Abstract

Laser powder bed fusion (LPBF) is one of a group of manufacturing technologies capable of producing complex structures and surfaces in small batches and with reduced lead time. Materials ranging from light metals (e.g., aluminum alloys) to high temperature alloys can be used. This work focuses on nickel super alloy 625 (IN625) and explicitly on characterization of surfaces that are subsequently covered by additional layers. The surface features described here have not, to our knowledge, been previously described in the literature. The lateral and vertical scales are such that powder layer thickness will be significantly modulated while spreading the next layer of powder. This is likely to affect local material properties in the subsequent layer(s).
