Abstract

A recyclable mold for casting a metal article or forming a metal or ceramic article by injection molding is disclosed. The recyclable mold comprises base material particles mixed with a binder material binding the base material particles to define a predetermined shape having a cavity in which the metal article is to be cast. The injection molded metal or ceramic part comprises mixing fusable metal or ceramic powder with a binder material to form a solidified green body. The binder material is soluble in carbon dioxide and comprises a tert-butyl ated aromatic or sugar acetate.
