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.

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.

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.

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

Master´s thesis deals with desing of a heated bed for FDM 3D printer using the finite element method. It is briefly described the history of RepRap printers, construction and mechanical parts. Are discussed two methods of heating, heated by PCB boards and using power resistors. Furthermore is work closely focused on power resistors. There are presented methods and procedures which leads to an optimal distribution of heated components on the board of heated bed. In conclusion are presented results of testing which are compared with the simulations in ANSYS.

The matter of this thesis is to find the influence of the diameter of the nozzle on the 3D printer´s print quality. The first part briefly characterizes the Rapid Prototyping technology and describes the RepRap project. The second part describes the construction of the experimental FMD 3D printer. The following section deals with technical printing parametres and their influence on the printed product. The experimental part of the thesis is focused on the impact of the discharge nozzle diameter on the mechanical properties, surface quality and shape accuracy of the final product and on the following recommendations of operational parametres.

The result of this thesis is to create an overview of available 3D printing technologies, design a 3D FDM printer, create an instructional manual on the assembling and create a business model of a 3D printing company.

Master thesis deals with topic about 3D printers, concretely making hardware of control and power electronic for FDM 3D printer. The work could offer an overview about basic 3D printing technologies after reading. More information could be read about FDM technology, which is used in our printer, also with description of all important components. The furthest is discussed about electronic drives. If reader is interested in this topic, part of this thesis is schematic design of control electronics, which can be used to build own boards. Design of printed circuit boards is not present in attachment and can be obtained by contacting the author. For own control is used one of the open source control software. Mechanical problems and also mechanical design is done in parallel thesis by other student of Faculty of mechanical engineering.

This master thesis is focused on a research in the field of 3D printing technology. During the research a particular technology, being regularly applied by the RepRap printers, is described. Mentioned technology is tested on a Rebel II printer model. The findings are applied to the dual 3D extruder design project. This dual 3D extruder is designed and made in two basic options, where the first option discovers the shortcomings and the second option is modified and tested. In the following step, assessment of applicability, functionality, as well as economic analysis of production of this dual 3D extruder is made.

The aim of the work is to design and manufacture a mechanism for setting up and clamping the replaceable head of a 3D FDM printer. The first part of the thesis deals with 3D printing in general, the second part describes the FDM method. Part three is devoted to the selection and construction of a suitable 3D printer, the fourth part to the actual design of the head attachment. In the fifth part, a technical and economic evaluation is carried out.
