Jet angle controllable ultrasonic droplet jetting additive manufacturing device and method

Abstract

The invention relates to jet angle controllable ultrasonic droplet jetting additive manufacturing device and method, belonging to the field of additive manufacturing. The device is characterized in that a base is installed at the bottom; a jet tank is installed on the base; a focused ultrasonic transducer is installed in the jet tank; a base plate is fixed below wafer bearing platforms and above the jet tank; the wafer bearing platforms are installed on a Z-direction workbench; the Z-direction workbench is installed on the base; the jet tank is communicated with a liquid storage tank; a high-precision injection pump is connected with a feeding head; through focused ultrasound, liquid overcomes the surface tension and jets droplets from the liquid level; the power of four focused ultrasonic vibrators of the focused ultrasonic transducer is controlled by a computer and the focused ultrasonic vibrators interact and then change the jet angles of the droplets to jet the droplets to different positions on the base plate; a Z-axis motion platform cooperates with different jet angles to complete printing of different position points on the base plate. The device and the method have the effects of improving the printing precision and ensuring the physical and chemical properties and other properties of formed parts without needing print heads, thus avoiding pollution and cleaning difficulty of liquid materials.
