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.

Use of 3D printing in the Czech Republic
Kopecký, Miroslav ; Varhaník, Matúš (referee) ; Sedlák, Josef (advisor)
3D printing is a widely recognized and well established technique that enables the fabrication of complex structures with low production cost and easy scalability. In this study was conducted a comprehensive review of the applications of 3D printing in various industries in the Czech Republic. The first part of the research provides a summary of the different 3D printing techniques available, along with a comparison of relevant printing parameters and acquisition costs. The next part continues with description of the practical applications of the explained 3D printing methods in the Czech Republic industires. Namely, the applications in construction, automotive, education, and healthcare industries are discussed in more detail. The latter one is then brought into focus in the practical part of this work, where a medical aid is fabricated. Specifically the Fused Filament Fabrication (FFF) and Stereolithography (SLA) printing methods are used to fabricate a balance plates for lower limb proprioception training as a cost- effective alternative to commercially available product. Through a comparison of physical measurements, was found that the FFF method yielded more precise printouts. This research highlights the potential of 3D printing in delivering tailored medical aids, offering a promising avenue for future development.
