Biological 3D printing device suitable for multiple materials of gradient structure

Abstract

The invention discloses a biological 3D printing device suitable for multiple materials of a gradient structure and belongs to the field of medical instrument quick manufacturing and molding. According to the biological 3D printing device, mechanical arm 3D motion units are arranged in a thermotank and used for driving spray heads to do X, Y and Z-direction 3D motion in biological fluid on the upper portion of the interior of a forming box to conduct biological 3D printing; a hydraulic unit is arranged in the thermotank; an inlet pipe communicates with a hydraulic pump and the bottom of the forming box, and an outlet pipe extends in conformance to the mechanical arm 3D motion units and communicates with the hydraulic pump and the spray heads; the biological liquid at the bottom of the forming box is pumped to the spray heads through the hydraulic pump; a sensor and assistance unit is used for monitoring and adjusting the internal environment of the thermotank; a control and data processing unit is used for controlling operation of the mechanical arm 3D motion units and the hydraulic unit and receiving and processing monitoring data provided by the sensor and assistance unit. The biological 3D printing device has the advantages of high automation degree, greenness, low carbon, high efficiency and wide effective utilization space and has important significance on achievement of control over the temperature gradient of a biological material.

Description

technical field [0001] The invention belongs to the field of rapid manufacturing of medical devices, and more specifically, relates to a new bio-3D printing comprehensive molding system that uses multi-manipulators to support multi-nozzle movement and hydraulic pump technology to provide biological fluids, and is suitable for bio-3D printing with gradient structures and multi-materials Research. Background technique [0002] Traditional biological 3D printers rely too much on long-distance linear moving parts such as lead screws, optical axes, and linear guides, which restricts the printing space in the effective forming area and has a low degree of automation; conventional biological 3D printing nozzles adopt a syringe-type structure, and the volume of the syringe is limited The one-time molding rate of large-sized biological structural parts is reduced, and the efficiency is low, and the working environment is not easy to control, which affects the survival rate of biologi...
