Application of modern technologies for the production of the release mechanism of a car door
Hruška, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The Bachelor`s work concerns the production of door ulocking mechanism for a passanger car Renault Megane. From the viewpoint of function and the necessity to keep the exact dimensions of chosen parts were the data for the production obtained by digitalization of a real product. The digitalization was carried out by the contactless optical 3D scanner of GOM mbH company, specifically the developmental series ATOS II Triple Scan. The pin`s data were obtained from parametrical program Autodesk Inventor 2011. For the production of Master models the additive technology Rapid Prototyping, method Fused Deposition Modeling, was used. Master model of the handle was used for the production od solicon mould, that was used for casting of required number of handles from resin. The end of the work deals with a technical and economical assessment of the production. A part of the work is also a summary of the most used methods of Rapid Prototyping and Reversible Engineering.

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.

RP technology using FDM method and investment casting technology
Kosour, Vojtěch ; Krutiš, Vladimír (referee) ; Horáček, Milan (advisor)
An overview of the development of the Investment Casting market and Rapid Prototyping equipment is given in the introductory part of this diploma thesis. Basic methods of rapid prototyping and the FDM method are futher described in detail. The FDM method is consequently used in the practical part of this work for the preparation of the silicon mould. The largest part deals with the issue of the simulation of pouring process of wax into the silicon mould. A characteristics of the casting wax is made; the parametres, which are inserted into the simulation software ProCAST and the possibilities of their measurement are described. The process of the simulation of the mould filling and its validation with the real filling process are described in detail.

Possibilities of using modern methods in manufacturing of prototype castings
Šmíd, Jiří ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
The introduction part of the thesis focuses on the overview of rapid prototyping in foundry industry. Principles of the most important RP methods are described and the FDM method is analyzed in more detail. This method was used in the practical part for the production of wax patterns with silicone moulds. The wax patterns were used for the production of castings using the lost wax method. The result of this work is determination of dimensional changes during the whole process of casting manufacture from the drawing to the final casting.

Application of Rapid prototyping for production of historical models of assault force vehicles
Malý, Ondřej ; Sedlák, Josef (referee) ; Dvořáček, Jan (advisor)
The paper deals with the production and subsequent evaluation of produced historical trolleys Steyr K2670 models at a scale of 1:120. For manufacturing of the product was used rapid prototyping technology, which creates objects based on the virtual designs. In order to compare, the prototype model was built on different machines, using different methods of making bodies. Based on the final product was produced 3D printing silicone mould, into which was casted the modeller resin in the vacuum chamber. The conclusion is that for objects with very fine detail, it is suitable to choose a machine with high accuracy, working with thin layers of material. The prototype needs to be shaped before creating mould because silicone mould transmits most of the details, such as the texture of the surface layer structure.

Using of RP techniques and lost wax technology for medical castings
Pavelka, Tomáš ; Joch, Antonín (referee) ; Horáček, Milan (advisor)
The goal of the diploma thesis is to verify the possibilities of obtaining the casting of the femur component of the customized knee replacement using the technology of Rapid Prototyping and investment casting. To get the wax pattern it is used the method of fabrication the silicon rubber mould. Its optimalization from the wax pattern quality, economy of production and cooling speed aspects is important parameter at repeated production of the wax patterns.
