A 3D printing system uses lasers for manufacturing parts in metal additive manufacturing, such as powder-bed fusion. The lasers may be arranged on a dome-shaped structure, vertically above powdered metal. The dome-shaped structure, and arrangement of the lasers on the dome-shaped structure, permits a higher density of the lasers to be packaged onto the 3D printing system and increases a utilization of the lasers during manufacturing. Mirror(s) allow the lasers to be selectively, and individually, steered towards particular locations within the powdered metal in which the parts are manufactured. Lens(es) may actuate to adjust a spot size of laser beams emitted by the lasers. Imaging sensor(s) may also monitor the powdered metal, such as a melt pool of the powdered metal, for feedback and use in driving and steering the lasers.
