In molten metal jetting, where droplets of metal are jetted to 3D print a part, each layer may be traversed each successive layer with a normalizing grinding wheel or other leveling device such as a layer to level each successive layer, and/or the melt reservoir or printing chamber may be filled with an anoxic gas mix to prevent oxidation.

The present invention discloses a laser shock forging and laser cutting composite additive manufacturing device and method. The device forms two different light guide systems by splitting an output laser beam of a laser device into two laser beams through a beam splitter system. The first light guide system splits a laser beam into a third laser beam and a fourth laser beam which are respectively applied to laser 3D (3-Dimensional) printing and laser cutting. The second laser beam is applied to laser shock forging. A three dimensional model is built according to individual design requirements of a part. Layer-by-layer slicing treatment is performed to acquire slice contour information, so as to determine a layered contour and internal complex structures such as a cavity, a pipeline and a cold pipe of the part through laser cutting. The third laser beam forms an Nth layer of slice through 3D printing, and the second laser beam performs synchronous laser shock forging in an optimal temperature region. The fourth laser beam works when the thickness of each layer of slice or each slice layer meets the requirements, thereby guaranteeing the dimension accuracy and the surface quality and realizing high-rigidity, high-accuracy and high-efficiency 3D printing. The device has the advantages of high machining efficiency, high quality and long service life.
