Abstract

A three-dimensional object is fabricated from powder. A powder layer is deposited. The powder layer is selectively wetted to hinder movement of the powder. A binder is applied to selected areas of the powder layer to harden the areas of the powder layer. The steps are repeated until the three-dimensional object is fabricated.
