Patent number: 10112346Abstract: A printing method using a low melting-point material is disclosed. The method first controls a nozzle of a 3D printer to move to a position corresponding to an internal-contour of a 3D model for printing the internal-contour upon a printing platform, then controls the nozzle to move to other position corresponding to an exterior-contour of the 3D model for printing the exterior-contour.
