Surface changes based on FDM printing parameters
Čada, Jiří ; Sliwková, Petra (referee) ; Zemčík, Oskar (advisor)
This thesis deals with a construction of modified RepRap 3D printer Rebel II which operates with Fused Deposition Modeling technology and selection of suitable criterion for printing. It mainly focuses on the temperature of the material being printed and speed of printing for three selected materials. Materials were selected based on availability in the market and their application. An experiment, focusing on surface changes of products as well as on the look of a fibre after passing through a nozzle, was performed.

The Red Queen
Králík, Martin ; Zálešák, Jan (referee) ; Gabriel, Michal (advisor)
Red Queen is a chess piece on the story of Alice in Wonderland, which is constantly running to hold it in place, because the world around it is constantly in motion. Therefore, it is a symbol of the theory of evolution, a constant necessity innovation and the eternal escape from competitors. Red Queen's Race is constructed into a miniature civilization, or rather one growing superorganism, which constantly oscillates between the digital and the physical world. The main consciousness of this association is black majestically looking server that supplies with his computing power and energy all attached printers. They are designed specifically for this purpose, such as abstraction of robotics industry, with an emphasis on a functionally aesthetic form, in yellow-orange color of heavy industrial machinery. The most important and largest part of this system, are entities which printers materialize. They are created according to a living creature of this world, generated by computer, based on a unique code, which is the result of calculating the evolutionary recombination, processed by the server, depending on the reactions of outside observers at the objects which are already created. Sense of each entity is attract attention. How much more, the greater is the chance to continue their code in future generations.

Simple 3D Printer Simulator
Čillo, Vladimír ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis deals with design and implementation of 3D printer simulator in C++ using Qt. The simulator assumes a printer based on widely used method of 3D print - Fused Deposition Modeling. An input of simulator is a 3D model in STL file format. For the 3D model simulator provides an estimate of the total print time. Simulation also includes visualization of 3D print. The result is a cross-plaform program tested under Linux and Windows. Functionality of simulator has been tested by several experiments.

The Folk Costumes
Župková, Ilona ; Maixner, Miroslav (referee) ; Gabriel, Michal (advisor)
The outcome of my thesis is airy relief in the form of a spreaded Kyjov´s women's folk costumes. It is made up of embroidery and lace, which gets their original lightness without underlying substance.The white color, I have used, strenghts this feeling. All parts are printed by the ABS plastic. I follow the transformation of hand-made embroidery on the machine-made one with this. 3D printing is another entirely fictitious step for me. Just as the embroidery machine adjusts stitches according to their outline, as well as 3D printer has its own structure of applying material.

Reliefs
Horčicová, Monika ; Sedlák, Jan (referee) ; Gabriel, Michal (advisor)
This master´s thesis consists of three relief objects composed from femur bones. The first relief object is geodetic structure applied to the shape of a sphere. The following two are deformed by softening the material from which they are cast. The second relief object also works with geometry (a square at the base) and systematic folding bones according to a clear order. The third relief can directly interfere with the viewer - the individual femurs contain every two magnets and therefore can move freely with them after the metal plate.

Design and production of experimental axle part
Volfík, Jiří ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The content of this diploma thesis is a design of construction and selection of suitable material for upper-carrier part used for racing vehicle, produced by FDM 3D printing with the alternative option to replace an existing part, which was produced by conventional technique of CNC machining. Various versions of the experimental part are analyzed by FEM and compared in terms of safety coefficient with target to select the most appropriate construction design. The chosen version of the model is at the end compared with already existing part, which was also analyzed by FEM.

Hobby cnc milling machine
Pospíšil, Jiří ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
This diploma thesis serves as experimental proof of real world capabilities of computer designed hobby CNC milling machine with its parts printed on a 3D printer. First half is a brief introduction of CNC technologies to non-professional audience. Second part together with 3D model works as manual to build your own machine. Priority was to keep costs to minimum with decent accuracy still in mind.

Universal ethernet module
Řeháček, Tomáš ; Valach, Soběslav (referee) ; Burian, František (advisor)
This master’s thesis deals with creating a universal module with Ethernet interface and its using for digital values measurement. The main module components are gate array FPGA, microprocessor, PHY chip and RJ45 connector. Printed circuit board is in this thesis designed in Eagle. The chase for board is drawn in SketchUp and printed on a 3D printer. There is a code implemented in created universal module that is performing the function of logic analyzer. Data measured by the analyzer are sent to the Ethernet using UDP/IPv4 protocol. The last part is creating an application in C# to display the measured waveforms on a PC.

Design of delta pi 3D printer with tempered bed using CAE systems
Koudela, Ondřej ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master's thesis deals with 3D printing using non-commercial 3D RepRap type printers. This work briefly describes development trends of non-commercial RepRap printers, theory of FDM print with analysis and comparison of materials, which are used in printing and the issue of the finite volume method and theory of heat diffusion. The practical part based on simulations from SolidWorks Flow Simulation discussed two basic methods of heating hot bed, then the temperature profile of hot end and the heat flow in full assembly of the printer. Outcome of this work is design an optimized model and the physical assembly of 3D printer delta pi type.

Analysis of temperature profile of 3D printer hot bed and hot end by using CAE
Severa, Tomáš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master‘s thesis deals with 3D printing for non-commercial RepRap 3D printer type and materials used in printing. The outcome of this work is a brief introduction to 3D printing, the theory of heat transfer and analysis of the two most important parts of the printer hot bed and hot end. To analyze and optimize the temperature profile of the hot bed and hot end are used Computer Aided Engineering systems CAD and CAE, SolidWorks and SolidWorks Flow Simulation.
