Abstract
The invention discloses multi-spray head biological 3D printing equipment capable of batching and mixing materials automatically and a control method for the multi-spray head biological 3D printing equipment, and belongs to the field of tissue engineering and biological 3D printing. Pneumatic supplies of pneumatic material pressing tanks are connected with the inlets of solenoid directional valves; the outlets of the solenoid directional valves are connected with spray heads; when the pneumatic supplies supply pressure and the solenoid directional valves are electrified, biological materials in the pneumatic material pressing tanks can be pressed into a material mixing cylinder in proportions, and are mixed uniformly through a stirrer in a material mixing tank assembly. The material mixing tank assembly is connected with the pneumatic supplies and the inlets of the solenoid directional valves; the outlets of the solenoid directional valves are connected with the spray heads; when the pneumatic supplies supply the pressure and the solenoid directional valves are electrified, the biological materials in the pneumatic material pressing tanks can be pressed out from the spray heads; and the spray heads complete printing work according to a preset route under the cooperated movement of a moving top beam and a material taking driving arm. The multi-spray head biological 3D printing equipment capable of batching and mixing the materials automatically and the control method for the multi-spray head biological 3D printing equipment have the advantages that the materials can be batched and mixed quickly and automatically; multiple printing requirements can be met by the spray heads; printing performance can be played better; flexible control is easy to realize; the printing efficiency is improved.
