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.

Surface finishing of plastic parts
Ševčík, Igor ; Škaroupka, David (referee) ; Paloušek, David (advisor)
The purpose of this bachelor’s thesis is processing of theme surface finishing of plastic parts, specifically products of 3D printing made of Acrylonitrile butadiene styrene (ABS), and consequent experimental execution of chosen methods. The thesis includes analysis of current knowledge, description of various procedures and possibilities of surface properties modification. The aim of treatment is to allow further processing of plastic objects, such as metal coating. Experiment accomplish-ments are listed and the effect of surface treatment is evaluated afterwards.

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.

Assembling and Functional Verification of a Home 3D Printer
Tesař, Jaroslav ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
This thesis was created as a bachelor project in the Faculty of Mechanical Engineering at VUT in Brno. In the theoretical part, the additive technology Rapid Prototyping is introduced together with the most common methods, followed by the assessment of advantages and disadvantages of the new technology and its possible uses in various fields of human activity. In the experimental part of the diploma thesis was assembled and the printing parameters were set. Consequently the comparison models were printed on the 3D home printer and on professional printer Dimension uPrint. The accuracy of the printers is compared. The thesis concludes with the analysis of technical and economical parameters.

Simulation of Impact The Heated Bed on Printet Model in 3D Printer
Sodomka, Petr ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This diploma thesis solves the 3D printing problematics for non-commercial printers. Firstly possibilities of its using, heat diffusion and printing materials are described. Next part of thesis is focused on heating pads and printing nozzles for which 3D models in SolidWorks software are created. The temperature analyzes are tested with these models and then comparing of results is done. Working models for SolidWorks Plastics and SolidWorks Simulation software is created in following part. Thanks to this software tools printing model is simulated and deformation creating in printing process is observed. The most suitable solutions are chosen from gained solutions.

The Wheel of Death
Horčicová, Monika ; Chamonikolasová, Kaliopi (referee) ; Gabriel, Michal (advisor)
Bachelor thesis titled Wheel of death- Wheel of life cycle of life displays, which are inherently death. Object is part of the composition of the human skeleton in a circle, the imaginary ktrerý moves. The lower part of the wheel bends under its own gravity. The circle is a symbol of life and its cycle. The bones are a symbol of death.

Production of glovebox handle on FDM 3D printer
Šuranský, David ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
The bachelor thesis analyzes car interior handle production, whose design was slightly modified compared to the original part. It consists of few design drafts, selection of the most suitable one, modification for 3D printing purposes and the part production of ABS material on a FDM printer. Post-processing operations and technical as well as economical conclusions are mentioned at the end of the thesis.

Production of interior car handle prototype on 3D FDM printer
Kaššák, Marek ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This bachelor this processes the issue of manufacturing of a prototype of handle for the car interior using method fused deposition modeling method. First part of this is dedicated to a brief overwiev of prototype manufacturing using rapid prototyping technology , with FDM 3D printing and materials used by FDM method. Second part is dedicated to design of 3D model using AutoDesk Inventor 2014 software, prototype manufacturing itself, evaluating of construction technologicality and technological-economic evaluation of manufacturing costs.
