摘要： A method of making an integrally bladed rotor with hollow blades. A plurality of segmented layers are sequentially placed to form each one of a plurality of blades on a radially outward surface of a hub. This is done using an additive manufacturing process. The placement of the segmented layers also comprises omitting portions of one or more of the plurality of segmented layers to form one or more cavities and intermittently removing a quantity of particles from the one or more cavities using an evacuation tool.

摘要： A 3D printer that is mostly twenty to thirty times faster than existing 3D printers. Pixel-based Raster images are converted into Scalable Vector Graphic (SVG) images, which are then categorized as lines, curves and surface areas. For each category, faster printing methods for printing with pre-formed shapes such as rods, boards, arcs, etc., are disclosed. Pre-formed shapes may be made of plastic/thermoplastic/polymer or sintering materials, as desired. Sintering materials may be cladded/coated with appropriate materials such as solder, copper, and thermoplastics. The new print-head, which has a fixed portion and a replaceable portion, has a mechanism to draw upon pre-formed shapes to print. The replaceable portion has varying shapes and sizes of placement holes, and a mechanism to signal which replaceable portion has been mounted. The print-head incorporates mechanisms to heat and tack the pre-formed shapes. The invention discloses methods to use multiple print-heads to further speed up printing.

摘要： A process for growing a substrate (24) as a melt pool (28) solidifies beneath a molten slag layer (30). An energy beam (36) is used to melt a powder (32) or a hollow feed wire (42) with a powdered alloy core (44) under the slag layer. The slag layer is at least partially transparent (37) to the energy beam, and it may be partially optically absorbent or translucent to the energy beam to absorb enough energy to remain molten. As with a conventional ESW process, the slag layer insulates the molten material and shields it from reaction with air. A composition of the powder may be changed across a solidification axis (A) of the resulting component (60) to provide a functionally graded directionally solidified product.

摘要： A system for and a method of controlling filler wire is provided. The system includes a high intensity energy source configured to heat at least one workpiece to create a molten puddle on a surface of the at least one workpiece. A filler wire feeder is configured to feed a filler wire into said molten puddle, and a travel direction controller is configured to advance the high intensity energy source and the filler wire in a travel direction to deposit the filler wire on the at least one workpiece. The system also includes a filler wire controller configured to move the filler wire in at least a first direction during the feeding and advancing of the filler wire. At least the first direction is controlled to obtain a desired shape, profile, height, size, or an admixture of a bead formed by the molten puddle.
