Abstract

Powder-bed 3D printing technology is attractive as it allows to build complex structures and optimize cost and time. The liquid is sprayed to bond the powder bed at pre-determined positions layer by layer. After print, the nonbonded particles are removed during post-processing. From a material point of view, it is crucial to understand the interactions between liquid and powder bed. Indeed, the spreading of water in the powder bed impacts the hardened performances of the printed elements. In the current work, we first measure the onedimension water penetration over time for pure cement powder, pure plaster powder and a modified plaster powder suitable for 3D printing. We then show the hardened morphology of water penetrated and bonded area. Our results and analysis suggest that for common inorganic reactive powder, the penetration depth is higher than the one required to control the shape. Thus, it is necessary to modify transfer properties in order to control the liquid penetration depth. We furthermore identify key parameters to design applicable dry powder mixtures for 3D powder-bed printing technology.
