Abstract
A method for producing an article and a system associated with the method are provided. The method includes providing a green part, cooling the green part to a temperature below the freezing point of the ink to form a hardened mass and loosely-attached powder particles, and removing the loosely-attached powder particles. The green part includes powder particles, an ink, and optionally a binder. The loosely-attached powder particles removed from the green part may be recycled and reused.
