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.

Design and Production of External Aquarium Filter Prototype
Svoboda, Richard ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This Thesis is about the design and production of an external aquarium filter prototype. My prototype uses the method of the method Fused deposit modeling. The filter model was designed in a 3D parametric software Solidworks and printed by 3D-Printer uPrint. The thesis describes how the issue of waterproofing printed parts is solved, and also how the appropriate thread (diametr 90 mm) is chosen for printing.

QFN Packages Soldering and Technology Procedures
Jakub, Miroslav ; Brno, Petr Martinec, HONEYWELL (referee) ; Starý, Jiří (advisor)
This master´s thesis deals with QFN packages soldering and technology procedures optimization. The aim of theoretical part is description of QFN packages, their assembly and reflow soldering on PCB in HONEYWELL. The aim of the practical part is to propose a method of measuring temperature and optimizing the thermal profiles of selected PCB with QFN packages by using convection (HONEYWELL) and infrared (BUT) reflow ovens. Comparison and evaluation of thermal profiles for 3 production PCBś with QFN packages using solder paste AIM NC257-2 were realised. The main part of master´s thesis are appearance evaluation of solder joints, preparing microsection and measuring intermetallic layers thickness by using the optical and the scanning electron microscopes, analysation and study of QFN defects created during soldering proces. These tests were performed with 2 production PCB´s. Optimization of SPI and soldering technology procedures where were analyzed QFN packages were processed on one type of PCB. Interesting part of this diplomma thesis is creating of the 3D heat transfer model of QFN package during the reflow soldering in SolidWorks.

Production Concept of Vacuum Mold for Plastic Forming
Tišnovský, Jakub ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
Vacuum plastic forming is method of termoplastic material treatment. This method uses physical and mechanical changes caused in materiál during his heating. Production of final product requires mould. The main advantage of this technology is fact, that manufacturing of mould is not so hard as manufacturing of mould for injection moulding, so mould is signficantly cheaper. Main purpose of this thesis is to propose production concept of this mould. Proposal was solved by SolidWorks and PowerMill software and manufacturing was realized on 3-axis CNC milling machine. Main result of this thesis is a summary of instructions which can be used in proposes of different moulds for vacuum plastic forming.

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.

Design of 3D model Jawa 50 engine cylinder and its possible realization in production
Dusbaba, Michal ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
This thesis deals with the 3D model design of the Jawa engine cylinder 50 produced by means of modern technologies with the use of CAD software. History of selected Jawa 50 motocycles was summarized in this thesis. In addition characteristics and analysis of used materials (additive and cast) were given to describe the Jawa 50 engine cylinder production. The parametric programme named SolidWorks was used for the Jawa engine cylinder 50 design. The principle of Rapid Prototyping additive technology was described and analysed as a part of this thesis as well as the detailed demonstration of one of these methods called Fused Deposition Modeling on a pilot model of the Jawa engine cylider. The thesis also elaborates on a pilot production of the real engine cylinder casting using technology of casting - namely the technology of precise casting with the use of meltable models. The thesis is concluded with discussing disputable steps undertaken in particular production phases.
