摘要： An apparatus and process for formation of a multicomponent metal alloy ingot or product in which granulated metal feedstock, under a high pressure inert environment, is introduced onto a rotating platen or previously deposited layer on the rotating platen. As the granulated feedstock is deposited on the platen, the platen is rotated such that a segment of the platen having the feedstock thereon passes through an energy generator field such as a melting laser beam or eddy current induction melting field. As it passes it is melted to form an arcuate segment of melt. The melt is then rotated out from under the energy beam and cooled into a solid state of the desired alloy as a next contiguous segment of feedstock is introduced and the process repeated until a layer is formed. The platen may then be indexed lower and a new layer is formed in the same manner.

摘要： A method for producing a three-dimensional component by means of a laser melting process, in which the component is produced by consecutively solidifying individual layers made of building material by melting the building material, wherein said building material can be solidified by the action of radiation, wherein the melting area produced by a punctiform and/or linear energy input is detected by a sensor device and sensor values are derived therefrom in order to evaluate the component quality. The sensor values detected in order to evaluate the component quality are stored together with the coordinate values that locate the sensor values in the component and are displayed by means of a visualization unit in two- and/or multi-dimensional representation with respect to the detection location of the sensor values in the component.

摘要： A system for manufacturing a build object includes an additive manufacturing tool configured to utilize a powdered reactive material to construct the build object. The powdered reactive material includes a plurality of powder beads, wherein each powder bead has a bead diameter that is substantially similar to an ideal bead diameter. The system further includes apparatus configured to selectively shield the build object during additive manufacturing of the build object, by the additive manufacturing tool, using an inert gas. The ideal bead diameter is configured to be a bead diameter at which ignition of the powdered reactive material is inhibited, upon oxidation of the powdered reactive material.

摘要： This invention provides systems and method for monitoring three-dimensional printing of printing material. A system comprises two essentially coplanar and electrically conductive electrodes and a substantially electrically non-conductive substrate, which provides a printing surface. The proximate edges of the electrodes, which are on the surface, are essentially parallel and separate by a distance ranging from 5 mm to 300 mm. Each electrode is substantially smaller in area than the substrate. The system also comprises a plurality of layers, which are formed layer-by-layer by the printing, and are derived from the printing material. The electrodes are electrically oppositely charged, as enabled by an alternating electric current between the two electrodes. The current partly flows in the layers. The two electrodes exhibit between them a capacitance ranging from 0.1 pF to 10 nF. The capacitance is essentially in a direction parallel to the surface and substantially perpendicular to the proximate edges.

摘要： A debinder provides for debinding printed green parts in an additive manufacturing system. The debinder can include a storage chamber, a process chamber, a distill chamber, a waste chamber, and a condenser. The storage chamber stores a liquid solvent for debinding the green part. The process chamber debinds the green part using a volume of the liquid solvent transferred from the storage chamber. The distill chamber collects a solution drained from the process chamber and produces a solvent vapor from the solution. The condenser condenses the solvent vapor to the liquid solvent and transfer the liquid solvent to the storage chamber. The waste chamber collects a waste component of the solution.
