Abstract

The invention discloses an ultrasonic vibration assisted 3D printing method, belongs to the technical field of 3D printing, and relates to a device and method based on ultrasonic vibration assisted 3Dprinting. According to the method, the specially-made ultrasonic-assisted 3D printing device is adopted, and the device is composed of a 3D printing mechanism and an ultrasonic vibration structure. According to the ultrasonic vibration assisted 3D printing method, the 3D printing device is assembled firstly, and when ultrasonic vibration is assisted for 3D printing, firstly, a printing material is fed into a printing nozzle through a stepping motor; the printing material in the nozzle is converted into a molten state from a solid state under the action of a high temperature and is extruded toa printing bottom plate through the nozzle; and at the moment, under the control of a six-degree-of-freedom mechanical arm and an ultrasonic generator, an ultrasonic amplitude-variable rod carries out the ultrasonic vibration on the material which is not completely solidified, so that a high-performance 3D printing part with few pores and good interphase, interline and interlayer combination is formed after repeated layer by layer printing. The method has the advantages of being high in material adaptability and wide in application prospects and the like.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a device and method for assisting 3D printing based on ultrasonic vibration. Background technique [0002] 3D printing technology, also known as additive manufacturing, is one of the important symbols of the third industrial revolution. Together with artificial intelligence and intelligent robots, it is called the three key technologies to promote the development of digital manufacturing. Compared with traditional subtractive manufacturing and equal-material manufacturing processes, 3D printing technology is widely used in aerospace, biomedical, transportation and other fields due to the advantages of moldless manufacturing and rapid overall prototyping. [0003] With the continuous development of China's manufacturing industry, the performance requirements of parts are becoming more and more stringent. It is difficult to obtain isotropic parts by adding materials layer by laye...
