Processing of aluminium alloys using 3D technology selective laser melting

This bachelor thesis deals with finding of appropriate process parameters for minimizing porosity with SLM technology for processing aluminum alloy 6061. The search part deals about the issue of additive manufacturing aluminum alloys and evaluation of porosity measurements of relative density. Based on general knowledge were proposed test samples produced by sintering of metallurgical powder using a laser with ytterbium optical fiber. In this work was used high power of laser up to 400 W, with which 6061 alloy was not been in terms of porosity in detail tested yet. As the result, the technological parameters dependence on relative density and the overview of this alloy processing by SLM technology was determined
