Integrated biological 3D printer printing cavity body environment control system and control method

Abstract

The invention provides an integrated biological 3D printer printing cavity body environment control system and a control method. The system comprises a control module, a ventilating module, a high-efficiency filtering module, a condensing and dehumidifying module, a heating and humidifying module and an air distributing module, wherein the ventilating module, the high-efficiency filtering module,the condensing and dehumidifying module, the heating and humidifying module and the air distributing module are sequentially connected; the air distributing module is arranged at the top of a biological 3D printer printing cavity body, the ventilating module is communicated with the inside of the printing cavity body and the outside of a biological 3D printer, and the ventilating module, the high-efficiency filtering module, the condensing and dehumidifying module, the heating and humidifying module and the air distributing module are all connected with the control module. The system disclosedby the invention can achieve integrated control on temperature, humidity, aseptic environment, air speed, air volume and wind direction in the biological 3D printer printing cavity body; furthermore,the environment in the printing cavity body is kept in a stable state, and a high-accuracy biological 3D printing requirement can be met.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, and more specifically, relates to an environment control system and control method for an integrated biological 3D printer printing cavity. Background technique [0002] 3D printer is the key equipment to realize biological 3D printing technology, and its environmental control must be very precise to obtain a sterile and stable environment. The controlled environment of the 3D printer needs to meet the molding requirements and precision requirements of biological 3D printing to ensure the smooth progress of molding and the survival and growth of cells. [0003] At present, there are two main ways to control the printing environment of bioprinters. The first is to put the bioprinter into a biosafety cabinet or ultra-clean bench to obtain a sterile operating environment. The advantage of this method is that the bioprinter does not need its own environmental control, and a near-sterile...

Problems solved by technology

The advantage of this method is that the bioprinter does not need its own environmental control, and a near-sterile environment can be obtained from a biological safety cabinet or ultra-clean table, and it can be conveniently operated during the printing process without destroying the near-sterile environment; but The disadvantage is that the temperature, humidity, air volume, and wind speed in the printing environment cannot be adjusted separately, which will affect the printing process

The second is that the biological 3D printer has its own environmental control module, such as temperature control, humidity control, ultraviolet light sterilization, etc. The advantage of this method is that the controlled cavity environment can be obtained on only one device, which can Printing requires individual adjustment of each parameter to obtain a suitable printing environment; but the disadvantage is that this method can hardly be operated during the printing process, otherwise the controlled environment will be destroyed, and the stability of the controlled environment is poor

At the same time, the above environmental control methods do not adjust the airflow direction and wind speed in the cavity environment
