摘要： A method for detecting object border of 3D printer (4) includes following steps: obtaining a basic locating point (420) of a printing platform (42) of the 3D printer (4); projecting an imported 3D object onto a 2D plane of the 3D printer (4) for obtaining a plurality of 2D coordinates of the 3D object; calculating a 2D convex hull (60) according to the plurality of 2D coordinates; obtaining all vertexes (601) of the 2D convex hull (60); determining the position of the 3D object based on the basic locating point (420) in company with all the vertexes (601) of the 2D convex hull (60); and, permitting the 3D printer (4) to activate a printing procedure only if the 3D object is determined fully locating inside an effective range of the printing platform (42).
