Composite ultrasonic deposition additive manufacturing device and method

Abstract

The invention relates to a composite ultrasonic deposition additive manufacturing device and method and belongs to the field of additive manufacturing. A three-axis movement system is fixed into a rack and located above a base plate of the rack. An ultrasonic deposition printing head is located above the three-axis movement system and fixed to a supporting plate. A wire guiding pipe is located between and connected with the ultrasonic deposition printing head and a wire feeding device. A wire cutting device, the wire feeding device and a material roller are fixed to a cross beam at the top of the rack. According to the composite ultrasonic deposition additive manufacturing device and method, no outer heating source is needed, combination between atoms between deposition wires can be achieved through ultrasonic vibration, and a three-dimensional solid part with a good comprehensive mechanical property is directly formed in a solid mode; deposition forming is not limited by material varieties, and direct near-net forming of a composite functionally graded material can be achieved; and accumulation forming is conducted layer by layer through the fine wire material, the forming precision is high, no complex aftertreatment process is needed, and the composite ultrasonic deposition additive manufacturing device and method have wide application prospects in the fields such as aviation, automobiles and biomedical treatment.
