3D bioprinting system

Abstract

The invention provides a 3D bioprinting system. The 3D bioprinting system comprises a control assembly, a motion assembly, a rotating assembly, an air pump assembly, a temperature adjusting assembly and a jetting assembly; the control assembly comprises a material output control module, a motion control module, and a temperature control module, the motion control module controls the rotating assembly and the jetting assembly to move through the motion assembly, the material output control module controls the jetting assembly to jet the material to a rotating rod of the rotating assembly through the air pump assembly, the temperature control module adjusts the jetting temperature of the jetting assembly and the temperature of the rotating rod through the temperature adjusting assembly, in the rotating process of the rotating rod of the rotating assembly, the jetting assembly is controlled to jet or extrude the material to the rotating rod, and rotary printing of the biological product can be achieved; through supporting of the biological product with the rotating rod as the hollow structure, an extra supporting material is not needed, and the material cost and the economic cost areeffectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D bioprinting system. Background technique [0002] 3D bioprinting is based on the computer three-dimensional model, through the method of software layered discrete and numerical control molding, positioning and assembling biomaterials or living cells, and manufacturing biomedical products such as artificial implant scaffolds, tissues and organs, and medical assistance. [0003] When the 3D bioprinter is started, the computer modeling program will design the cross-section of the organ to be printed to accurately guide the subsequent printing process; then the "toner" will be gathered on the pre-designed biocompatible material through the printing head According to a certain pattern, the prototype of the printed organ is gradually formed, and the living tissue is constructed. [0004] However, the above-mentioned traditional 3D bioprinting is to pile up biological mate...

Problems solved by technology

[0004] However, the above-mentioned traditional 3D bioprinting is to pile up biological materials on a plane to form human organs or medical scaffolds. However, there are many tubular organs in the human body such as blood vessels and intestines. If traditional printing methods are used, it will be wasteful. A large amount of support material increases the economic cost
