Spatial materials for additive manufacturing in civil engineering
Říha, Tomáš ; Apeltauer, Tomáš (referee) ; Podroužek, Jan (advisor)
The bachelor thesis deals with additive manufacturing in the construction industry and with materials used in this field. The first part of the thesis defines the 3D printing, briefly describes the history of this progressive technology and gives an overview of the used methods and technologies. The printing methods are divided according to the physical state of the basic material used for printing. The next part of the thesis presents the possible use of additive manufacturing in the construction industry and an overview of realized projects. Finally, at the end of the theoretical part are introduced materials applicable to additive manufacturing in the construction industry and is defined the concept of spatial materials. Spatial materials are a relatively new term, which is not yet in the literature sufficiently defined. These materials can be used for an application in a space where the structure and the position of their particles can be optimized. They can be applied for the creation of 2D filling structures, which are more useful for geometrically simple and simply loaded constructions. It is preferable to use spatial materials to create 3D structures that are designed to fill numerically optimized structures. These structures are based on the principle of double curvature and on a triply-periodic minimum surface (TPMS). In the practical part of the thesis was created the design of building block filled with 3D gyroid structure, designed for prefabrication by using additive manufacturing in the factory or at the site of construction. This proposal reflects the increasing demand for easy individualization of constructions and building elements. Especially, the demand for the creation of structures and shapes which are topologically optimized with a customized appearance and sufficient strength, all at the customer's request.

Automated design and 3D printing of prototypes for urban engineering
Krutáková, Anna ; Vořechovská, Dita (referee) ; Podroužek, Jan (advisor)
This bachelor thesis deals with automated design and 3D prototype printing for urban engineering. In the first part, there is a general definition of 3D printing, including development and overview of basic technology and materials. It also follows the focus on certain measurement methods and the creation of 3D models. In the second part, the thesis focuses mainly on the use in the building industry and it discusses related topics such as the automatic optimization of the external elements of building elements or objects(shape), the internal topology of these building elements (fill) and the possible inspiration from organic structures. There is also distinguished between terrestrial applications focusing on the production of prefabricated building components and implementation at site. Extraterrestrial autonomous applications discuss the possibilities this technology for colonizing the Moon or Mars. This thesis presents the results of a unique assessment of the current state of the art in the field of applicability of 3D technology for additive production in the context of urban engineering and demonstrates the associated advantages and open problems on many examples. Finally, the benefits of this technology are evaluated.

Radial turbine runner design with reduced moment of inertia
Votava, Ondřej ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
This master’s thesis deals with topological optimization of the impeller of a radial turbocharger turbine. It focuses on reducing the moment of inertia with unchanged aerodynamic properties. The optimization was carried out using CFD, thermal and structural analysis. The computational modeling was performed using the finite element analysis in ANSYS. The work proposes models of the impeller with the topological modification of the internal structure. Based on the values of moment of inertia, the stress and the strain the most suitable model was selected.

Multi-material topology optimization of the vibrating beam
Kordula, Tomáš ; Ševeček, Oldřich (referee) ; Lošák, Petr (advisor)
The master‘s thesis deals with optimization of continuum consisting of one or more different materials loaded statically or dynamically. The thesis aims on minimum compliance design and maximum eigen frequency design. For solution of each problem situation are written computational programmes in Python language itself and also as combination with commercial software ANSYS APDL.
