Abstract: A method of manufacturing a three-dimensional target object may include forming a shell from loose machining powder using an additive manufacturing process and subjecting the shell to a densification process to form a target object. The shell may define an enclosure that contains additional machining powder. The densification process may include causing metallurgical bonding between the shell and additional machining powder contained in the enclosure defined by the shell and shrinking and/or distorting the shape of the shell to conform the target object to a three-dimensional model for the target object. The shell may include a plurality of layers and/or parts that differ at least in respect of density. The plurality of layers and/or parts may be configured based at least in part on the shrinking and/or distorting to the shape of the shell needed to conform the target object to the three-dimensional model for the target object.

Abstract: A method for manufacturing a three-dimensional part. The method includes: performing partial densification processing on loose machining powder, to form a densified and sealed enclosure, where there is still loose machining powder accommodated inside the enclosure; and performing overall densification processing on the enclosure and the machining powder inside the enclosure, so as to implement metallurgical bonding between the machining powder inside the enclosure and the enclosure during the densification, thereby forming a target three-dimensional part.
