Abstract: Devices, systems, and methods are directed to the use of vapor phase change in binder jetting processes for forming three-dimensional objects. In general, a vapor of a first fluid may be directed to a layer of a powder spread across a build volume. The vapor may condense to reduce mobility of the particles of the powder of the layer. For example, the condensing vapor may reduce the likelihood of particle ejection from the layer and, thus, may reduce the likelihood of clogging or otherwise degrading a printhead used to jet a second fluid (e.g., a binder) to the layer. Further, or instead, the condensing vapor may increase the density of the powder in the layer which, when repeated over a plurality of layers forming a three-dimensional object, may reduce the likelihood of slumping of the part during sintering.

Abstract: A method of metal additive manufacturing, including forming a three-dimensional object as a successive series of layers. At least some of the successive layers is formed by depositing a layer of build material powder on a work surface, depositing a predetermined pattern of fugitive fluid and depositing a predetermined pattern of binder fluid, wherein the predetermined pattern of fugitive fluid improves at least one characteristic of the three-dimensional part.

Abstract: Devices, systems, and methods are directed to the use of nanoparticles for improving fabrication of three-dimensional objects formed through layer-by-layer delivery of an ink onto a powder of metal particles in a powder bed. More specifically, the ink may include a colloid of nanoparticles of an inorganic material (e.g., a metal) in a carrier, and the colloid may be destabilized along one or more sections of at least one layer. Destabilization of the colloid may aggregate the nanoparticles along at least one layer to facilitate, for example, formation of an interface layer useful for separating the three-dimensional objects from associated support structures. Further, or instead, the aggregated nanoparticles may be useful for hardening a given layer to facilitate uniform distribution of a subsequent layer on top of the given layer. Thus, more generally, aggregation of the nanoparticles along the powder be may be useful for improving quality of the three-dimensional objects being fabricated.
