| description | Devices, systems, and methods are directed to the use of nanoparticles for improving strength fabrication of three-dimensional objects formed through layer-by-layer process in which an ink is delivery of a binder delivered onto successive layers of a powder of inorganic particles in a powder bed. More specifically, nanoparticles of inorganic material can may be introduced into one or more layers of the metal powder in the powder bed and thermally processed to facilitate sinter necking, in the powder bed, of the metal particles forming the three-dimensional object. Such sinter necking in the powder bed can may improve strength of the three-dimensional objects being fabricated and, also or instead, can may reduce the likelihood of defects associated with subsequent processing of the three-dimensional objects (e.g., slumping and shrinking in a final sintering stage and/or inadequate densification of the final part). |
