Abstract
The present invention is directed to a three-dimensional printing system and method, and an article made therefrom. The method of the present invention includes building cross-sectional portions of a three dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas are built using an ink-jet printhead to deliver an aqueous fluid to a particle material that includes a first particulate material, a second particulate material, and a third particulate material, wherein the first and second particulate materials react in the presence of the fluid in a period of time, and the third particulate material reacts in the presence of the fluid to form a solid in a longer period of time.

55. A method of three-dimensional printing, comprising:
-
providing a layer of a dry particulate material comprising a first particulate material, a second particulate material, and a third particulate material;
dispensing a fluid onto a region of the first layer;
causing a reaction between the first and second particulate materials to occur, the reaction causing a solidified material to form in the region; and
causing the third particulate material to solidify in the region, wherein the reaction between the first and second particulate materials occurs in a period of time, and the third particulate material solidifies in a longer period of time. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83)

84. A mixture of solids used in three dimensional printing that, when contacted by a fluid, undergoes a first solidification reaction beginning with the fluid contact and occurring at a first rate, and also undergoes a second solidification reaction beginning with the fluid contact and occurring at a second rate slower than the first rate.
