Ultrasonic-assisted vibration FDM type 3D printing platform

The invention discloses an ultrasonic-assisted vibration FDM type 3D printing platform which comprises a hot bed arranged on a supporting plate. Ultrasonic transducers are fixed to the lower portion of the supporting plate. The ultrasonic-assisted vibration FDM type 3D printing platform is used for making the hot bed generate ultrasonic vibration during 3D printing, and the ultrasonic transducers are fixed to a fixing plate through flanges on amplitude changing poles. By means of the above ultrasonic-assisted vibration FDM type 3D printing platform, the microwave-shaped microscopic structure of a printing product can be improved, the mechanical performance is higher, combination of printing layers is more compact, and the surface roughness of the printing products is lowered.
