Tooling in the die and mould industry is subjected to high-wear high-temperature environments, which often leads premature failure of this high-added-value tooling. When severe damage occurs, an alternative replacing whole component consists repair by laser-directed energy deposition (L-DED). For that end, intermediate layers are commonly employed as buffer material, where introducing a functio...

Abstract The paper focuses on researching the effect of fatigue loading metallic structure, lifetime, and fracture surface topographies in AISI H13 steel specimens obtained by selective laser melting (SLM). topography surfaces was measured over their entire area, according to total area method, with an optical three-dimensional measurement system. results SLM 3D printed were compared those repo...
