Determination of Material Properties of Specimens Produced by Metallic 3D Printing
Zakl, Alexandr ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This bachelor's thesis deals with mechanical properties and current status of 3D printing of metal parts, especially by DMLS/SLM method. Research part is dedicated to various technologies and suppliers in the field of 3D printing with emphasis on printing metal methods. Main purpose of this thesis is to connect the worlds of 3D printing and 3D optical measuring of deformation, so the part of research segment is dedicated to optical measuring and leading innovative company GOM. One of the leading product of this company is ARAMIS and in the context of this thesis it was present during the experiment as a instrument for measuring and inspecting material characteristics, and is present in research part where is mentioned a principle on which this device is working (digital image correlation) as is the device itsself. In the experimental part of this thesis, samples were printed on DMLS printer from company XactMetal, which were then submitted to a tensile test. Measurement was done using DIC based device ARAMIS and inspected for basic material properties in same named program.

Analysis of Influence of Manufacturing Technology on Utility Properties of a Reducing Valve Part
Novotný, Michal ; Sigmund, Marian (referee) ; Řiháček, Jan (advisor)
The present work is focused on the comparison of the currently used technology for the production of reducing resistors, i.e. electroerosive machining in combination with soldering on one side and the use of a suitable additive technology on the other hand. In addition to the purely technological aspects, such as the individual production processes or their preparation, economic aspects are also compared, supplemented by an assessment of the delivery times of the finished parts. The analysis is carried out The environmental impact of both production approaches is also analysed. The individual comparisons form the basis for to assess whether the replacement of the conventional manufacturing approach by additive manufacturing is advantageous in this case. The results of this assessment can then be used for future applications of the considered additive manufacturing approaches for similar components.

Use of Additive Technology for the Production Concept of Turbocharger Components
Robl, Jan ; Ňuksa, Petr (referee) ; Sedlák, Josef (advisor)
The thesis deals with possible use of additive technology in heat-resistant aplications. The rapid improvement of additive technology in recent years has brought more advanced materials such as nickel based superalloys, opening new oportunities for the use of this additive technology. First part of the thesis is dedicated to nickel based superalloys processing, precision casting and metal additive manufacturing. Other part analysed the results of mechanical properties and textures of the surface followed by a comprehensive assessment of DMLS technology. Part of the thesis is also the analysis of fracture surfaces on transmission and electron microscopy. Based on acquired nowledge, the conclusion is made about the possible use of DMLS in the future of heat-resistant applications.
