Summary

Topology optimization is a design method and a type of structural optimization. The structural composition and topology of a construction approach its ideal form. Complex shapes and the modern need for efficient design are unresolved problems for classical production technologies. With the application of additive manufacturing combined to topology optimization, the engineer can easily and economically acquire a complex geometry with a reduced amount of material, without detracting from the quality of the product. This diploma thesis expands on the method of topology optimization, as implemented via the Siemens software NX 12. In addition, additive manufacturing is analyzed and linked to the topology optimization method in the individual steps of a construction. In conclusion, the importance of topological optimization and prosthetic technologies are highlighted.In particular: In the first chapter, there is an introductory report, providing a general definition of the design process. The second chapter offers a detailed description of additive manufacturing technologies. The third chapter introduces the concept of topology optimization and gives a general definition. The fourth chapter presents the NX 12 Nastran software package and explains the essential processes involved in setting up topology optimization. Chapter five describes two different instances of topology optimization solutions. Finally, the sixth chapter summarizes the thesis and presents its main conclusions.
