摘要： An optical system may include a first optical assembly and a first scan field expansion assembly. The first optical assembly may include or may be configured as a first flat-field lens. The first flat-field lens may have a first nominal scan field with a first flat focal plane. The first scan field expansion assembly may include one or more first field-expanding optical elements configured to provide a first expanded scan field coinciding with the first flat focal plane. The first expanded scan field may have a cross-sectional width and/or area that exceeds a corresponding cross-sectional width and/or area of the first nominal scan field. A method of additively manufacturing a three-dimensional object may include directing a first energy beam through the first optical assembly, and directing the first energy beam through the first scan field expansion assembly.

摘要： Methods of additively manufacturing components include providing a first control command and/or a second control command to a cart selected from among a plurality of carts. The first control command may be configured to cause the selected cart to autonomously drive or fly to a construction container selected from among a plurality of construction containers and to receive automatically the selected construction container, and, upon the selected cart receiving automatically the selected construction container, to autonomously drive or fly the selected cart to a construction apparatus selected from among a plurality of construction apparatuses. The second control command may be configured to cause the selected cart to autonomously drive or fly to the selected construction apparatus and to receive automatically a construction container containing a component having been additively manufactured by the selected construction apparatus upon the selected construction apparatus automatically discharging the construction container containing the component.
