1. A method of forming an object using binder jet additive manufacturing, the method comprising:
forming a layer of powder within a build chamber;
generating a first fluid in a vapor phase within the build chamber;
adjusting or maintaining an environment within the build chamber to affect a condensation of the first fluid from the vapor phase to a liquid phase;
condensing the first fluid from the vapor phase to the liquid phase on at least a portion of the layer of powder; and
traversing a print head relative to the layer of powder and depositing a predetermined pattern of a binder in the layer of powder.
