“…This distribution reflects specific loads, limitations, production limits, and performance requirements. The use of the established function for optimal distribution of material results in the solution of binary problems of optimized areas [17][18][19][20]. The answer is that for each element there is a relative density, the value of which can range between p min , i.e., the minimum allowable density value for elements greater than 0, up to 1.…”

The application of topological optimization is currently considered one of the current trends. Because the shape of the components thus designed is the result of a design generated based on external influences acting on the model, their form can be considered almost optimal. For example, the extent of material savings resulting from shortening production cycles and reducing energy requirements is significant. Due to the way models are produced by layering the material in 3D printing, this technology makes it possible to get a little closer to the models’ optimal shape, for example, to produce prototype models for the production of injection moulds. The amazing amount of plastic and composite materials that this technology brings allows for a variable change in manufactured models based on requirements or external influences. These materials also include a group of materials and composite materials that are classified as biodegradable due to their composition. This fact, combined with the possibility of achieving the most optimal shape of components, contributes to reducing the environmental burden of such oriented production. This work presents the opportunities for modifying topological optimization outputs based on operating parameters and limits of additive production equipment fused deposition modeling (FDM). It gives the possibilities of using alternative ecological materials, their direct application, and the impact on creating models with the help of this technology. The final phase represents the result of the optimization process of the subsystem mechanism and the influence of the mechanical properties of biodegradable materials on the production process and the energy intensity of production. The aim of this work is to point out the fact and possibilities of using composite materials on a natural basis and their possible impact on reducing the environmental burden.

“…This method is used in cases where it is necessary to design or modify a model to be located in a particular place, withstand predefined forces, or relieve it. Topological optimization is thus a way of creating components from complex blocks [19]. Their final shape is the result of parameters defined before the process itself.…”

“…These technologies include topology optimization, biomimicry, experimental design methods ,and lattice structure creation. 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).…”

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.

The article deals with the development of the construction of a second generation robotic manipulator designed on a modular principle. The manipulator consists of 6 separate rotary modules interconnected by passive members of the structure. In previous generations of the module, the high weight of the overall assembly, which limited the movement properties, proved to be a problem. Modifications to the structure no longer allowed for further weight reduction. Therefore, a change was made to the materials used for the passive members of the structure. The aluminium alloy was replaced by a continuous carbon fiber reinforced composite produced by additive technology. Modelling and simulation in CAD software was used in the modification of passive members, which was necessary in order to be able to design and manufacture composite parts.
