Manufacturing of a special box using 3D printer
Grünwaldová, Kristýna ; Slaný, Martin (referee) ; Koppová, Aneta (advisor)
This thesis deals with manufacturing of box with locking mechanism by using technology of 3D print. The aim of this thesis is manufacturing a functional model of the box, what will be used in escape games. The sequence of stages what leads to manufacture the model is descibed in the thesis. First the suitable technology and material for 3D print had to be assessed and selected. Then the model was created in software Inventor according to input parameters. This 3D model was processed to STL formate and then was produced the G-code for a printer from PrusaSlicer programe. Parts of the box were printed and assembled and then the functionality of them was assessed.

Manufacture of nut tightening device for reactor cooling pump's impeller
Rygl, Filip ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This thesis solves the problem of design and production of a special mounting device for the impeller nut of the main circulation pump GCN-317. The proposed device is intended to solve the problems associated with the mounting and dismounting of this nut. The work provides basic information about the Dukovany Nuclear Power Plant and VVER-440 systems in general, including their brief history. It also introduces the operational and legislative environment of the primary circuit of the nuclear power plant. It deals with the task and technical description of the main circulation pump and its overhaul. The following sections present the basic principles of construction of the device and an overview of its components with a description of their purpose and method of production. The last part of the thesis describes the function of the device and its verification and reports on its deployment.

Production of prototype mold parts using rapid prototyping methods
Kaloda, Vít ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The diploma thesis pointed out the possibility of using rapid prototyping methods in the field of plastic injection, specifically to make shaped inserts into the injection mold. The universal frame of the injection mold was used and only the shaped inserts were changed. The main part of the work was the construction of an injection mold with the subsequent practical production of shaped inserts for a specified part. In the introductory part, a theoretical search was performed, about which production methods in combination with suitable materials could be theoretically used. Furthermore, the polyjet and DLP methods were chosen, which were used to produce components (core and cavity). The result of the diploma thesis was a summary of all parameters, comparison of materials and production methods. Polypropylene and polyamide 6 materials were injected into the injection mold, from which the first prototype products were made. Instructions for the production of shaped inserts with the recommended technology and material were created for the selected type, which could be used in practice.

Technology of manufacturing of carbon fibre composites by hot forming
Přikryl, Pavel ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This master’s thesis deals with the composite materials and especially aims on the carbon and glass fiber composites. It points out different composition types and manufacturing methods which reflect in the different mechanical properties, final quality of the manufactured part and also in the manufacturing time. The practical part includes two particular manufacturing methods using prepregs, one cured in an autoclave and one by hot compression moulding.

Production of threads in thin-walled parts
Václavek, Petr ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
The aim of this bachelor thesis is to describe and compare technologies used in a production of threads in thin-walled parts. It includes descriptions of commonly used materials for these parts and their qualities, that may have an influence on the thread production. The following are the descriptions of different methods of manufacturing threads directly into thin walls, forming different types of bushings and anchoring threaded fasteners. Special focus is on a comprehensive analysis of processes of welding, riveting and pressing nuts. The technological and economic suitability of each solution is then compared.
