    The objective of this paper was to investigate the effects of curing parameters (i.e., temperature and time), on the permeability and mechanical strength of the printed molds. Several sets of samples were hence produced with a state-of-the-art 3D printer using well-characterized silica sand and furan resin binder. Then, experiments were performed in which the evolution over time of the three ...
