Application of modern technologies for the production of spare parts airsoft guns
Král, Ondřej ; Zemčík, Oskar (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis describes design and manufacture of airsoft spare parts. Selected spare parts were hammer and spring holder, which were designed in 3D parametric software Autodesk Inventor 2016. Chosen method to manufacture spare parts, was Fused Modeling Deposition, which is part of Rapid Prototyping technology. The device for producing parts was 3D printer uPrint. The manufacture of silicon mould was based on printed spring holder, which was used for parts manufacture, by casting plastic materiál. Thesis is completed with a technical-economical evaluation, in which it was found that the silicon mould casting is more profitable in the production of more parts.

Casted Formula Student Upright
Doležal, Tomáš ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
Bachelor thesis deals with a design of casted upright for Formula Student vehicle Dragon X. Casting method used for the purpose of this thesis was selected by review of relevant scientific literature. The upright was then structurally designed and strength calculations were made. Main criterion of the design is minimum compliance with meeting the required weight. Final design is compared with the design of the previous generation of vehicle.

Manufacture of cast Early Middle Age Viking Weapon parts
Brůža, František ; Mareček, Petr (referee) ; Záděra, Antonín (advisor)
The Bachelor’s project is concerned with the research and the following analysis of information and the period technologies needed for making a replica of the brass hilt of a 10th century sword. The project particularly focuses on the period casting technology. Next, the possibility of making a replica by a 3D scan and 3D print is discussed. The project also includes a comprehensive experiment consisting of casting parts of the hilt using the period technology. The functionality reproducing the hilt by 3D technology up to the printed model stage is also tested.

Application of Modern Technologies for Production of Front Part Fastening System Mountaineering Crampons
Samohýl, Lukáš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The aim this bachelor thesis is a production of prototype front part fastening system mountaineering crampons. In this work will be carried out the design and construction of a new prototype parts using the parametric application SolidWorks. For prototype production front part crampons will be used additive method Fused Deposition Modeling - uPrint 3D printer. Part of the work will be production of silicone moulds front part crampons using vacuum casting system. Silicone mould will be used for casting of a certain number parts from commercially available materials. The work will be finished with technical and economic evaluation of production front part crampons with recommendations and the best economic analysis of alternatives.

Manufacture of centrifugal Castings from iron and non-iron alloys
Žanda, Miroslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The thesis describes and characterizes the foundry method of centrifugal casting, which was established in the 16th century. Based on a literature study of centrifugal casting and centrifugal force, the principle of centrifugal casting is described. Centrifugal casting can be divided according to the position of the axis of rotation to horizontal and vertical or by the method of right centrifugal casting, semi-centrifugal casting, centrifugal casting, or Tekcast method. The most basic and most common centrifugal casting product is a pipe. The pipe production is progressing from material melting, pre-operation machine preparation, casting and solidification of the melt, to adjusting and finishing of the pipe. We can cast centrifugally a several of materials, especially steel, cast iron, copper, zinc, aluminum and titanium. Centrifugal casting can also cast multilayer castings.
