Mechanical design of 3D printing head for concrete mixtures
Slavíček, Jakub ; Němeček, Stanislav (referee) ; Paloušek, David (advisor)
This diploma thesis deals with a design and manufacture of an active print head used for 3D printing of concrete mixtures. The aim is to ensure functional parameters of the print head at a minimal mass. Extrusion of the material from the print head is ensured by a screw conveyor, shaping of the material is carry out by a rotatably mounted nozzle provided with trowels. The dimensioning of the main elements of the print head is based on the parameters measured during tests with the older version of the print head and on the FEM analysis. The print head was manufactured and is able to extrude concrete mixture with an admixture of aggregate (fraction 4–8 mm) at a rate of 0,5–2 m3•h-1. The weight of the print head is 16.4 kg, which is 30 percent less than an older print head weighed. The manufactured print head was tested during the printing of a real object and met all the required parameters. The print head is ready for implementation in a machine providing large-scale printing of parts in the construction industry.

Contract for health care under the Civil Code
Slavíček, Jakub ; Salač, Josef (advisor) ; Šustek, Petr (referee)
i Název diplomové práce v anglickém jazyce Contract for health care under the Civil Code Abstract This master thesis discusses a contract for health care under the Civil Code. A contract for health care was established as a new nominate contract type on the 1st of January 2014, as the Civil Code Act 89/2012 Sb. became effective. Considering the importance and wide use of the contract, it is staggering how the public knowledge about this topic is insufficiently low. The aim of this thesis is to generally introduce the topic and analyse its individual aspects. The thesis also draws attention to potential interpretation issues and legislative imperfections or ambiguities. The theoretical angle is suitably being supported by practical examples, which contribute to the overall understanding of the topic as well as make the explanation clearer. This paper gives an elementary explanation of relations between the Civil Code as a general act and special acts. To provide the best possible picture of the contract type, author likewise mentions a brief historical background and relevant elementary international law relations. Thereto the thesis includes an excursus to the English law, specifically to a patient's consent. Regarding the contract for health care under the Civil Code itself, the paper gives an...

Mechanical design of 3D printer head for manufacturing of concrete parts
Slavíček, Jakub ; Brandejs, Jan (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with a structural design of modular printer head used for 3D print of cementitious mixture. Printer head is designed for continuous printing of cementitous mixture with added crushed stone and accelerator. The main function of printer head is extrusion of the final mixture with established print parametres. In the thesis, the research was conducted into existing 3D concrete printing methods, possibilities of concrete transportation and material characteristics. The analysis is carried out in the second chapter, where the knowledge from the first chapter is evaluated and factors influencing the extrusion of concrete are defined. The design part of thesis specifies basic printing parametres and contains different alternatives of solution. The chosen conceptual solution is elaborated in detail and construction solution includes verifying calculations.
