Application of modern technologies for the production of spare parts airsoft guns
Král, Ondřej ; Zemčík, Oskar (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis describes design and manufacture of airsoft spare parts. Selected spare parts were hammer and spring holder, which were designed in 3D parametric software Autodesk Inventor 2016. Chosen method to manufacture spare parts, was Fused Modeling Deposition, which is part of Rapid Prototyping technology. The device for producing parts was 3D printer uPrint. The manufacture of silicon mould was based on printed spring holder, which was used for parts manufacture, by casting plastic materiál. Thesis is completed with a technical-economical evaluation, in which it was found that the silicon mould casting is more profitable in the production of more parts.

Design of Stirling Engine Operating at Low Temperature Difference
Gavač, Adam ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
The aim of this study is to acquaint the reader with the Stirling engine, which is one of the possible alternatives to generally known combustion engine. The theoretical part has three major purposes: First is to describe thermodynamics of the Stirling cycle in the range that is essential for comprehension of the engine`s operating principle. Second is to mathematicaly derivate expression for the efficiency of the ideal Stirling cycle. Third is to discuss each of the essential parts of the device. Concepts acquired in the theoretical part were employed to design a digital model in the parametric modeler Autodesk Inventor. Parts were manufactured by a combination of typical and progressive technologies. Engine was assembled and tested afterwards.

Production of planetary gear set model on 3D FDM printer
Magdon, Jan ; Prokeš, Tomáš (referee) ; Zemčík, Oskar (advisor)
This Bachelor's Thesis is looking into designing of a planetary gearbox then subsequent production with using the Fused Deposition Modeling (FDM) technology. The first part describes the production process using additive technologies, focusing mainly on FDM technology with properties of materials used in this method, then the theory of planetary gears with their practical use. The second part is devoted to production of model planetary gearbox, which is designed with regard to possibilities of FDM printer. Single parts were designed in 3D programme Autodesk Inventor Professional 2016. Finally the product is evaluated technically and economically.

Assembling and Functional Verification of a Home 3D Printer
Tesař, Jaroslav ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
This thesis was created as a bachelor project in the Faculty of Mechanical Engineering at VUT in Brno. In the theoretical part, the additive technology Rapid Prototyping is introduced together with the most common methods, followed by the assessment of advantages and disadvantages of the new technology and its possible uses in various fields of human activity. In the experimental part of the diploma thesis was assembled and the printing parameters were set. Consequently the comparison models were printed on the 3D home printer and on professional printer Dimension uPrint. The accuracy of the printers is compared. The thesis concludes with the analysis of technical and economical parameters.

Recycling plastics for 3D printing
Hellebrand, Martin ; Kolář, Ladislav (referee) ; Zemčík, Oskar (advisor)
Purpose of this paper is analysis of basic Rapid Prototyping technologies including FDM. Technologies are compared in matter of possible recyclation of used materials. The largest recyclation potential appeared in case of FDM technology. There were conducted analysis of basic materials used in this method. Possible methods for recyclation were described. Finally, there were conducted economical analysis to evaluate viability of recyclation in case of FDM.

Production of Preparation Prototype Using Additive Method of Fused Deposition Modelling
Sedláček, Milan ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
This thesis focuses on the production of a product using the increasingly popular additive technologies Rapid Prototyping. The theoretical section explained the very rapid prototyping technology and its application in various sectors. There were also mentioned different materials to use for 3D printing and actual printing method. The practical part was focused on the prototype modeling in SolidWorks CAD software and the subsequent production of elements of the 3D printer uPrint, using additive method Fused Deposition Modeling. In the conclusion, there is the evaluation of prototype production and also cost comparison using alternative materials.

Application of Fused Deposition Modelling Method to Production of Planetary Mechanism Model
Kudláčová, Barbora ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This thesis aims to deal with designing and construction of the planetary mechanisms mod-el with using the technology of Rapid Prototyping. Virtual model was designed by para-metric program SolidWorks 2013 and produced by 3D printer called Dimension uPrint, which uses Fused Deposition Modeling for the production. The thesis also includes the description of the planetary mechanism especially from theoretical, practical and also construction knowledge. The thesis contains the description of Fused Deposition Modeling too. The model of planetary mechanism is using as an educational tool especially for students of BUT Faculty of Mechanical Engineering in the subject Kinematics.
