The purpose of this research was to measure the equation of state for additively manufactured (AM) and forged 304L stainless steel. An understanding of the dynamic behavior of AM metals is integral to their timely adoption into industrial and governmental applications. The Hugoniot of the AM 304L was compared to that of the forged 304L. This comparison enabled us to determine the sensitivity of the equation of state to processing parameters and the resulting microstructure. Our results show that there is a measurable difference in the Hugoniot between the AM 304L and forged 304L. The shock wave velocities for the AM 304L were found to be slower than those for the forged 304L at similar particle speeds perhaps because of the presence of porosity in the AM 304L. While our measurements of density showed no distinct trend toward a measurable decrease in density in the AM 304L, there was a fair amount of scatter in these results.
