A 3D printing method implemented by movable platform is disclosed. When printing a printing layer, a 3D printer first calculates respectively a starting point and an ending point of each swath of the printing layer, and calculates movement information of a movable printing platform upon an X-axis and a Y-axis of the 3D printer according to the starting points and the ending points. Next, the 3D printer controls the printing platform to move along the X-axis and the Y-axis based on the movement information, and controls a nozzle of the 3D printer to jet ink while the printing platform moves to corresponding positions. Therefore, the 3D printer uses the printing platform to complete printing actions of each swath.
