This diploma thesis deals with matte coatings for optical 3D scanning. The aim of this thesis is to find a method of spraying the mixture of TiO2 and ethanol that would provide layer thickness beyond the measurable range of the 3D scanner. A spray gun allowing deposition of atomized mixture was design. The coatings created by this gun and by airbrush gun, which is commonly used for this purpose, were compared. The matting effect, thickness and the influence of used TiO2 particles were investigated in the coatings. The paper shows method of applying coatings that ensure sufficient matting of the surface for scanning purposes, and simultaneously have thicknesses that should not affect scanning results.

Rentgenová počítačová mikrotomografie (CT) je metoda pro trojrozměrné (3D) zobrazování vnitřní struktury objektů. Laboratoř rentgenové počítačové mikro a nanotomografie na CEITEC VUT (Středoevropský technologický institut, Vysoké učení technické v Brně) se zaměřuje zejména na nedestruktivní analýzu v průmyslovém odvětví. Ukázalo se ale, že tato metoda nachází široké uplatnění i v dalších vědeckých oblastech včetně vývojové biologie. Tato práce poskytuje propojení mezi materiálovými a živými vědami. Kompletní proces vedoucí k vytvoření 3D modelu různých anatomických struktur je detailně popsán. Tento postup zahrnuje kontrastování vzorků, samotné CT měření a analýzu dat. Právě zpracování dat je mnohdy považováno za nejdůležitější část v rentgenové počítačové tomografii a proto je této oblasti věnována v práci největší část. Úpravou měřicích parametrů byl dále optimalizován CT přístroj GE v|tome|x L 240 za účelem umožnění automatické segmentace. Navíc je diskutována možnost měření na synchrotronu za účelem zvýšení prostorového rozlišení a diferenciálního kontrastu. Předpokládá se, že v blízké budoucnosti získají průmyslové CT přístroje podobné zobrazovací vlastnosti, a to jak díky nedávnému vývoji v oblasti hardwaru, tak v oblasti zpracování dat.

This diploma thesis deals with the study of 3D printing based on the FDM method. This method focuses on the possibility of using two extruders it means that the composite parts can be printed. This diploma thesis describes the available variants of composite printing currently on the market. Based on the gained knowledge and the availability of 3D printers and software, individual variants of composite parts were printed. A tensile test was performed on these samples to determine the strength characteristics. Additionally, compatibility and adhesion of two selected materials were tested. Based on the testing is made an evaluation of the achieved results, effectiveness and feasibility.

The representation of 3D polygonal model on several levels of available detail is a problem inherent in the process of rendering a scene. Highly-detailed models, if placed far from the camera, suffer from spatial aliasing that results from inadequate sampling of their surface, and require disproportionately large amount of time to render. Low-detailed models on the other hand reduce the visual quality of the scene when placed too near to the camera. This report delves in both the theory and the practical techniques used for solving these problems. It describes various published solutions and the principles behind them, and presents a design and an implementation of selected techniques for the GPUEngine library.

This thesis deals with the creation of a parametric 3D city model based on available spatial data.. The content is divided into two parts. The theoretical part describes the current state of 3D modeling and the second part describes the process of creating the final model and its conversion to CityGML.

The target of this work is the development of a monitoring system for 3D printing by the Fused Deposition Modeling method, which will be able to identify printing error conditions. During the solving process the needed error conditions were identified. Then, an algorithm was programmed to identify the error condition using the criterion. The resulting Monitoring Hardware was implemented in the printer and experimentally verified. A system has been developed that can identify error conditions with an accuracy of 94.7%. The main benefit of this work is the automatic identification of error conditions that stop printing if necessary. This leads to a reduction in scrap and cost savings. In the future, the software could automatically adjust the print parameters when identifying an error condition. This would prevent or completely eliminate the error condition without user intervention.

This study has been as a diploma project at BUT. Theoretical part describes the most used methods in Reverse engineering and Rapid Prototyping. Each method describes its characteristics, usability and pros and cons in general. Practical part of this study deals with application of these methods. Goal of this work has been to obtain a digital model of a winker from Škoda 1000 car using optical scanner ATOS, making a new master model in CATIA software, analyzing its dimensions compared to the scanned model and choosing a suitable manufacturing technology with emphasis on functional properties of this component.
