This invention provides a spatial acoustic wave manufacturing device, including a frame, an acoustic wave generating module, and a control module. The frame is equipped with a first X-axis guide rail, a second X-axis guide rail, a first Y-axis guide rail, a second Y-axis guide rail, a rotary platform, a Z-axis stepping electric cylinder, a robotic arm, and an ultrasonic actuating head. The control module and the above structures form a multi-degree-of-freedom motion system. This device enables the liquid tank carrying the workpiece and the ultrasonic actuating head to perform precise, multi-axis linkage relative motion in space, allowing the acoustic wave focus to be accurately positioned and continuously moved in three-dimensional space. This enables non-contact processing of workpieces with complex curved surfaces such as overhangs, internal cavities, spiral flow channels, and honeycomb grids, and allows printing without any physical support materials.
