Additive Manufacturing Device and Method with Interlayer Ultrasonic Rolling Assisted Through in-situ Electromagnetic Induction Heating

Abstract

An additive manufacturing device and method with interlayer ultrasonic rolling coupled in-situ electromagnetic induction heating, the device includes an additive manufacturing equipment, a substrate turntable for supporting and adjusting a component's position, an ultrasonic rolling device and an electromagnetic induction heating device cooperated with a top of the component; an ultrasonic controller connected to the ultrasonic rolling device to set rolling parameters required, and an electromagnetic controller connected to the electromagnetic induction heating device to set a current intensity and an induction frequency required. The device and method utilize eddy currents generated by an alternating electromagnetic field to regulate component surface temperature, which can significantly reduce ultrasonic rolling resistance, improve interlayer strengthening efficiency, reduce interlayer strengthening costs, broaden the range of materials suitable for interlayer strengthening, close defects in AM metal components and improve component forming quality and density, and has a positive impact on AM metal materials.
