Implementation of 3D RepRap Printer
Sochor, Marek ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The aim of the bachelor thesis is build and verify the functionality of the 3D RepRap printer . The printer will be assembled from normally available parts and also 3D printed parts, becouse its main idea of the RepRap. After verifying the functionality of 3D RepRap printer We print identical part on two types of printers (RepRap 3D printer tand uPrint printer) and to evaluate the overall analysis (financially and physical). The work will be completed evaluation of usability and competitiveness assembled RepRap printer in practice and will be carried out, the technic-economic evaluation.

Innovation of the Rep Rap 3D Printer
Zítka, Lukáš ; Zemčík, Oskar (referee) ; Sedlák, Josef (advisor)
The present Master thesis is focused on innovation and verification of the functionality of a 3D RepRap. The theoretical part of the thesis characterizes individual additive technologies. The practical part is focused on the design of the technical modifications of the printer in order to achieve the quality of the printing, while the current 3D printer design is compared with the innovative solution. The practical part tests the setting of print parameters, various materials for 3D printing and necessary finishing operations. The thesis is completed

3D FDM printer with a replaceable print head
Čuma, Zdeněk ; Kupčák, Radim (referee) ; Zemčík, Oskar (advisor)
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.

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.

Design of dual hot-end for FDM 3D printer
Prouza, Tomáš ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
This master thesis is focused on a research in the field of 3D printing technology. During the research a particular technology, being regularly applied by the RepRap printers, is described. Mentioned technology is tested on a Rebel II printer model. The findings are applied to the dual 3D extruder design project. This dual 3D extruder is designed and made in two basic options, where the first option discovers the shortcomings and the second option is modified and tested. In the following step, assessment of applicability, functionality, as well as economic analysis of production of this dual 3D extruder is made.

Production of designed quadracopter using rapid prototyping
Melša, Jan ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
Design and manufacturing of a quadrocopter prototype using the Rapid Prototyping additive technology – the Fused Deposition Modeling method – is the goal of this Bachelor’s Thesis. The Thesis describes the process the prototype has to go through from the 3D computer model, through production settings down to the production itself. The individual prototype models have been created using the Creo Parametric software and they are adapted to the real components of a functional quadrocopter. The Thesis ends with a technical-economic assessment.

My 3D Printer
Mošner, Ladislav ; Klepárník, Petr (referee) ; Španěl, Michal (advisor)
This thesis deals with the topic of 3D printing. The primary aim was to build a real printer with a stiff construction minimizing clearance, which affects the accuracy and quality of printing. The design of the 3D printer and its parts was highly influenced by the RepRap project, especially by the Rostock printer using the delta kinematics and Fused Deposition Modeling. The printer electronics is based on the Arduino Mega 2560 platform running a modified Marlin firmware. It uses a newly designed extruder that should prevent a filament from melting in a guide tubule due to a large heatsink. The experiments carried out show that the accuracy of the printer is within +-0,1 mm.

Using 3D printing in HVAC
Malovaný, Ondřej ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
In the experimental part of this thesis there is an assessment of pressure bearing capacity of cylindrical nozzles printed using a 3D printer. In the theoretical part of this diploma thesis there are outlined the types of additive technologies focusing on the development of FDM printers, open designs and RepRap project. Descripti-on of the production process of 3D printing and application of additive technolo-gies in the field of HVAC. In the project part, the design of the forced ventilation of the Sports Hall is solved. The object is assessed in terms of heat losses and profits for priority rooms of functional units. Heat load coverage is carried out by air-conditioning equipment. In addition, a project is drawn up which contains all the text and drawings, including technical specifications and regulatory schemes.
