Background

The 3D printing technology is characterized in that a computer three-dimensional design model is used as a blueprint, special materials such as metal powder, ceramic powder, plastics, cell tissues and the like are stacked layer by layer and bonded through a software layering dispersion and numerical control forming system in a laser beam mode, a hot melting nozzle mode and the like, and finally, solid products are manufactured through stacking forming. The common 3D printing technology is a fuse deposition technology, which heats and melts a filamentous hot melt material, extrudes the material through a nozzle with a fine channel, deposits the material on a worktable after being ejected from a nozzle, starts to solidify after the temperature is lower than the solidification temperature, and finally forms a finished product through layer-by-layer stacking of the material. Wherein, the heating body for heating and melting the thread-shaped hot melt material is a core component. In the past, the heating body of the 3D printer is large in size, the whole movement is not stable during operation, the heating area is small in occupied ratio, the whole temperature is unstable, and the precision of a 3D printed product is low.
