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.

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.

Design of Stirling Engine Operating at Low Temperature Difference
Gavač, Adam ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
The aim of this study is to acquaint the reader with the Stirling engine, which is one of the possible alternatives to generally known combustion engine. The theoretical part has three major purposes: First is to describe thermodynamics of the Stirling cycle in the range that is essential for comprehension of the engine`s operating principle. Second is to mathematicaly derivate expression for the efficiency of the ideal Stirling cycle. Third is to discuss each of the essential parts of the device. Concepts acquired in the theoretical part were employed to design a digital model in the parametric modeler Autodesk Inventor. Parts were manufactured by a combination of typical and progressive technologies. Engine was assembled and tested afterwards.

Application of Fused Deposition Modelling Method to Production of Planetary Mechanism Model
Kudláčová, Barbora ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This thesis aims to deal with designing and construction of the planetary mechanisms mod-el with using the technology of Rapid Prototyping. Virtual model was designed by para-metric program SolidWorks 2013 and produced by 3D printer called Dimension uPrint, which uses Fused Deposition Modeling for the production. The thesis also includes the description of the planetary mechanism especially from theoretical, practical and also construction knowledge. The thesis contains the description of Fused Deposition Modeling too. The model of planetary mechanism is using as an educational tool especially for students of BUT Faculty of Mechanical Engineering in the subject Kinematics.

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.

Design of shell orthopedic insole fabricated by 3D printing
Chaloupka, Matyáš ; Koutecký, Tomáš (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the design of shell orthopedic insole fabricated by 3D printing. The background research is focused on matters of pes planus and on the methods of Rapid Prototyping including most commonly used materials. The structural design is focused on designing a material pattern for this medical instrument and consequently modeling sandwich structure by combining two materials, plastic and softened plastic, which is then made using Rapid Prototyping on Fused Deposition Modeling 3D printer. Rhinoceros© was used for the purpose of making a shell orthopedic insole, especially it’s algorithmic editor tightly integrated with Rhino’s 3D modeling tools, Grasshopper®. Final part was made with sandwich structure by combining PLA plastic and Flex material using Rapid Prototyping.
