The invention discloses an outer wall speed adjusting method, system and device for 3D printing and a medium, and the method comprises the steps: obtaining model data of an object, and carrying out the slicing and path planning of the model data through employing slicing software, and obtaining a G code source file; the G code source file is read, different printing layers are identified according to identification heads, the outer wall speed in each printing layer is obtained, and the numerical value of the outer wall speed is modified and stored; and traversing all printing layers in the G code source file to obtain a new G code source file. According to the method, according to the self-adaptive printing speed value of each layer, the printing speed can be regulated and controlled by modifying the relevant speed parameters of the 3D printing G code file exported by replacing the slices, so that the requirements of workpiece printing precision and efficiency are met. The method can be widely applied to the
