Abstract:

The thesis deals with the design of a transtibial prosthesis by additive manufacturing technology. Based on walking biomechanics and the current situation of knowledge a prosthetic foot has been designed for a patient with low level of physical activity. Furthermore, the thesis describes the design of an individual socket for the patient. The socket has been designed by reverse engineer procedure based on the three-dimensional geometry of patient´s stump obtained by 3D scanning. Testing samples of the foot and the socket have been made for the check of functionality of both the devices and then subjected to mechanical tests in accordance to the methodology regulation ISO 10328. Finally, the thesis depicts the FDM technology used for the production of functional samples of the designed devices; assembly of modular transtibial prosthesis and its testing by the patient.

The first part of the diploma thesis is focused on the analysis and evaluation of the current production of sipes by two SLM devices PXL and M2 Cusing, produced by Phenix Systems and Concept Laser companies. The samples of both machines went through the same manufacturing process and the same process of measurement and evaluation, in order to carry out comparison between individual machines. Geometric accuracy, surface roughness, mechanical properties, and material structure of the samples have been compared. For the sipes it was necessary to create a digital evaluation methodology of geometry. In the second part of the thesis, process parameters are selected on the basis of research and further their influence on surface roughness of manufactured sipes is analyzed.

Abstract:

Metal additive technology allows to create objects with complex shape that are very difficult to produce by conventional technologies. An example of such component is a porous structure which is composed of periodical truss cells. This diploma thesis deals with the prediction of the mechanical properties of very small lattice structures made of additive manufacturing technology Selective Laser Melting. Using the proposed test specimens it was found that real dimensions of the trusses varies with size and orientation to the base platform. It was proposed and tested samples for rod tensile test made of SLM. Based on the real information about dimensions and mechanical properties of rods were predicted mechanical properties of lattice structures. A lot of mechanical tests were carried out to obtain the real mechanical properties. Test results and conclusions are described in the thesis.

This fact has been recently reflected in a fair amount of legal regulations governing this industrial branch and almost hysterical campaigns of various food-providing chains that are trying persuade the public that only and just their products are free of any such additives. At the same time, however, and quite effortlessly can each of us get quite opposite information that would definitely harm the aura of safety created round the food additives. It is evident that a typical man takes mostly subjective attitude in this chaos of opposing information which is supported by different fabulations or "reliable information". The aim of this thesis is to clarify the issue of food additives and their use in meat-based products that form one part of unhealthy eating habits in our society. The acquired...
