The present invention is directed to a three-dimensional printing system and method, and an article (38) 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 (28) to deliver an aqueous fluid (26) 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.
La présente invention concerne un système et un procédé d'impression tridimensionnelle, ainsi qu'un article (38) produit au moyen de ce système et par ce procédé. Le procédé selon l'invention consiste à produire des sections d'un article tridimensionnel, puis à assembler les sections individuelles en couches de façon à former un article final. Les sections individuelles sont produites au moyen d'une tête d'impression à jet d'encre (28) destinée à projeter un fluide aqueux (26) sur un matériau à base de particules comprenant un premier matériau particulaire, un deuxième matériau particulaire et un troisième matériau particulaire, le premier et le deuxième matériau particulaire réagissant en présence du fluide en un certain temps et le troisième matériau particulaire réagissant en présence du fluide pour former un solide en un temps plus long.
