Porous metals combine low density with high energy absorption and thermal insulation, which makes them suitable for demanding structural applications such as crash-absorbing inserts in automotive components. However, to fully exploit their potential, reliable methods are needed to join these porous materials with dense structures to form hybrid porous components. Additive manufacturing technologies, like laser-based Directed Energy Deposition (DED-LB), offer the ability to manufacture various geometries and materials onto porous metals. In this study, DED-LB is used to deposit dense material layers on porous metallic substrates. The porosity was mimicked by drilling holes with defined geometry into 316L stainless steel substrates. To study the influence of different pore arrangements, the center-to-center distance between the holes was varied while keeping the pore geometry constant. Three process strategies were evaluated: laser remelting (LR) for smoothing the surface, direct DED-LB, and combinations thereof, with and without skin on porous metals using directed energy deposition.
