Abstract
A three-dimensional (3D) printer and method are provided, including a substrate, a liquid deposition device configured to deposit a liquid dispersion including a suspension of a particulate material in a liquid vehicle, the liquid vehicle including a solvent but devoid of a binder material, onto the substrate to form a non-patterned layer on the substrate, a solvent removal device configured to remove at least a portion of the solvent from the liquid vehicle from the non-patterned layer to form a dried non-patterned layer, and a liquid binder print head configured to deposit a liquid binder onto the dried non-patterned layer to form a printed pattern on the dried non-patterned layer.
