Abstract

The invention discloses a high-frequency vibration 3D printing nozzle which can be used for improving the interlayer bonding degree of an FDM printed part and enhancing the mechanical property of the part. The device is characterized by comprising a vibration mechanism, a transmission mechanism and a melt extrusion mechanism, the vibration mechanism comprises a piezoelectric actuator and a micro-displacement amplification mechanism, the vibration mechanism is connected with the melt extrusion mechanism through a load connecting block, and the effect of vibrating the spray head is achieved through high-frequency vibration of the piezoelectric actuator and displacement amplification of the micro-displacement amplification mechanism; the transmission mechanism transmits the rotation of the extrusion motor to the extrusion wheel so as to convey consumables to the melt extrusion mechanism; and the melt extrusion mechanism is used for melting and extruding the consumables. The device is simple in structure, and the interlayer bonding degree of a printed piece is improved through high-frequency vibration, so that the mechanical property of the printed piece is enhanced.

Description

technical field [0001] The invention relates to the field of FDM3D printers, in particular to a high-frequency vibration 3D printing nozzle. 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] Among them, FDM3D printing technology, due to its low price, high printing speed, small impact on the environment, low technical difficulty, simple structure, low maintenance cost, high utilization rate of original consumables, high print strength, and ...
