Otočný stolek k 3D skeneru / Rotary table for 3D scannerSuchý, Lukáš January 2020 (has links)
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.

Optimalizace konstrukce bezpilotního prostředku vyráběného technologií Fused Deposition Modelling (FDM) / Structural optimization of 3D-printed Unmanned Aerial VehicleSladký, Martin January 2021 (has links)
This master thesis deals with the design of the internal wing structure of 3D printed flying wing VUT 714. As a part of this work was performed a load calculation, static strenght test, comparative FEM analysis and subsequently topology optimization was performed. The outcome of this master thesis is a rational design of the wing internal structure based on the load calculation and knowledge of effect of this load on the structure.

3D FDM tiskárna s výměnnou tiskovou hlavou / 3D FDM printer with a replaceable print headČuma, Zdeněk January 2021 (has links)
The aim of the work is to design and manufacture a mechanism for setting up and clamping the replaceable head of a 3D FDM printer. The first part of the thesis deals with 3D printing in general, the second part describes the FDM method. Part three is devoted to the selection and construction of a suitable 3D printer, the fourth part to the actual design of the head attachment. In the fifth part, a technical and economic evaluation is carried out.

Lepení FDM 3D tištěných dílů z PLA / Gluing of FDM 3d printed parts from PLAŠlimar, Filip January 2021 (has links)
The thesis deals with the theory of 3D printing, materials for printing and bonding. It focuses on FDM printing and PLA material. It also compares gluing with other methods and deals with the distribution of adhesives, the gluing procedure and tests of glued joints. The work, based on literature studies, proposes an experiment to evaluate selected adhesives. The practical part contains a description, results and evaluation of the experiment. The evaluation of adhesives is based on tensile and shear strength.

Analýza mechanických vlastností kompozitních materiálů vytisknutých aditivní technologií 3D tisku / Analysis of mechanical properties of composite materials printed by additive 3D printing technologyMudrák, Michal January 2021 (has links)
This thesis deals with the analysis of mechanical properties of composite materials used for 3D printing by Markforged company. The theoretical part is focused on the characterization of composite materials and analysis of mechanical tests. The experimental part deals with the production of test specimens for specific mechanical tests (tensile test, Shore D hardness test and bending test). The test sapples with Onyx base material are individually reinforced with carbon and high-temperature glass fibers (HSHT). There are statistically evaluated selected parameters for individual mechanical tests (tensile strength, elongation, modulus of elasticity, Shore D hardness, bending stress and bending deformation). The thesisis completed by comparing selected parameters of composite materials with overall recommendations for users.

Analýza mechanických vlastností plastových vzorků zhotovených technologií 3D tisku / Analysis of mechanical properties of plastic samples produced by 3D printing technologyJiroušek, Jan January 2021 (has links)
The master's thesis deals with the determination of mechanical properties of materials used for 3D printing (PLA, PETG, ABS, ASA). The theoretical part contains characteristics of polymer materials and describes testing of mechanical properties and additive technologies. In the experimental part, the standardized samples produced by the technology Fused Filament Fabrication were analysed using mechanical tests (tensile test and hardness test). Some of the examples were exposed to the selected factors of degradation. Selected parameters from mechanical testing (tensile strength, modulus of elasticity in tension, elongation and Shore hardness) were statistically processed. The conclusion of the thesis evaluates the impact of the factors of degradation on particular materials and compares them subsequently.

Analýza teplotního profilu hot bed a hot end u 3D tiskárny pomocí CAE / Analysis of temperature profile of 3D printer hot bed and hot end by using CAESevera, Tomáš January 2014 (has links)
This master‘s thesis deals with 3D printing for non-commercial RepRap 3D printer type and materials used in printing. The outcome of this work is a brief introduction to 3D printing, the theory of heat transfer and analysis of the two most important parts of the printer hot bed and hot end. To analyze and optimize the temperature profile of the hot bed and hot end are used Computer Aided Engineering systems CAD and CAE, SolidWorks and SolidWorks Flow Simulation.

Reliéfy / ReliefsHorčicová, Monika Unknown Date (has links)
This master´s thesis consists of three relief objects composed from femur bones. The first relief object is geodetic structure applied to the shape of a sphere. The following two are deformed by softening the material from which they are cast. The second relief object also works with geometry (a square at the base) and systematic folding bones according to a clear order. The third relief can directly interfere with the viewer - the individual femurs contain every two magnets and therefore can move freely with them after the metal plate.

Kroj / The Folk CostumesŽupková, Ilona Unknown Date (has links)
The outcome of my thesis is airy relief in the form of a spreaded Kyjov´s women's folk costumes. It is made up of embroidery and lace, which gets their original lightness without underlying substance.The white color, I have used, strenghts this feeling. All parts are printed by the ABS plastic. I follow the transformation of hand-made embroidery on the machine-made one with this. 3D printing is another entirely fictitious step for me. Just as the embroidery machine adjusts stitches according to their outline, as well as 3D printer has its own structure of applying material.

Povrchové změny v závislosti na parametrech FDM tisku / Surface changes based on FDM printing parametersČada, Jiří January 2016 (has links)
This thesis deals with a construction of modified RepRap 3D printer Rebel II which operates with Fused Deposition Modeling technology and selection of suitable criterion for printing. It mainly focuses on the temperature of the material being printed and speed of printing for three selected materials. Materials were selected based on availability in the market and their application. An experiment, focusing on surface changes of products as well as on the look of a fibre after passing through a nozzle, was performed.
