Abstract: Adhesive compositions comprising an aqueous dispersion of an acrylic polymer are disclosed, with such compositions having particular applicability in additive manufacturing processes, such as three-dimensional (3D) printing, including Fused Filament Fabrication (FFF). In particular, the compositions address drawbacks associated with an improper degree of adhesion between a thermoplastic build material and build plate, which decrease the quality of printed objects. In representative aqueous dispersions, the solids content of at least about 5 wt. % and also most about 95 wt. % of the acrylic polymer is solubilized, with the balance of this polymer comprising dispersed solid particles.
