Abstract Vom Untergang zur See zu handeln, führt in der westlichen Erzähltradition seit Homer auf kosmologische und existentielle, politische und ökonomische Belange. Will man von einem regelrechten ,,Schiffbruch-Narrativ“ sprechen, dann ist dieses nicht nur durch eine longue durée motivischer und struktureller Beständigkeit ausgezeichnet, sondern auch durch einen hohen Grad an sprachlich-formaler Selbstreflexivität und seit der Neuzeit durch die Engführung nautischer mit poetischen Innovationen. Wendepunkte markiert das Scheitern nunmehr in seefahrts- und auch literaturhistorischer Hinsicht, weshalb man, wie im Portugal der Entdeckerzeit, von einem maritimen ,,discurso“ sprechen kann.In the Western narrative tradition since Homer, relating to sea losses leads to cosmological and existential, political and economic concerns. The ,,shipwreck narrative“ is characterized by a long-lasting motivic and structural consistency. But furthermore, it exhibits a high degree of linguistic and formal self-reflexiveness, and since modern times, it brings together nautical with poetic innovations. The sinking now marks turning points in terms of maritime navigation as well as literary history, which is why, as in Portugal of the time of discovery, one can speak of a maritime ,,discurso“.

This paper deals with finding the building parameters for manufacturing of fine structures with regard to their size precision and structural consistency. Practical use of these structures can be found in areas such as microelectronics, fine mechanics and automotive. Very fine structures with thickness lower than 0.3 mm are very hard to be manufactured due to the limitations of Selective Laser Melting (SLM) technology. These limitations lie in building parameters including mean size and shape of the powder particles, diameter of laser spot and scanning speed. Practical part of the work consists of printing the testing matrices from AlSi12 material with different building parameters for each element. Final products are then evaluated using scanning electron microscope in order to verify final size and structural properties of the specimens. Thanks to these tests, it was possible to find actual border of the technology for given type of powder. Structure with minimal thickness and sufficient strength was found to be 0.21 mm. Moreover, the method for finding parameters for manufacturing of fine structures is applicable for other types of materials.
