The effect of a nozzle channel on printing parameters of FDM 3D printer
Rygl, Filip ; Prokeš, Tomáš (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis follows up the influence of the nozzle channel on different parameters of printing using FDM / FFF method. The first part briefly describes the inclusion of this method in additive technologies. Then follows the description of the device for this involved method, printing parameters and research of used polymer materials. In the next chapter is proposed an experiment to test selected print parameters and there is described used equipment. The following part documents the outputs of the tests, their evaluation and comments.

Sensors for driver assistance systems
Ptáček, Martin ; Čala, Martin (referee) ; Beneš, Petr (advisor)
This bachelor thesis is devoted to vehicle stabilization systems, especially to the Anti-lock Braking System ABS, Anti-Skid Regulation ASR and Electronic Stability Program ESP. The main emphasis is placed on sensors needed for implementation of these systems and their required parameters. Findings learned are applied for the implementation of the stabilization system in the model car of the scale 1:10. The relation between the quality of measured sensor data and quality of the resulting stabilization is analyzed using model platfrom testing.

Possibilities for replication of spraying nozzles by means of 3D printing methods
Petrenec, Jan ; Malý, Milan (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with the possibilities of using additive manufacturing (AM) in case of replication of pressure swirl atomizers in order to reduce the financial costs as well as the production times achieved by the existing production processes. Several goals were set by an assignment of this thesis. In particular, the individual 3D printing methods were discussed in detail and the specific selected type of spray nozzle was introduced, together with their requirements that have been elaborated in detail. The applicability of the individual representatives of AM was also evaluated, and their comparison was made. The result of this work are two potentially useful methods for replicating pressure swirl nozzles, namely Micro Laser Sintering and Direct Metal Laser Sintering. Due to lack of time and the already large extent of this thesis, an optional 6th task was not carried out and the experimental verification of these set conclusions remains a question for further studies.

Tesla's turbine as a source of energy
Šedina, Martin ; Libich, Jiří (referee) ; Kazda, Tomáš (advisor)
The bachelor thesis deals with the currently used types of water turbines and next part of the thesis deals with the theory of Tesla turbine. The theoretical part discusses water wheels, water turbines with their types and models which are described in the work. The thesis also discusses the construction of the Tesla turbine, its possibilities of using, inside principles and information about Tesla´s patent. The practical part contains the design of the Tesla turbine with modifications for increasing efficiency. The thesis describes the technology that the turbine was produced.

The House Anatomy and the Digital Regionalism
Boušková, Linda ; Magnusková, MA et MA Eva (referee) ; Kristek, Jan (advisor)
Robotics and digital design are associated with the creation of free forms. The thesis deals with the potential of new building technologies in the sense of an opportunity to build on the foregoing regional architecture, disconnected by an industrial mass production. A creation that can reinterpret the charm and diversity of Moravian houses, preserving the continuity between old morphology and today’s housing requirements.

Object reproduction with using 3D printing in the hyperbaric environment
Kadlec, Martin ; Vondrášek, David (advisor) ; Dvorský, Jaroslav (referee)
Title: Object reproduction by 3D printing in the hyperbaric environment. Objectives: The bachelor thesis is designed as pilot study examining "Object reproduction by 3D printing in the hyperbaric environment". Its aim is mainly to acquire sufficient knowledge as precursor to further research in this field. Methods: Data was organized into tables and charts (based on proprietary test results). Descriptive methods and inferential statistics (T-test) were used to determine hypothesis. Results: T-test did not determine a statistically significant difference in weight (p = 0.98026) between objects printed at atmospheric pressure (101,7 kPa ± 2 kPa) and objects printed at absolute pressure of 150 kPa ± 3,6 kPa. The weight difference of compared build sets was well within substantive significance threshold limit ≤ 5 %, <0,35 % - 4,37%>. All objects (build sets n1 = 10; n2 = 10) did meet the required criteria in proprietary functionality test, therefore we can assume that fairly affordable 3D printer will be capable of printing in hyperbaric environment ( ≥ 150kPa ± 3,6 kPa) and objects will be able to fulfill their main purpose as well. Even though the results are meaningful, further research is needed. Keywords: 3D printing, 3D digitization, hyperbaric environment, 3D printing in the unusual environment

3D tlač a zmeny na trhu práce
Štefaňáková, Lucia
Following bachelor thesis is concentrating on analysis of possible impacts on forming a new model of labour market due 3D printing technology extension. In the first section are defined basic concepts related to 3D printing, core technologies, but also used materials, which are important for understanding this issue. Essential part of the thesis is to refer methods and the main goal. The next section of the thesis is dealing with the search of available literature, but on the other hand is also talking about processing knowledge and information needed to identify jobs, that might arise or completely disappear because of 3D printing extension.

Návrh nábytkového prvku bez kovových a lepených spojů
Dias, Jiří
The aim of this work was to design a furniture element without metal and glued joints. The thesis is divided into theoretical and practical part. In the first part is the characterization of materials and their processing methods, where the work is dedicated to the conventional method CNC and mostly unconventional technology of 3D printing. The research of constructional solutions of furniture was created afterwards. No glue, nor any metal components was used. The final phase of this work is to design own original constructional solution, which is applied to the storage furniture element - shelving system.
