Multifunctional modular FDM 3D printer
Indra, Zdeněk ; Vyroubal, Petr (referee) ; Jaššo, Kamil (advisor)
This work deals with problems of 3D printers, their types according to function principle and their design. In addition to print materials, FDM printers chapter includes the types of motion systems available for FDM 3D printing, and the possibility of converting 3D printers to other CNC devices is discussed. This theory is then evaluated and the most suitable parts are used to build modular CNC machine wich is then tested in configuration of FDM 3D printer.

Stereolithographic printer for producing a cell culture device
Gricová, Monika ; Vacula, Daniel (referee) ; Dostál, Zbyněk (advisor)
Stereolithography printing is one of the most popular 3D printing technologies. This printers use a UV light source for photopolymer curing and can be used for a wide range of applications with high precision and excellent print quality. Commercially available printers do not allow the modifications of the optical and mechanical parameters of the instrument. For this reason, a DLP printer has been designed to allow the optical system modifications and thus changing the printing field and resolution. Another advantage is the possibility to modify already designed mechanical parts. The DLP printer has been designed and tested. The recommended printer parameters settings are listed, which are based on the performed experiments.

Delta type of 3D printer
Němec, Radek ; Jaššo, Kamil (referee) ; Vyroubal, Petr (advisor)
This master thesis is about design and construction of FDM delta 3D printer which consists of 32-bit electronics, magnetics printer head and other necessary peripheries. Opening chapters of this thesis are about theory of 3D printing and its methods with description of FDM 3D printers and summarization of FDM plastic materials used for 3D printing. The next part is about used electronics and problematic of heat transfer. The main part of this thesis describes design and construction of 3D printer and its necessary peripheries, which includes creation of its 3D model and application for 32bit controller. 3D model of delta 3D printer and its heating components was created in CAD software SolidWorks. The last part includes description of commissioning and calibration of delta 3D printer with summarization of economic aspects of its creation.

Universal Cloud-Based 3D Print Slicer
Vejčík, Jakub ; Zbořil, František (referee) ; Kočí, Radek (advisor)
This bachelor thesis deals with the proposal and implementation of a cloud tool for preparation 3D models for 3D printing. 3D printing become a part of our lives and it is getting into schools, where it combines the digital world with the physical world. Nowadays schools have not sufficient computational power to handle demanding 3D models for 3D printing. This ascertainment has led me to create a cloud tool, because cloud provides sufficient computational power and it can be shared beetween multiple users at the same time. The cloud tool solves the problem of insufficient power to translate 3D models to G-code, which understands 3D printer. Solution is done by letting the demanding computing logic on the cloud and user just edit model according to his ideas in the web interface of cloud tool.

Robust wheeled robotic chassis
Jirges, Radek ; Chalupa, Jan (referee) ; Bastl, Michal (advisor)
This thesis deals with the issue of the proposal of mobile wheeled robotic chassis. In the introductory theoretical part gives an overview of the division of mobile chassis inclu-ding representatives of each group. In the begining of the practical part describes se-lection of suitable components for the chassis from drivetrain to controlling electronics. Constructional part of this thesis at first deal with selection of suitable material for each part of chassis and than follows construction of these components including decsription of used constructional solutions for each issue. Result of this thesis is robust wheeled chassis fitted with drivetrain and basic electronics.

Mechanical design of plastic parts crusher
Šebesta, Karel ; Brandejs, Jan (referee) ; Paloušek, David (advisor)
The thesis focuses on the construction of shredder of plastic components produced by 3D printers. The aim of the thesis is to design a shredder whose output components, the so-called flakes, could be used to produce recycled filament. The first part of the thesis covers an analysis of technology of shredding. Furthermore, the properties of shredded material and the requirements for the quality of output granules are determined. Based on the research, the parameters for the efficient shredder are defined. In accordance with these parameters, several variants are created, from which the final design of the two-stage shredder is selected and constructed.
