    Abstract: A method for making an article is disclosed. According to the method, a digital model of the article is generated. The digital model is inputted into an additive manufacturing apparatus comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a powder to fuse the powder to form the article corresponding to the digital model. The powder particles individually include a composite core including a first phase of a first metal and a second phase of a ceramic. A first shell including a second metal is disposed over the core.

    Abstract: A method of manufacturing a component includes making a preform from a powdered material, the preform having a density in a range from 70 to 95% of theoretical density of the material, The method also includes sintering the preform using a Field Assisted Sintering Technique (FAST) process to produce a component having a density of greater than 97% of the theoretical density of the material. Components, in particular low aspect components, formed by said method are also described.

    Abstract: A method of making an article is disclosed. According to the method, an energy beam is directed to a build location on a substrate, and a first powder material is delivered to the build location on the substrate and melted with the energy beam. A second powder material is delivered to the build location on the substrate over the first material and melted with the energy beam. The direction of the energy beam and delivery and melting of the first and second powders is repeated at multiple build locations on the substrate to form a solid surface of the article of the second material. The solid surface comprising the second material is subjected to a finishing process.

    Abstract: An example method of making a component includes providing a digital model of a component to a software program, the software program operable to slice the digital model into digital layers and raster each digital layer into digital segments, the digital segments delineated by digital raster lines. The method further includes depositing a first layer of powdered material onto a platform, compacting the first layer of powered material into a first compacted layer, sintering the first compacted layer along lines corresponding to the digital raster lines using a laser, wherein the laser operates at a first power and a first scan speed, and sintering the first compacted layer along a perimeter of the first compacted layer using the laser to form a first unitary layer, wherein the laser operates at a second power and a second scan speed, wherein the ratio of the first power to the second power is less than about 3. An apparatus for making a component is also disclosed.

    Abstract: A structure for preventing a scan by a beam is provided. The structure includes a primary material forming the structure. The primary material includes a first mass attenuation coefficient enabling the primary material to be penetrated by the beam. The structure also includes a matrix of dense particles within the primary material. The dense particles include secondary materials different than the primary material. The secondary materials comprise a subsequent mass attenuation coefficient that is greater than the first mass attenuation coefficient of the primary material. The subsequent mass attenuation coefficient enables the dense particles to attenuate the beam to distort the scan.
