Abstract

The processes of design and manufacturing continue to expand with extraordinary opportunities due to the emergence and development of additive manufacturing technologies. Additive manufacturing processes radically differ from traditional manufacturing methods and require a completely new engineering approach. As a result, new possibilities emerge, allowing the creation of geometries that were previously difficult or impossible to produce using other technologies. Significant application opportunities exist in fields such as medicine and many sectors of industry due to this advancement. The range of materials used in additive manufacturing is constantly improving and expanding, although the most significant results are in the area of industrial applicability, which is the focus of this research. It is important to mention that besides Selective Laser Sintering / Selective Laser Melting (SLS / SLM), Fused Filament Fabrication (FFF) is worth considering for producing metal parts, due to lower costs and the possibility of manufacturing larger parts. The aim of the research is to examine the microstructural and macrostructural characteristics of finished components produced by FFF.
