Zusammenfassung:	The application relates to a method for preparing a 3D printing gradient antibacterial film, a product and application thereof, which belongs to the field of microbes. The method comprises the following steps: taking alginic acid and pectin, adding glycerol 5 and distilled water, and performing uniform stirring to obtain several groups of mixed solution I; taking and dissolving chitosan into acetic acid solution to obtain several groups of mixed solution II with gradient concentration; correspondingly adding the several groups of mixed solution II with gradient concentration into the several groups of mixed solution I one to one, and performing uniform stirring to form a colloidal 10 state to obtain several groups of 3D printing raw materials; respectively performing 3D printing by using the several groups of 3D printing raw materials to obtain several films, and sequentially splicing the several films together seamlessly according to the mass fraction of chitosan; soaking the film in CaCl 2, and performing drying to obtain a 3D printing gradient antibacterial film. The 3D printing gradient antibacterial film 15 provided by the application can be used to observe the movement trajectories of microbial strains.
