Design of 3D printer for high strength materials
Žlebek, Michal ; Dočkal, Aleš (referee) ; Koutný, Daniel (advisor)
Thesis deals with FDM 3D printing method and testing capabilities of optimum printing conditions for different materials. The aim of this work is to design and manufacture of experimental device that enables printing to investigate these conditions. A device designed in this work was named UK3DP and allows dual color object printing with maximum dimensions of the square base of 150 mm and a height of 150 mm. Before printing, the user can set almost all parameters affecting the printing process, including air temperature in heated chamber that is part of it. To verify the functionality several materials are tested, including ABS, PC and PEI. It also describes basic verification of the influence of selected parameters on the print result. Performs tensile tests confirming the influence of ambient temperature during printing on the quality of fiber connections, examines the final quality of the surface for each layer height and compares the resulting deformation of printed objects with other printers. The result of this work is a 3D printer capable of testing printing conditions for both existing and new types of materials with a range of user adjustable parameters.

A car prototype manufacture using modern methods and CAD/CAM
Horák, Aleš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method. Verification of the results was performed on a vertical milling cantilever FV 25 CNC with control system Heidenhain iTNC 530 using a cutting strategies by PowerMILL CAM software. At the end of the resulting models edit as necessary.

Application of modern technologies for manufacturing models of hedgehog in the cage puzzle
Dratva, Jakub ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The objective of the bachelor thesis is the designing and manufacturing of so called a hedgehog in the cage puzzle model. Individual moulds and dimensions of puzzle were designed in the 3D parametric software Autodesk Inventor. The puzzle model was manufactured by Fused Deposition Modeling method using 3D printer uPrint. The part of the project was manufacturing the silicone mould that will be used to cast the required number of the cage made of commercially available material (plastic). The work was finished with technical and economic evaluation with the subsequent analysis and overall assessment of applied technology.

Manufacturing of Components Using Rapid Prototyping
Peňáz, Jan ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with solution of manufacturing prototype using three technologies. Two of them are additive technologies using principles of Laminated object manufacturing and Fused deposition modelling. The third technology was milling. Model of reversible turbine was used as a base for manufacturing. CAD system SolidWorks was used for the model creation, where output formats were SLDPRT and STL. For error check of STL data software MiniMagics was used. For preparation of 3D printing data softwares SD View and Catalyst EX were used. CAM system SolidCAM was used for creation of machining strategy. Devices used for manufacturing of prototypes were 3D printer Solido SD 300 Pro, 3D printer Stratasys uPrint and 5axis mill Hermle C20U. Print on 3D printer Stratasys uPrint the most advantageous technology for manufacturing one prototype.

Prototype part and made by method rapid prototyping
Kočárek, Karel ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is dealing with prototype stage during development of reduction part for gas flow control, which is positioned in gas boiler downstream of the valve. Thesis is focused on additive manufacturing. Basic technologies, their attributes and procedures which are necessary to be followed are described here. Practical part is composed of 3D model creation in CAD software, export of model to STL format and its inspection for compactness. After that 3D model is sent to printer and functional components are made, that can be used for application verification and for detection of possible design deficiencies before the mold assembly is made.
