Bio-printing device and bio-printing method thereof

Abstract

The invention provides a bio-printing device and a bio-printing method thereof, solves the problem that the existing bio-gel printing technology cannot ensure stable capture so as not to ensure the acquisition of accurate structural arrangement of biological inclusions such as cells in bio-gel, and belongs to the field of intelligent bio-manufacturing. The biological printing device provided by the invention comprises a printing working chamber, a photocuring module and acoustic tweezers, the printing working chamber is used for accommodating a photo-curing gel cell suspension; the acoustic tweezers are used for generating an acoustic surface wave sound field to act on the photocuring gel cell suspension; the light curing module is used for emitting light to the printing work cavity so as to act on the light curing gel cell suspension. In the application, after the cells of the photo-curing gel cell suspension complete cell pattern arrangement through the acoustic surface wave sound field generated by the acoustic tweezers, the cell patterns are cured through the photo-curing module, so that the arrangement of the cells in the biological printing structure and the external structure are regulated and controlled at the same time.
