Özet:

The increasing demand for metal components with complex geometries and high quality has steered the development of various manufacturing technologies. As an emerging and innovative industrial production technology, Additive Manufacturing (AM) allows for realization of three-dimensional shapes with complex geometries based on a layer-by-layer incremental manufacturing concept with high degrees of customization compared to traditional metal manufacturing processes such as forming, cutting and casting. However, despite the numerous advantages associated with the use additive manufacturing (AM), the use of different combinations of key process parameters highly influence the printed part’s structural integrity and quality. As AM evolves rapidly, the reality is that, part failure rates can be quite high especially during the first-time production of 3D metal parts especially due to the use of unoptimized process parameters. This implies that to make the metal AM processes predictable and reliable for the successful production of metal parts, the costly and time-consuming trial and error attempts have to be eliminated by the use of part build design optimization and simulation tools to prevent material wastage and accurately predict the behavior of a build part before initiating the printing process.
