摘要： A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

摘要： Sensor values captured by a sensor device are determined, one or more regions of a three-dimensional component having a deviation from an intended value are determined based at least in part on build coordinates for additively manufacturing the three-dimensional component corresponding to the sensor values, and a quality of the three-dimensional component is evaluated based at least in part on the one or more regions of the three-dimensional component having a deviation from the intended value. The sensor values correspond to an electromagnetic spectrum emitted by a melt pool formed by exposing a powder bed to a beam of radiation emitted from a laser apparatus, with the beam of radiation generating the melt pool in a melt region of the powder bed.

摘要： Disclosed herein are methods, apparatus, and systems for providing an optical beam delivery system, comprising an optical fiber including a first length of fiber comprising a first RIP formed to enable, at least in part, modification of one or more beam characteristics of an optical beam by a perturbation assembly arranged to modify the one or more beam characteristics, the perturbation assembly coupled to the first length of fiber or integral with the first length of fiber, or a combination thereof and a second length of fiber coupled to the first length of fiber and having a second RIP formed to preserve at least a portion of the one or more beam characteristics of the optical beam modified by the perturbation assembly within one or more first confinement regions. The optical beam delivery system may include an optical system coupled to the second length of fiber including one or more free-space optics configured to receive and transmit an optical beam comprising the modified one or more beam characteristics.

摘要： Additive manufacturing processes, systems and three-dimensional articles include the formation of voxels and/or portions of three-dimensional articles with different properties relative to other voxels and/or portions. The processes generally include changing one or more laser beam parameters including power level, exposure time, hatch spacing, point distance, velocity, and energy density during the formation of selected voxels and/or portions of the three-dimensional articles. Also disclosed are processes that include an additive manufacturing process that provides localized secondary heat treatment of certain voxels and/or regions at a temperature below the melting point of the three-dimensional article but high enough to effect a localized property change.

摘要： A laser power control method for additive manufacturing includes a pre-processing component and an intra-processing component. The pre-processing component creates in the system controller a machine code expressed additive-path-with-geometry-metadata that includes a path description. The path description represents the path of the beam source on the build and includes a geometry index for the build. The intra-processing component calculates required power for the beam at intervals and events on the beam path based upon the additive-path-with-geometry-metadata and calculations of the energy balance at the melt pool and the total energy for each point P(s) on the path.
