Manufacturing technology of a car copy by digitizing method
Eis, Jiří ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
This thesis, maked as diploma project at VUT Brno, summarize in teoretical part most used methods, technology of reverse engineering and rapid prototyping, including their using in practice. Experimental part discussed about aplication of this technologies on practical example. Tendency of thesis was creation of digitized model of a car by optical scanner ATOS and photogrammetry system TRITOP, including modifications and processing of get data, which will use to verification of model by FDM technology.

Adjustable Wrist Orthosis
Molinari, Petr ; Gajdoš, Petr (referee) ; Paloušek, David (advisor)
This bachelor‘s thesis is focused on construction of adjustable wrist orthosis using the method of Rapid Prototyping. The first part is devoted to the basic principle of Rapid Prototyping and description of the selected aditive technologies. The common part deals with an overview of upper limb orthotics, division of braces and presentation of some mass-produced models. In the section devoted the construction is described the whole process of designing orthosis.

Generic Obfuscation on the Bytecode Level
Kollát, Samuel ; Křoustek, Jakub (referee) ; Ďurfina, Lukáš (advisor)
This work contains definition of obfuscation and methods of obfuscation. It is followed by description of LLVM Project and its suitability for obfuscation on the bytecode level for purpose of targeting different architectures. The core of the work is formed by detailed design of obfuscation methods aiming towards their implementation in back-end of LLVM compiler. Closing section is dedicated to verification of implemented functionality on different architectures by automated testing.

Rotary table for 3D scanner
Suchý, Lukáš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master thesis deals with the 3D scanning. This thesis explain methods of reversal engineering with a special aim for technical disciplines. Also some examples are being given. Next part deals with the 3D scanning technology and focuses on separation of scanners to a different groups and associated technology. Basically the scanning methods are separable to destructive and non-destructive groups. An images are obtained by 3D scan, its problematics and z-axis acquisition follow in next part of the thesis. Afterwards some key parameters suitable for selection of scanning systems are selected. A scanner "David SLS2" and its basic parameters, manipulation, service and calibrating process is being described. Last part deals with function and construction of rotating table used together with the 3D scanner David SLS2.

The utilization of reverse engineering in computation of vehicle aerodynamics
Rozsíval, Jan ; Forman, Matěj (referee) ; Porteš, Petr (advisor)
The vehicle body was measured by using ATOS 3D scanner. Measured data from the ATOS 3D scanner were applied to make a 3D model of vehicle body and to make a 3D model of whole vehicle by using computer program Pro/ENGINEER. The model of vehicle was made with a view for future use of CAD model. Surface of the vehicle model was used for computation of vehicle aerodynamics – aerodynamic static pressure distribution by using CFD software Star-CCM+.

A car prototype manufacture using modern methods and CAD/CAM
Horák, Aleš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method. Verification of the results was performed on a vertical milling cantilever FV 25 CNC with control system Heidenhain iTNC 530 using a cutting strategies by PowerMILL CAM software. At the end of the resulting models edit as necessary.

Replica of a historical machine gun mount
Doležal, Jakub ; Suchý, Jan (referee) ; Maňas, Pavel (advisor)
This bachelor's thesis deals with the analysis and construction of the Královopolská gun mount replica, which were equipped in selected objects of Czechoslovak border fortifications before the World War II. This work is devoted to the analysis of the original documents for the gun mount, CAD model creation, 3D scanning and modification of scanned polygonal mesh of the heavy machine gun vz.24, which was selected as an example of machine guns mounted in the Královopolská gun mount. This is followed by a virtual compatibility check of the gun mount model with the machine gun model. The production model creation is introduced in next part, using technology with the lowest possible production costs. Complete drawing documentation for the replica production is also part of this bachelor thesis.

Production of castings using Rapid prototyping
Baránek, Martin ; Myška, Martin (referee) ; Bořil, Petr (advisor)
The work is focused on the production of a decorated stand casting using rapid prototyping and reverse engineering methods. The thesis first performs a literature search dealing with selected additive technologies usable for the production of foundry patterns or molds. Subsequently, the work describes the basics of 3D scanning technology. The experimental part of the thesis describes the production process of castings. The original was first digitized using a hand-held scanner, the obtained data were modified as needed and served as an input for 3D printing of permanent foundry patterns. Their production took place on a FDM 3D printer PRUSA MK3S and they were made of PLA material. The models were then formed into sand molds. The resulting castings were made of grey cast iron.
