Problems solved by technology

The current bio-3D printers are limited by the structure and materials. Most of them realize bioprinting by modifying the nozzle on the basis of the structure of ordinary 3D printers. Stacked layer by layer, the printed objects have certain deficiencies in biological anisotropy and biological activity retention, and the scope of use is limited

Abstract

The invention relates to a multi-arm cooperation type biological three-dimensional printing device comprising spray nozzle joint modules, elbow joint modules, base joint modules, rotation joint modules and accessories. Each module comprises a motor drive unit, a limiting switch, a brake and connection pieces of the motor drive unit, the limiting switch and the brake. Each spray nozzle joint modulecomprises a spray nozzle fixture block and a spray nozzle. The elbow joint modules and the base joint modules each comprise a synchronous belt transmission mechanism, a tensioning mechanism and a speed reduction unit. Each rotation joint module comprises a circumference guide rail, a supporting base, rail rolling wheels, a bearing plate, a transmission gear, a motor control unit and a lubricationdevice. According to the multi-arm cooperation type biological three-dimensional printing device, on the basis of a double-parallelogram serial mechanism, oriented printing achieved through multi-mechanical-arm cooperation for multiple points within the space range is achieved; the tail end posture of the mechanical arm cannot change along with changes of angles of elbow joints and base joints; different materials can be selected according to target types for printing of biomedical engineering products such as artificial implants and intervention bodies; and the application range is wide.

Description

technical field [0001] The invention relates to a biological three-dimensional printing mechanism, in particular to a multi-arm cooperative biological three-dimensional printing device. Background technique [0002] 3D printing technology is a rapid prototyping technology driven by digital models to rapidly manufacture three-dimensional physical entities of any complex shape. With the development of materials and control technology, people's demand for biologically active artificial organs, implants and personalized medicine has increased. Forefront. The current bio-3D printers are limited by the structure and materials. Most of them realize bioprinting by modifying the nozzle on the basis of the structure of ordinary 3D printers. Stacked layer by layer, the printed objects have certain deficiencies in biological anisotropy and biological activity retention, and the scope of use is limited. [0003] On the basis of the patent China 201810583394.6: an intelligent multi-sou...
