Claim 17:
18. A method comprising:
fabricating, from a first material, a support structure for an object;
fabricating a weak connection interface layer adjacent to the support structure; and fabricating a surface of the object from a second material, the surface of the object adjacent to the interface layer and the second material including a powdered material for forming a final part and a binder system including one or more binders, wherein the one or more binders retain a net shape of the object during processing of the object into the final part, wherein processing of the object into the final part includes debinding the net shape to remove at least a portion of the one or more binders and sintering the net shape to join and densify the powdered material, and wherein the interface layer weakly connects the support structure to the object during sintering;
and wherein the support structure is subject to drag on a furnace floor that, absent the presence of the support structure, the shape of the three-dimensional object would be subject to during the step of sintering.
