3d printing method

The invention relates to a 3D printing method. The method comprises the steps that a 3D printer is connected; the type of the printing technology corresponding to the 3D printer is recognized; the specific type of the 3D printer is recognized; the design printing mode corresponding to the 3D printer is generated according to the recognized type of the printing technology and the recognized specific type; a three-dimensional model is obtained; and under the design printing mode, a printing file is generated according to the three-dimensional model. The 3D printing method is suitable for 3D printers of different types, the problem that in a traditional method, when a user needs to update 3D printers or needs to use different 3D printers for printing due to different printing object properties, corresponding design software needs to be designed and installed to finish printing is solved, the using cost is saved, and using is facilitated for the user.
