In various embodiments, a water-based binder solution for use in additive manufacturing, includes a thermoplastic binder. The thermoplastic binder includes a first polymer strand having a weight average molecular weight (Mw) of from greater than or equal to 5,000 g/mol to less than or equal to 15,000 g/mol, a second polymer strand having a weight average molecular weight of from greater than or equal to 10,000 g/mol to less than or equal to 50,000 g/mol, and a third polymer strand having a weight average molecular weight of from greater than or equal to 1,000 g/mol to less than or equal to 5,000 g/mol. The binder solution further comprises from greater than or equal to 0.1 wt % to less than or equal to 5 wt % of a non-aqueous solvent having a boiling point of greater than 100° C.
