Possibilities of using aditive technologies in direct manufacturing of foundry moulds
Herzán, Jiří ; Šlajs, Jan (referee) ; Horáček, Milan (advisor)
The bachelor thesis deals with the production of foundry molds with using additive technologies. At first, the additive technologies are distributed according to ASTM (American Society for Testing and Materials) and subsequently according to the state of the base material. Then, three types of technologies, that can be manufactured by Rapid Prototyping are described. The last chapter of the bachelor thesis is a real example of the production of a prototype fan casting from aluminum alloy AlSi9Cu3(Fe), which was casted into a printed mold by “3D Sand Printing” technology. Based on the obtained data were assessed technical, time and cost parameters of manufacturing the fan. The findings were compared with the molding technology of the ordinary printed pattern, which is an alternative to prototype production. The casting of the fan was cast in Armatmetal s.r.o. in Olomouc.

Application of rapid prototyping in foundry industry
Krejčí, Zbyněk ; Macků, Martin (referee) ; Kosour, Vojtěch (advisor)
These bachelor thesis deals with the practical aplication of rapid prototyping at foundry industry. In the first part of the thesis is given list of the most important methods of rapid prototyping, those principles, advantages and disadvantages. And the second part is dealing with aplication of these methods at foundry industry, and its evaluation.

Application of 3D printing for Lost Foam technology
Kelbl, Michal ; Krutiš, Vladimír (referee) ; Záděra, Antonín (advisor)
This bachelor thesis is focused on application of 3D print by evaporative pattern casting process. The theoretical part includes introduction to evaporative pattern casting process including processes Lost Foam, Full Mould and Replicast®. The practical part is focused on manufacturing of casting using evaporative pattern casting technology with the use of additive technologies for manufacturing of evaporative pattern. Furthermore, are evaluated manufactured castings.

Casting production - Full mould technology
Lekeš, Petr ; Bořil, Petr (referee) ; Pernica, Vítězslav (advisor)
The aim of this thesis is to elaborate a complete study on the topic of production of castings by a evaporation pattern and the apply my knowledge I gained from completing this thesis and make my own cast. Based on the assigment the thesis is devided into two parts, where the first part is focused on the problems of production by this technology, from creating the evaporable pattern, through modern technologies used for this method of casting, to possible defects in the cast, which are connected with this method. In the second part is described the process of making the experimental cast. The result of this work was the familiarization with this unconventional method of casting and the evaluation of its application in today’s foundry industry, as a full-value alternative for common casting technologies.

Production of castings by the Full-Mold casting using 3D printed models
Svoboda, Jaroslav ; Jelínek, Radim (referee) ; Bořil, Petr (advisor)
The aim of the work is to produce a casting using the evaporable model method with the use of 3D printed models. First, the thesis conducts a research on the topic and then discusses the process of producing a casting using this method. The PRUSA MK3S+ 3D FDM printer was chosen for the production of the model and HIPS and PMMA filaments were selected. This is followed by the selection of a model coating suitable for this technology, moulding into non-permanent sand moulds and casting the models. Finally, the final surfaces of the cast models with and without coating are compared.

Rapid prototyping methods (RP) suitable for foundry technology
Slovák, Vojtěch ; Helán, Jiří (referee) ; Horáček, Milan (advisor)
The aim of this thesis is to make an integrated view of the most considerable current Rapid prototyping methods and the most frequent applications in the foundry industry. The work does not propose to find all existing Rapid prototyping methods and their use in the foundry technology either. But it wants to take down the most important aplications of Rapid prototyping methods especially direct casting methods.

Foundry technologies from the point of view of castings accuracy
Hýbal, Ondřej ; Vašťák, Patrik (referee) ; Horáček, Milan (advisor)
This bachelor’s thesis deals with various casting technologies, specifically about investment casting technology, evaporative-pattern casting and die casting. These technologies compares not only on achieving the smallest dimensional tolerances of the final casts, but also of other factors such as surface roughness, wall thickness and production economics. This thesis also describes casting accuracy in general and informs about the management strategy of Six Sigma.

Application of rapid prototyping technology in the investment casting technology
Čejka, Libor ; Mikulka, Vít (referee) ; Kosour, Vojtěch (advisor)
To accelerate the production of prototype castings, it is necessary to shorten the time required for the production of investment casting, allowing just the Rapid Prototyping technology. This technology is being developed for several decades, but the application of the method of lost wax model is completely normal. Task of the thesis is to develop a literature search possibilities of mapping technology in Rapid Prototyping technology foundry investment casting wax model.
