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.

Adhesive compositions and their use in 3D printing

Described herein are methods and compositions for forming three-dimensional objects via material jetting processes, the methods including the repeated steps of selectively depositing a liquid thermoset material onto a surface from a nozzle of at least one jetting head in a first specified direction and exposing at least a portion of the liquid thermoset material to a source of actinic radiation in order to form a three-dimensional object from the cured thermoset material, wherein the jetting head is configured to eject droplets of the liquid thermoset material from the nozzle at prescribed elevated operating temperatures, and wherein the liquid thermoset material is chosen so as to possessing prescribed viscosity and rheological characteristics.
