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: A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.

摘要: An additive manufacturing system includes at least two high power lasers to generate beams. A phase patterning unit is used to receive and alter phase of a beam from at least one of the two high power lasers. At least one phase patterned beam can be mixed with another beam at a print the print bed. In some embodiments, beams are moved with respect to the print bed by changes in phase patterns from the phase patterning unit. In other embodiments, phase patterns from the phase patterning unit can be used for simultaneous printing of multiple layers.

摘要: A method and an apparatus pertaining to polarization combining in additive manufacturing may involve emitting two or more beams of light with a first intensity. Each of the two or more beams of light may be polarized and may have a majority polarization state and a minority polarization state. A respective polarization pattern may be applied on the majority polarization state of each of the two or more beams of light. The two or more beams of light may be combined to provide a single beam of light.

摘要: An additive manufacturing method that can use a two-dimensional energy patterning system is disclosed. Information related to a part is provided, with the information including CAD files, material type, selected additive manufacturing process type, and tolerances of selected design features. Manufacture of a part is simulated and compared to selected design tolerance. If the simulated manufactured part is outside selected design tolerances, simulation parameters can be adjusted until results indicate the simulated manufactured part is within selected design tolerances. In certain embodiments, manufacturing the part uses a real-time sensor monitoring system, along with post processing analysis of selected design features to improve simulated manufacture of the part.
