Abstract
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.
Claims36
An additive manufacturing system, comprising:
- at least two high power lasers to generate beams;
- a phase patterning unit to receive and alter phase of a beam from at least one of the two high power lasers;
- and
- wherein mixing of at least one phase patterned beam with another beam occurs at a print bed.
An additive manufacturing system that recycles laser power, comprising:
- at least two high power lasers to generate beams, with at least some beams being partially mixed;
- a phase patterning unit to receive and alter phase of a beam from at least one of the two high power lasers;
- and
- wherein mixing of at least one phase patterned beam with another beam occurs at a print bed and at least some unmixed beams are recycled to provide further beam patterning.
An additive manufacturing switchyard system that redirects laser power, comprising:
- at least two high power lasers to generate two-dimensional image forming beams, with at least some two-dimensional image forming beams being redirected by the switchyard system for reuse or phase mixing;
- a phase patterning unit to receive and alter phase of a two-dimensional image forming beam from at least one of the two high power lasers;
- and
- wherein mixing of at least one phase patterned beam with another beam occurs at a print bed.
An additive manufacturing method, comprising:
- generating beams using at least two high power lasers;
- positioning a phase patterning unit to receive and alter phase of a beam from at least one of the two high power lasers;
- and
- mixing at least one phase patterned beam with another beam at a print bed.
