23 Jul Pneumatic extrusion sprayer biological 3D printing molding system for manufacturing skin tissues and molding method
Abstract
The invention relates to a pneumatic extrusion sprayer biological 3D printing molding system for manufacturing skin tissues and a molding method, and belongs to the technical field of tissue engineering technologies and biological 3D printing. The pneumatic extrusion sprayer biological 3D printing molding system comprises a base plate and a control system composed of a computer and a controller; the pneumatic extrusion sprayer biological 3D printing molding system is characterized in that the molding system is composed of a sprayer device, a three-dimensional motion mechanism and a molding table; the pneumatic extrusion sprayer biological 3D printing molding system is novel in structure, clear in working principle, a Y shaft is controlled by double motors, and therefore the accuracy of space motion of the sprayer is guaranteed; the molding table is fixedly installed on the base plate, and therefore alignment arrangement of the sprayer of a printing machine during printing each time is avoided; and due to the fact that a pressure system formed by compression gas has the beneficial effects of final motion, high flexibility, easy control and the like, the pressure approximating to static pressure can be provided for meeting the pneumatic erupting technology requirement, and the mechanical property and the architectural feature of the support tissues can be provided for meeting certain specific requirements of the human body.
