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 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.

The Design and the Possible Practical Application of a Cooking Pot Handle 3D Model
Bezděk, Adam ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The target of this bachelor thesis is designing and producing of a 3D model cooking pot handle with use of the modern 3D printing technologies. The virtual model of the cooking pot handle was produced with parametric program Autodesk Inventor and then printed by the Dimension uPrint 3D printer, which uses the Fused Deposition Modeling additive technology. The silicone mold was produced by using the printed master model. Then the model was molded from the two component plastic material into the silicone mold. Conclusion of this work contains technical-economic evaluation, where are both methods of producing the model compared.

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.

Prototype Part Design Using the Reverse Engineering Technology and Rapid Prototyping
Luňák, Václav ; Sámelová, Vendula (referee) ; Slaný, Martin (advisor)
This Bachelor thesis is dealing with the manufacturing process of a motorcycle turn signal part using the technologies of reverse engineering and rapid prototyping. The thesis contains a brief description of the available technological methods. The following chapters deal with designing the component and its preparation for casting. The component is manufactured using the FDM method. The quality check is performed by the ATOS 3D scanner, which compares the newly manufactured component to the original part. The next step is the preparation of a silicone mold, which is used to cast more parts. Finally, the cost-effectiveness of this method is compared to the method using metal molds.

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.

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.
