Utilization of the modern method for a production of the prototype of the hair dryer handle
Vrána, Radek ; Slaný, Martin (referee) ; Sedlák, Josef (advisor)
Aim of this bachelor work is to design and produce two-part universal holder of ETA hair dryers. Holder is designed in 3D CAD system Autodesk Inventor and is produced by Rapid Prototyping technology using Fused Deposition method. From existing Fused Deposition Modeling prototype of bigger visual part is made silicon mold and cast from resin. There is evaluation of both methods considering technical-economical aspects in the end of my work. Process of design and production using both methods is documented and described. My work includes history of ETA, a.s. company, characteristics of Fused Deposition Modeling method and technology of casting to silicon mold. Prototypes will be used for further development of holders for ETA´s hair dryers.

New ways in manufacturing and construction of mould for wax casting
Dostál, Pavel ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
The aim of this work is to compare technology of silicon and aluminium moulds used to make castings using technology of cire perdue with single – piece work. The work itself deals with physical production of silicon mould in vacuum casting system, shaping aluminium mould using CNC machine and subsequent casting of wax models into these moulds. It also handles with physical production of one piece by shaping. It contains background research of the method lost wax casting manufacturing aluminium and silicon moulds and last but not least of Rapid Prototyping technology for producing master model.

Application of modern 3D technologies for production of car key cover
Franc, Tadeáš ; Sedlák, Josef (referee) ; Jaroš, Aleš (advisor)
The aim of this bachelor thesis is a reconstruction of a car key cover by using modern 3D technologies. Computer model was created in Autodesk Inventor Proffesional and the component printed on the 3D printer uPrint Dimension. Printed component also served as a mother model for a mould made of silicon matter, which was afterwards used for casting a plastic component. The outcome of this thesis is a functional car key and a technical-economic evaluation of both of these methods.

Application of Modern Technology for Manufacturing of Prototype Model of Fixation Handle of Keyboard Stand
Rozum, Jakub ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
This thesis is focused on manufacturing of prototype model of fixation handle of keyboard stand using modern vacuum casting technology. The first chapter is focused on product analysis. The following parts of the thesis consist of research dealing with issues of vacuum casting and materials used for this technology, especially casting resins. Part of the thesis is manufacturing of a silicone mold based on already existing component, which is used for the casting of the new component. The silicone mold is made of a silicone mixture Silastic T – 4, for the casting of the new component is selected casting material SG 2000 / Komp. A + B. For vacuum process is used vacuum chamber MK Mini. Bachelor thesis is completed by technical and economic evaluation.

Application of Modern Technologies in Production of Bathroom Accessories
Kudela, Jan ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The aim of this bachelor thesis is to design and manufacture prototypes of selected bathroom accessories. These were designed via 3D parametric modelling in Autodesk Inventor software. CAD models were then 3D printed at Dimension uPrint printer using today’s most common additive technology – Fused Deposition Modelling. A conventional silicon mold was also created as a part of this thesis using printed prototypes and other set of designed accessories was created by resin casting. The conclusion of this thesis is comparison of printing and casting manufacturing processes of these bathroom accessories from the technological and economical point of view and detailed evaluation of used technologies.

Application of Modern Technologies to Concept of Production of Car Part Prototype
Bachorík, Patrik ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The objective of my bachelor thesis is the design and manufacture of a prototype component for automobile industry. Specific designs and parameters of the prototype component were constructed in 3D parametric software Autodesk Inventor. Additive method Fused Deposition Modeling – a 3D printer uPrint was used for the production of the prototype component. A part of my work was the manufacturing of a silicone form with the use of a vacuum – moulding system. The purpose of this form was casting the required number of prototype components made of commercially available materials. Also, metrologic measuring of the pieces was carried out using 3D measuring machine with the aim of evaluation of manufacturing tolerance limits compared to the engineering drawing. The work was finished with technical and economic evaluation of the manufacture process of the prototype component with the subsequent analysis and overall assessment of the most convenient economic variant.

Application of Modern Technologies for Production of Front Part Fastening System Mountaineering Crampons
Samohýl, Lukáš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The aim this bachelor thesis is a production of prototype front part fastening system mountaineering crampons. In this work will be carried out the design and construction of a new prototype parts using the parametric application SolidWorks. For prototype production front part crampons will be used additive method Fused Deposition Modeling - uPrint 3D printer. Part of the work will be production of silicone moulds front part crampons using vacuum casting system. Silicone mould will be used for casting of a certain number parts from commercially available materials. The work will be finished with technical and economic evaluation of production front part crampons with recommendations and the best economic analysis of alternatives.

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.

Silicone molds and their use
Rudolf, Jiří ; Zouhar, Jan (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis is focused on the design and production of a headphone holder. Thesis is divided into theorethical and practical part. The theoretical part is described Rapid Prototyping technology, precision casting with use of silicone molds and precision investment casting. The practical part is focused on the design of a headphone holder in CAD system Autodesk Inventor and following production via two different methods. The first way is 3D printing by Fused Deposition Modeling method and the second way is casting wax and plastic models using a silicone rubber mold. Conclusion of this thesis contains technical-economic evaluation and comparison of both manufacturing methods.
