Characterization of stainless steel components produced by Direct Energy Deposition with an oscillating scan strategy

The objective of this work is to obtain a reliable process to manufacture addictively AISI 316L steel with Direct Energy Deposition coupled with an innovative oscillating scan strategy. The experiment is designed in multiple phases to understand first the correct production parameters to obtain satisfactory depositions, and then analyse the resulting components to understand their metallurgical characteristics and evaluate the overall quality of the prints. Results suggest that this technology can improve production times and the versatility of a single machine, providing quality print with different metallurgical characteristics out of the same print head.
