Popis: In this study, a high-value-added recycled α-hemihydrate gypsum (α-RHG) generated from WGP using the atmospheric pressure hydrothermal method (APHM) was utilized to manufacture a 3D printed material. The univariate and combined effects of affordable and high-performance glidants, including hydrophobic nano-silica (HNS) and soluble starch (SS), on the flowability of α-RHG were evaluated experimentally and modelled. The results revealed that the flowability of α-RHG can be enhanced by the proper univariate addition of HNS (e.g.,
