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.

3D Printer
Ctibor, Jiří ; Knobloch, Jan (referee) ; Cipín, Radoslav (advisor)
Master thesis deals with topic about 3D printers, concretely making hardware of control and power electronic for FDM 3D printer. The work could offer an overview about basic 3D printing technologies after reading. More information could be read about FDM technology, which is used in our printer, also with description of all important components. The furthest is discussed about electronic drives. If reader is interested in this topic, part of this thesis is schematic design of control electronics, which can be used to build own boards. Design of printed circuit boards is not present in attachment and can be obtained by contacting the author. For own control is used one of the open source control software. Mechanical problems and also mechanical design is done in parallel thesis by other student of Faculty of mechanical engineering.

Effect of the diameter of the nozzle on the 3D printer print quality
Kutil, Jaroslav ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
The matter of this thesis is to find the influence of the diameter of the nozzle on the 3D printer´s print quality. The first part briefly characterizes the Rapid Prototyping technology and describes the RepRap project. The second part describes the construction of the experimental FMD 3D printer. The following section deals with technical printing parametres and their influence on the printed product. The experimental part of the thesis is focused on the impact of the discharge nozzle diameter on the mechanical properties, surface quality and shape accuracy of the final product and on the following recommendations of operational parametres.

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.

Production and aplication of 3D FDM deltabot printer
Knapil, Josef ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
The thesis describes design and aplication of 3D FDM printer type of delta. The first part describes methods of rapid prototyping. The second part describes 3D printers type of delta. The third part deals with construction and calibration of delta printer. In the fourth part are made suitable modifications to the design of the printer, to improve the quality of printing, which is then applied on a sample product. The final section is devoted to technical and economic evaluation.

3D FDM printer reprap and parameters of print
Kratochvíl, Tomáš ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This master thesis summarizes the current knowledge about non-commercial 3D printing FDM technology. The goal of this thesis is to demonstrate the gained knowledge by building a 3D printer which can partially replicate itself, and to evaluate its technological parameters. The experimental part of this work is focused on the impact of the changes in technological parameters of printing on mechanical properties of printed parts.

Surface treatment of ABS parts after FDM 3D print
Světlík, David ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
This master thesis deals with the surface treatment of parts made of plastic produced using FDM technology and design of technological device for surface treatment. The thesis describes FDM principles, according to performed experiments in a technological device there are suggested technological conditions for the surface treatment of parts made of ABS plastic. In the end of the thesis, there are calculated costs of the technological device and its operating costs, also mechanical properties, surface roughness and other specifications from before and after the treatment are compared.
