Hájíček, Marek ; Kovařovic, Karel (advisor) ; Kramperová, Veronika (referee)
Title: The use of the new technology when creating didactic aids for blinds and purblinds Compiled by: Marek Hájíček Supervisor: PaedDr. Karel Kovařovic Objectives: The aim of the study is to verify perceptibility of tactile 3D model by visually impaired and verify usefulness in swimming lessons for visually impaired Methods: Perceptibility assessment of 3D models based on the personal hisotory and test of basic knowledge of human anatomical topography and gymnastic terminology using special 3D models and painterly human model for the visually impaired probands. Results: Based on the test results and comparison of results between the different categories, I found that the selected size and parameters of special 3D models is sufficient, and that visually impaired people to these haptic devices respond very well. According to the results I can say that skills required for the needs of further research are sufficient. Keywords: Swimming lessons, visually impaired, swimming equipment, 3D printer, 3D model

Virtual prototype of mechatronic system
Dinga, Milan ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with modeling of delta 3D printer virtual prototype and its co-simulation using software ADAMS and MATLAB/SIMULINK. The first part consists of virtual model creation and its kinematic analysis. Then a model of electric motors is created. The final part consists of co-simulation and control design.

CNC router for PCB
Gerják, Rastislav ; Vaculík, Sebastian (referee) ; Vyroubal, Petr (advisor)
In mechanical industry, both additive and subtractive manufacturing methods are controlled by instructions in G-code, making it possible to utilize both technologies in one modular device. Main objective is to design, construct, and calibrate multipurpose machine based on RepRap 3D printer, which will be able to use attached spindle to precisely mill light materials. Particular emphasis is given to ability to carve a pattern and drill holes in plated substrate in order to create functional PCB by incision.

Experimental 3D printer for the selective laser sintering of polymers
Kroutil, Tomáš ; Čížek, Petr (referee) ; Paloušek, David (advisor)
The diploma thesis deals with design and realization of experimental 3D printer for selective laser sintering of plastic powders. The output of the work is a device that can create the main process conditions for laser sintering. A diode laser is used in the device, which allows aluminum composite powders to be processed. The printer allows you to heat up the applied layer of powder and set-up space. The research section focuses on similar equipment, process parameters, laser technology and control system. The design section contains solution variants and a description of the chosen solution.

Effect of air temperature on FDM 3D printing
Hrdlička, Martin ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The thesis deals with 3D printing by the FDM and ambient temperature on print quality. The thesis describes the principle of printing by the FDM method and the occurrence of errors caused by the influence of ambient temperature. The aim of the thesis is to design a heated chamber for RepRap Prusa i3 printer, its construction and subsequent testing of ambient temperature influence on print quality. To test the occurrence of the described errors, specific tests and materials are selected in the work. The result of this work is the recommended ambient temperature in the heated chamber for improved FDM printing.

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.
