The invention relates to an ultrasonic district laminated added material manufacturing device and a method, and belongs to the technical field of added material manufacturing. A forming chamber system and a paper mold motion system are positioned in a frame and fixed on a baseplate thereof; a powder paving system is positioned above the forming chamber system and fixed on a middle support plate; and a mobile ultrasonic welding system and a laser scanning cutting system are fixed on a top support plate of the frame. The device has no need to adopt such high-energy emitting devices as high-power lasers and electronic beams, and converts ultrasonic vibration energy to friction energy, deformation energy and limited temperature rise among powder materials under static pressure; parts formed by the method are lower in residual stress and heat deformation; and the method can realize bonding of atoms among powder particles, can realize the added material manufacturing of high-strength metal or nonmetal three-dimensional parts, and in particular, is suitable for the added material manufacturing of amorphous metal materials. The method has such advantages as no need to protect gas in the forming process, no need of complex aftertreatment process after formation, and high forming precision.
