1. A method of producing a treated article, comprising:
applying a layer of particles to a target surface, wherein at least some of the particles include a fusible polymer;
selectively binding particles of the layer by applying a liquid binder to a selected portion of the layer corresponding to a cross section of an article, wherein the liquid binder binds the particles in the selected portion to form a bonded portion;
repeating the steps of applying particles and selectively binding particles for a multitude of layers, wherein the repeating further comprises binding bonded portions of adjacent layers to obtain a bonded article; and
contacting at least a portion of the bonded article with a liquid heated to >T or a powder bed heated to >T and sintering the portion of the bonded article to form a treated article, wherein T is a temperature of >25° C., wherein the liquid is not a solvent or coreactant for the liquid binder and the fusible polymer, and the powder bed is different than the particles of the fusible polymer.
