Calibration of GOM ATOS optical coordinate measuring machines
Košťák, Ondřej ; Jankových, Róbert (referee) ; Harčarík, Matej (advisor)
This master’s thesis contains the basic division of 3D methods which are used for reconstruction of measured objects. Furthermore the types of structured light patterns used for 3D triangulation. It also contains a description of the construction and functions of GOM ATOS and TRITOP machines. Primarily the thesis deals with the calibration of these machines, the design of suitable materials standard of size and the internal calibration methodology used by ŠKODA AUTO a.s. The text also includes verification of the proposed calibration procedure in practice, proposal for determination of calibration uncertainties and recommendations for practice.

Mechanical properties of materials for 3D printing
Janiš, Adam ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This thesis focuses on the description of 3D printing technologies using the FDM method, which uses deposition of molten thermoplastics and their subsequent cooling and solidification layer by layer. This unique structure then shows a strong anisotropy of mechanical properties and, as a result, their testing and print settings are very important. Tensile testing of plastic materials, including indicators of mechanical properties, are described in this thesis according to ČSN EN ISO standard. The practical part presents the concept of a device capable of performing these tests. The block diagram indicates the functional elements and the connections among them. Tensile strength test is described together with results processing. Necessary product documentation is also included.
