Problems solved by technology

[0004] In the process of 3D printing of hydrogel materials, the normal output of the nozzle is a very important link to ensure the printing quality. If the output is not normal, the nozzle will be blocked, and the nozzle will easily form swelling droplets. If the supply is not repaired in time Adjusting the material mechanism will seriously affect the printing quality, and even cause printing failure
