1. A method for solid free-form fabrication of a three-dimensional metal object, comprising:
- depositing a particulate blend in a defined region, said particulate blend including a number of metal or metal alloy particulates and a peroxide; and
selectively ink-jetting a binder system onto a predetermined area of said particulate blend to form a green part, wherein said binder system includes a water soluble monofunctional acrylate-based monomer, a water soluble difunctional acrylate-based monomer, an amine, and water.
