(54) Title: METHODS FOR SHAPING GREEN BODIES AND ARTICLES MADE BY SUCH METHODS O (57) Abstract: A method of shaping a green body provides a shaped green body comprised of a plurality of sinterable particles and O an organic binder. Such a method includes: (1) molding a mixture of sinterable particles and organic binder into the shape of an initial green body or intermediate, wherein the sinterable particles include at least one of metal particles or ceramic particles; and (2) shaping the green body intermediate with at least one of a stream of energy or a stream of matter, wherein the shaping yields a green body having a desired shape. The shaped green body can be sintered in order to provide a hardened body having substantially the shape of the shaped green body. The process is especially useful for manufacturing orthodontic brackets.
