The Analysis of 3D printing use in households
Ureš, Miloslav ; Basl, Josef (advisor) ; Fortinová, Jana (referee)
The diploma thesis called The Analysis of 3D printing use in households is dealing with the current topic of 3D printers and examines the ways of their use in households in the Czech Republic. The main objective is to analyze the use of 3D printing in households. This means to find out why and how often the owners of 3D printers use them in their households. Also, to find out the whole range of other factors related to the ownership of 3D printers such as frequency usage, machine satisfaction, number of owned printers, etc. Based on the analysis for which the data was collected by the questionnaire survey method and later evaluated using hypotheses and comparisons with another similar survey, criteria for 3D printer selection are compiled. These recommendations serve to those who are interested in acquiring this technology. Research conducted in this thesis may be beneficial for future analyzes of this market, or for inventors of 3D printers who are considering to launch their 3D printers on the Czech market.

Innovation of the Rep Rap 3D Printer
Zítka, Lukáš ; Zemčík, Oskar (referee) ; Sedlák, Josef (advisor)
The present Master thesis is focused on innovation and verification of the functionality of a 3D RepRap. The theoretical part of the thesis characterizes individual additive technologies. The practical part is focused on the design of the technical modifications of the printer in order to achieve the quality of the printing, while the current 3D printer design is compared with the innovative solution. The practical part tests the setting of print parameters, various materials for 3D printing and necessary finishing operations. The thesis is completed

CNC router for PCB
Gerják, Rastislav ; Vaculík, Sebastian (referee) ; Vyroubal, Petr (advisor)
In mechanical industry, both additive and subtractive manufacturing methods are controlled by instructions in G-code, making it possible to utilize both technologies in one modular device. Main objective is to design, construct, and calibrate multipurpose machine based on RepRap 3D printer, which will be able to use attached spindle to precisely mill light materials. Particular emphasis is given to ability to carve a pattern and drill holes in plated substrate in order to create functional PCB by incision.

Surface heat treatment after 3D FDM print
Břoušek, Lukáš ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The topic of diploma thesis are surface heat treatments after 3D print by method Fused Deposition Modeling. In the introduction is located recherche of the given issue. Further, we describe the construction and process of the 3D printer construction, on which will be printed samples for experiments in the next part of the thesis. The aim is to determine the behavior and changes of surface structures of heat-affected samples from different materials. Furthermore, the suitability of the used methods and the possibility of their use in practice.

Usage of Modern Technologies for the Design of the Production of Children's Puzzle
Sedláková, Eva ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The bachelor thesis deals with the design and production of children's puzzle using modern methods and technologies. It characterizes the puzzle as a toy and its use, it as well describes the additive Rapid Prototyping technology, commercially available additive materials and their applications. The practical part describes the design of the individual parts of the puzzle in the SolidEdge parameter model and their production on a repro Prusa i3 printer. The last part of the bachelor thesis concerns with a technical- economic evaluation.

3D FDM printer Rebel II and parameters of print
Pištek, Patrik ; Zouhar, Jan (referee) ; Zemčík, Oskar (advisor)
This work deals with a RepRap 3D printer. The introductory chapter describes rebuilding, the reason of the rebuilding and basic components of a 3D printer. The following is a selection of lesser-used materials PETG and nylon. The individual chapters summarized reviews of experimental studies and the types of samples used in the testing of similar machines. Based on this information the author design size and shape of the sample for the second experiment, chosed relevant technological parameters and proposed plan of the experiments. Investigated parameters are temperature of the nozzle and printing speed. Experimental part of this work includes two experiments. In the first experiment, thin-walled objects by width of a single fiber were printed. The surface quality of the fibers was observed under a microscope. The second experiment evaluated the dimensional variations of the samples in dependence on the aforementioned parameters. Samples were scanned at the office 2D scanner and arithmetic mean of surface roughness Ra was measured by roughness meter on the side and top wall of the samples. The results and recommendations of the author are summarized in separate sections. The temperature and speed affected the quality of the surface of extruded fibers. The effect of temperature on the quality of the bond between the fibers has been significant. Print speed heavily influences the dimensional accuracy and deformation of geometric elements of the sample. The effect of temperature on dimensional accuracy was much less pronounced. In discussion part are expressed some ideas for future experiments. The conclusion summarizes all the gains of this work.

Implementation of 3D RepRap Printer
Sochor, Marek ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The aim of the bachelor thesis is build and verify the functionality of the 3D RepRap printer . The printer will be assembled from normally available parts and also 3D printed parts, becouse its main idea of the RepRap. After verifying the functionality of 3D RepRap printer We print identical part on two types of printers (RepRap 3D printer tand uPrint printer) and to evaluate the overall analysis (financially and physical). The work will be completed evaluation of usability and competitiveness assembled RepRap printer in practice and will be carried out, the technic-economic evaluation.
