| Abstract Scope |
Selective laser melting (SLM) is among the top additive manufacturing techniques for fabricating low-volume components with high density and superior strength. The current work investigates the uniformity of microstructure and mechanical properties across different locations within SLM-printed 316L stainless steel and Inconel 718 forging preform. Samples were taken from three distinct locations: corner, face-center, and body-center. X-ray diffraction (XRD), optical, and scanning electron microscopy revealed consistent microstructure and XRD patterns throughout the SLM-printed blocks for both alloys. The study conducted density measurements, hardness tests, tensile testing, and ultrasonic testing to further evaluate the influence of location on the printed parts. The results demonstrated high relative density (> 99%), elevated hardness, superior strength, and high wave speed and confirmed uniformity within the blocks. This investigation is a step forward in ensuring uniformity and validating the reliability of SLM-printed components for a wide range of applications from aerospace and automotive to biomedical implants. |
