3D print of composite materials
Kašpárková, Kristýna ; Zemčík, Oskar (referee) ; Zouhar, Jan (advisor)
The submitted thesis deals with a study of composite materials and processing them using 3D printing technology. The experimental part of this thesis is focused on the production of test samples with the use of additive technology Fused Deposition Modeling and Continuous Filament Fabrication. The composite samples made of common onyx material, individually reinforced with continuous carbon fiber filaments, kevlar, or fiberglass, were made with Marforged Mark Two 3D printer. The other samples made of PETG PM and PETG CFjet materials were made with Original Prusa i3 MK2S 3D printer. For technological evaluation, a tensile test was performed on samples, following the norm EN ISO 527-2:2012. Based on results obtained from tensile testing, the properties of materials strength and usability are verified and compared. In this work, the production process is proposed, and technical-economic evaluation is made. In conclusion, achieved results and overall benefits of this work are summarised.

Use of 3D printing in the production of functional prototypes for automotive
Mikulášek, Marek ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This thesis deals with the 3D printing of composite materials. The constant development of this technology has enabled the application of this method for the production of prototypes, but also functional components. The theoretical part deals with the study of composite materials and the principle of production using additive technology. In the practical part, an analysis of the suitability of part processing using the 3D printing method is performed on a specific component and than applicated to the assembly hall located in ŠKODA AUTO a.s.

Analysis of mechanical properties of composite materials printed by additive 3D printing technology
Mudrák, Michal ; Joska, Zdeněk (referee) ; Sedlák, Josef (advisor)
This thesis deals with the analysis of mechanical properties of composite materials used for 3D printing by Markforged company. The theoretical part is focused on the characterization of composite materials and analysis of mechanical tests. The experimental part deals with the production of test specimens for specific mechanical tests (tensile test, Shore D hardness test and bending test). The test sapples with Onyx base material are individually reinforced with carbon and high-temperature glass fibers (HSHT). There are statistically evaluated selected parameters for individual mechanical tests (tensile strength, elongation, modulus of elasticity, Shore D hardness, bending stress and bending deformation). The thesisis completed by comparing selected parameters of composite materials with overall recommendations for users.
