Abstract
An additive manufacturing system includes an apparatus to facilitate production at the microscale using metal sheet as feedstock. The additive manufacturing system uses energy from a pulsed laser beam for ejection of metallic droplets to consolidate a part in a layer-by-layer manner. The system may include an enclosure, a stage, a substrate, a feedstock advancement device, an optically transparent support, and a controller.
Claims36
An additive manufacturing system, comprising:
- an enclosure, the enclosure defining an inlet, an exhaust, and an aperture and comprising a substrate upon which a workpiece is to be formed and an optically transparent support disposed between the aperture and the substrate;
- a pulsed laser, disposed outside the enclosure, positioned to emit one or more pulses through the aperture and into the enclosure;
- a feedstock comprising a sheet or ribbon of material that is moveable with respect to the transparent support;
- a feedstock advancement device, at least partially disposed within the enclosure, to advance the feedstock within the enclosure and to maintain the feedstock adjacent the optically transparent support;
- and
- a controller to cause the pulsed laser to emit one or more pulses through the aperture and the optically transparent support to impinge upon a selected portion of the feedstock to liquefy the selected portion of the feedstock and discharge a droplet of the material from the feedstock onto the substrate or onto a workpiece on the substrate.
