Abstract: Methods of simulating additively manufacturing an object may include generating a simulated additively manufactured object based at least in part on a plurality of approximate consolidation domains that respectively correspond to a plurality of consolidation tracks determined from one or more digital representations of an additively manufactured object, and determining a predictive inference with respect to one or more material properties of the object to be additively manufactured based at least in part on the simulated additively manufactured object. Methods may include generating, for an object to be additively manufactured, a CAD file and/or a build file based at least in part on a simulated additively manufactured object and/or based at least in part on one or more predictive inferences with respect to one or more material properties of the object to be additively manufactured. An object may be additively manufactured based at least in part on a simulated additively manufactured object and/or a CAD file and/or the build file corresponding thereto.

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 of making a hollow metal component comprising the steps of providing at least one core comprising a first side and a reverse side; utilizing a first metal spray process to apply at least one metal or metal alloy to the first side of the core, resulting in a partially-formed structure comprising a first side and a reverse side; and utilizing a second metal spray process to apply at least one metal or metal alloy to the reverse sides of the partially-formed structure and the core, resulting in a rough structure. A hollow metal component comprising a first side having interior and exterior surfaces, a reverse side having interior and exterior surfaces, the interior surfaces of the first side and the reverse side defining at least one cavity. The component is integrally formed and has regions comprising relatively different material compositions, the regions having gradual transitions of materials therebetween.

Abstract: Process for producing a titanium alloy material, such as a titanium aluminum alloy, are provided. The process includes reduction of TiCl4), which includes a titanium ion (Ti4+), through intermediate ionic states (e.g., Ti3+) to Ti2+, which may then undergo a disproportionation reaction to form the titanium aluminum alloy.

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.
