Modification of 3D milling machine to 3D printer
Taska, Abraham ; Blecha, Radim (referee) ; Bradáč, František (advisor)
This work deals with the possibility of reconstruction of 3D milling machine into 3D printer. The first part is devoted to the search of possible printing heads for the use in the milling machine. This section also describes the most widely used 3D printing technology. Another part addresses proposal of connection of printing head into milling machine. The last section describes the control options of 3D printers and printing head.

Production of gears model on FDM printer
Frátrik, Michal ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis deals with an issue of 3D printing of gears. In the first part are concisely summarized processes of 3D printing, selected types of Rapid Prototyping considering the FDM and properties of materials used in this method. The second part deals with a suggestion of gears model based on the gearbox of the kitchen blender. Gearbox was designed in 3D modeling program Autocad inventor 2013 and printed on the Reprap printer Sinuhed. There is techno-economic appreciation of production of the model in conclusion.

Production of working replacement part on FDM printer
Frélich, Tomáš ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This bachelor's thesis is looking into the production of a part of a cover for ignitron of motorcycle Honda CR500R. In consideration of the required function and the attributes of the desired part an aditive technology called Rapid Prototyping (hereinafter referred to as „RP“) – method FDM (Fused Deposition Modeling) was chosen. The first part of this thesis defines summary of methods RP and materials usable for these operations. The second part is focused around a design for the 3D model in a program called Autodesk Inventor 2013, the production itself, evaluation of the technology level of the construction and a techno-economic evaluation of the costs.

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.

Realization of the plastic holder of the car navigation
Pavlík, Ondřej ; Nohál, Libor (referee) ; Paloušek, David (advisor)
The goal of this bachelor´s thesis is suggestion and manufacture of the plastic holder of the car navigation. The literature retrieval part contains gathering of information about external holders of the car navigations and description of prototype manufacturing method. The construction part is an accompanying report of suggestion and manufacturing of the car holder. 3D CAD Model is created in parametric modeller via Autodesk Inventor Professional 2010. The holder is then made via Rapid Prototyping FDM technology.

Technical aspects of the use of 3D printing in the education at elementary school
CVRČEK, Tomáš
This thesis in the beginning deals with the history of 3D printing and its development. For better understanding the nature of 3D printing are the significant technologies that includes. Professional part includes work with the printer MakerBot Replicator 2X. Mechanical parts of the device are analyzed together with the operating software MakerBot DesktopThe following chapter is dealing with the limits and restrictions when it is printed on said 3D printer, except that describes important aspects when working on the printer. For the creation of electronic models are suggested appropriate programs for use in elementary school. A significant milestone is forming the problems of 3D printing, which can serve as a guide for the elimination of print quality problems, malfunctioning of 3D printers and others. Interesting models are designed for teaching physics and working activities that the students facilitate understanding of the substance of the response and act as activating element within lesson. It was created a list of important sites where you can find models suitable not only for teaching in elementary schools, but also for other purposes. The last chapter deals with the economic aspect of 3D printing.
