Analysis of the mechanical properties of plastic materials for 3D printing
 Jelínek, Jan ; Bártková, Denisa (referee) ; Koutný, Daniel (advisor)
This work will solve the mechanical properties of materials used in the FDM technology.Thetensile and flexuralmechanical properties depending on theprintingparameterswillbetested. Fortestingare used three types of sampleswithdifferentrastersforeachof the tests. The first type of raster is characterized by a fundamentalparameter, whichisoffered by themanufacturer. The second type of raster is characterized by a high number of thin-fiber material and a higherconcentrationof air gaps. The third type of rasterischaracterized by minimalnumberof air gaps and a minimum number of thick-fibers in thecross-sectionalofsample. These typesofsamples will be tested on selected materials. The results of individual tests willbecomparedamongselectedmaterials and types of samples. The aim of this work is to show the dependence of mechanical properties on the type ofprintingstrategy.

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.
