System of large-scale 3D printing of products from bar structures
 Vašátko, Marek ; Němeček, Stanislav (referee) ; Škaroupka, David (advisor)
This thesis deals with the design of a system for the production of lattice spatial structures from polymer materials printed by a robotic arm. The aim of the thesis is to design a suitable manufacturing system in general and to experimentally verify the production of products on the current form of the system. Using compression tests to determine the load carrying capacity of the fabricated lattice structures and compare it with a computational model of the ideal geometry. In general, the parts of the manufacturing system were designed and experimental measurements of compression tests on fabricated specimen structures were carried out. The first results of compression tests of such fabricated structures for two cell topologies were obtained. The accuracy between the experiments and the computational model is comparable to the results in the current literature. Better results were obtained in the areas of repeatability of the obtained load values. The system is a combination of HW and SW solutions providing 3D printing of large-scale lattice structures for large volume parts and represents an incremental improvement of partial properties.
