Abstract
The present disclosure provides a bioprinter spray head assembly and a bioprinter, wherein the spray head assembly is internally provided with a first flow channel and a second flow channel, an outlet of the first flow channel is adjacent to an outlet of the second flow channel, and the outlet of the second flow channel is configured to make a second material sprayed therefrom move towards a first material out of the outlet of the first flow channel, such that the second material sprayed from the outlet of the second flow channel and the first material sprayed from the outlet of the first flow channel are combined together to form a fluid printing unit. The bioprinter spray head assembly can guide the auxiliary materials to wrap the cells for protection, thereby reducing the cell damage caused by the extrusion pressure and the frictional force subjected in the printing process, so as to improve the survival rate of the cells and present a high reliability.
