A manufacturing platform system for 3D blood vessel printing

Abstract

The invention discloses a manufacturing platform system for 3D biological blood vessel printing, aiming to solve the problem that the current 3D blood vessel printing lacks a corresponding printing system platform. The platform uses linear motors and rotary motors as its power system to build a five-axis motion system. Add a double mover on the X axis to drive two Z axes to move, and install the print head on the Z axis, and drive the print head to move up and down in space through the Z axis. Add a rotation axis C-axis on the Y-axis, as a blood vessel printing platform. In actual printing, the double Z-axis drives two printing nozzles to move relative to the rotation axis C-axis in space, and cooperates with the rotation axis to perform multi-nozzle printing, which improves the printing accuracy and meets the 3D printing requirements of blood vessels.

Description

technical field [0001] The invention relates to a manufacturing platform system, in particular to a multi-dimensional motion manufacturing platform system for 3D biological blood vessel printing. Background technique [0002] In recent years, organ transplantation technology has developed by leaps and bounds, but at the same time, it also faces problems such as insufficient organ sources. Therefore, many studies are currently looking for new technologies to replace living organs, and 3D bioprinting technology is the main trend of current development. [0003] Vascular diseases are one of the most important problems of human diseases and pose a great danger to human health. The report shows that the number of cardiovascular disease patients in my country reached 290 million in 2012, and about 3.5 million people died of cardiovascular disease every year, accounting for 41% of the total cause of death, ranking first among various diseases. At present, the commonly used method...

AI Technical Summary

Problems solved by technology

At present, the commonly used method to solve vascular diseases is blood vessel replacement and transplantation. Due to the lack of living blood vessels, artificial biomaterial blood vessels are generally used as replacements. The existing problems are human rejection and bacterial infection.

[0004] At present, there is no manufacturing platform system for 3D blood vessel printing. The main platform system is an ordinary three-dimensional motion platform, which is generally designed with an ordinary servo motor, which cannot meet the 3D printing requirements for blood vessels in terms of accuracy and design requirements.
