thermal conductivity.Highlights 3D printing of thermally conductive heat sinks Thermal characterization of 3D printed heat sinks Computer tomography scans of heat sinks to evaluate the porosity

Thus, additive manufacturing can be used to enable specific optimizations to structures to influence flow in terms of heat transfer and pressure drop, as presented in Alexandersen et al [7], Dede et al [8], and Pilagatti et al [9], among others that are presented in the reviews done by Dbouk et al [10].…”
