Modelování prostorových struktur zhotovených metodou 3D tisku

Abstract

This bachelor thesis deals with the design and modelling of 3D spatial structures in terms of their mechanical properties, which vary depending on the geometrical parameters of the designed array. The aim of the thesis is to test the models created from these structures and determine their stiffness and also the maximum load they can carry. At the same time, the work includes the design of a computational model to complement the experimental testing. The introductory part discusses the applications and possibilities of these spatial structures and also presents the most known additive manufacturing technologies that allow to produce these structures. Finally, the most used materials for additive manufacturing are also mentioned. This is followed by a brief description of the testing methodology and then the testing of the selected designed structures. That is, the determination of stiffness and load capacity. Another part of the work is the computer modelling and analysis of these structures using FEM. Finally, an evaluation of the findings is presented. The work builds on the ongoing research on planar structures and extends it to spatial structures. The results can be used for the design of biomedical devices.
