Abstract
Disclosed is a method of forming a structured sintered article including providing a mixture comprising a sinterable particulate material and a binder, the binder comprising, as a function of total resin content of the binder, at least 50% by weight of a thermoplastic binder material and at least 5% by weight of a radiation-curable binder material; shaping the mixture with a mold to form a structure; setting the structure by cooling the structure or by allowing the structure to cool; separating the structure from the mold; irradiating the structure so as to at least partially cure the radiation-curable binder material, and debinding and sintering the structure so as to form a structured sintered article. Shaping may include forming a structure having one or more open channels, and sintering may include sintering in together in contact with at least one additional structure so as to cover or enclose the channels.
