Abstract:This article demonstrates the effect of varying the maximum grain size and the layer thickness of the particle bed on hardened state properties in Selective Cement Activation (SCA). The compressive strength and geometry (deviation from nominal geometry, surface roughness) are analyzed. Supplementary investigations (μCT, μRFA) are performed to explain the causes of the observed effects. It is found that the compressive strength of the manufactured specimens increases with decreasing layer thickness. This is att… Show more
