Analysis of temperature profile of 3D printer hot bed and hot end by using CAE
Severa, Tomáš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master‘s thesis deals with 3D printing for non-commercial RepRap 3D printer type and materials used in printing. The outcome of this work is a brief introduction to 3D printing, the theory of heat transfer and analysis of the two most important parts of the printer hot bed and hot end. To analyze and optimize the temperature profile of the hot bed and hot end are used Computer Aided Engineering systems CAD and CAE, SolidWorks and SolidWorks Flow Simulation.

3D FDM printer Rebel II and parameters of print
Pištek, Patrik ; Zouhar, Jan (referee) ; Zemčík, Oskar (advisor)
This work deals with a RepRap 3D printer. The introductory chapter describes rebuilding, the reason of the rebuilding and basic components of a 3D printer. The following is a selection of lesser-used materials PETG and nylon. The individual chapters summarized reviews of experimental studies and the types of samples used in the testing of similar machines. Based on this information the author design size and shape of the sample for the second experiment, chosed relevant technological parameters and proposed plan of the experiments. Investigated parameters are temperature of the nozzle and printing speed. Experimental part of this work includes two experiments. In the first experiment, thin-walled objects by width of a single fiber were printed. The surface quality of the fibers was observed under a microscope. The second experiment evaluated the dimensional variations of the samples in dependence on the aforementioned parameters. Samples were scanned at the office 2D scanner and arithmetic mean of surface roughness Ra was measured by roughness meter on the side and top wall of the samples. The results and recommendations of the author are summarized in separate sections. The temperature and speed affected the quality of the surface of extruded fibers. The effect of temperature on the quality of the bond between the fibers has been significant. Print speed heavily influences the dimensional accuracy and deformation of geometric elements of the sample. The effect of temperature on dimensional accuracy was much less pronounced. In discussion part are expressed some ideas for future experiments. The conclusion summarizes all the gains of this work.
