Optimizing the DED 3D Printing Process for Improved Microstructure and Mechanical Performance

The choice of processing parameters used for product fabrication in laser-based additive manufacturingAdditive manufacturing (AM) is as critical as the property requirements of the product is meant to conform to. Part qualification is dependent on establishing a reliable processing strategy to produce parts in a repeatable manner that conforms to the desired property requirements. This paper discusses the processProcess used to produce titaniumTitanium alloy samples with improved build integrity and mechanical propertiesMechanical properties. Samples fabricated at optimized parameters showed an optimized microstructureMicrostructure that reported less defectsDefects and improved mechanical propertiesMechanical properties, such as hardnessHardness and tensile propertiesTensile properties. The materialMaterials showed a decrease in stiffness, while the yield and tensile strengthsTensile strength showed improvements. The tensile elongation showed an improvement of 11% due toParameter optimization parameter optimizationOptimization.
