Abstract: Methods provide for fabricating objects through additive manufacturing in a manner that compensates for deformations introduced during post-print processing, such as sintering. An initial model may be divided into a plurality of segments, the initial model defining geometry of an object. For each of the segments, modified geometry may be calculated, where the modified geometry compensates for a predicted deformation. Print parameters can then be updated to incorporate the modified geometry, where the print parameters define geometry of the printed object (e.g., configuration settings of the printer, a tool path, an object model). The object may then be printed based on the updated print parameters.

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, local densities of the powder of each layer may be determined and used as a basis for selectively distributing the ink including nanoparticles to increase density of one or more portions of the respective layer as compared to density of the respective portion of the layer prior to the selective distribution of the ink. Thus, the selective distribution of the ink including the nanoparticles may reduce density variations in each layer of three-dimensional objects being fabricated. In turn, such a reduction in density variation associated with the fabrication of three-dimensional objects may reduce the likelihood of defects (e.g., through unintended variations in shrinkage rates) associated with subsequent processing of the three-dimensional objects.
