3	Konstrukce tiskové hlavy pro 3D tisk betonových směsí / Mechanical design of 3D printing head for concrete mixtures Slavíček, Jakub January 2020 (has links) 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.
4	Digitální zprovoznění robotizovaného výrobního systému pro 3D tisk / Digital commissioning of a robotic production system for 3D print Beránek, Ondřej January 2021 (has links) The master thesis describes the design and digital commissioning of a robotic production system for 3D concrete printing. The theoretical part of the thesis includes an analysis of the current state of knowledge in the field of 3D printing in industrial automation. It also includes a detailed system analysis of the problem, in which the requirements and elements of the production system are specified. In the applied part of the thesis, a 3D model of the workplace was created and a simulation of the entire production process and digital commissioning of the system were performed using the ABB RobotStudio software. The output of the of the application part of the thesis is the design is the design of the workplace with a debugged control program ready for use in real operation.
