Method for free-formation of a free-standing, three-dimensional body
First Claim
1. A method for a free-form preparation of a free-standing three-dimensional structural body by successively generating adjacent cross-section layers of the body with a freshly generated layer generated on top of a previously generated layer and with previously and freshly generated adjacent layers integrated to comprise the free-standing three-dimensional structural body, which method comprises:
- successively repeating the steps of;
a) placing a plurality of individual liquid drops of a liquid composition on a support surface as discrete individual drops arranged in a pattern corresponding to a cross-sectional layer of the body being prepared and positioned within the pattern so as to be non-contacting, and with the liquid composition containing a first reactant;
b) placing a plurality of discrete individual liquid drops of an other liquid composition in said pattern of the cross-sectional layer of the body being prepared with the depositing of the discrete individual drops of the other liquid composition positioned within said pattern so as to contact and connect non-contacting deposited drops of the liquid composition, and with the other liquid composition containing an other reactant adapted after contacting the first reactant to chemically react therewith to form a solid which comprises the cross-sectional layer of the body being prepared.

Abstract
A preparing of a self-supporting or free-standing three-dimensional unitary structural body by a method including generating successively a plurality of cross-sectional layers of the body, one layer top of the other and with the layers joined together to form the body and with the generating of a cross-sectional layer comprising placing a plurality of drops of a liquid composition, containing a first reactant, in a pattern of discrete drops making up the cross-sectional layer and subsequently placing a plurality of discrete drops of other liquid composition, containing another reactant, in contact with the placed drops ion the pattern so that the first reactant and the other reactant react to provide a solid.

A method for a free-form preparation of a free-standing three-dimensional structural body by successively generating adjacent cross-section layers of the body with a freshly generated layer generated on top of a previously generated layer and with previously and freshly generated adjacent layers integrated to comprise the free-standing three-dimensional structural body, which method comprises:
- successively repeating the steps of;
a) placing a plurality of individual liquid drops of a liquid aqueous composition on a support surface as discrete individual drops arranged in a pattern corresponding to a cross-sectional layer of the body being prepared and positioned within the pattern so as to be non-contacting, and with the liquid aqueous composition containing a first reactant; b) placing a plurality of discrete individual liquid drops of an other liquid aqueous composition in said pattern of the cross-sectional layer of the body being prepared with the depositing of the discrete individual drops of the other liquid aqueous composition positioned within said pattern so as to contact and connect one or more non-contacting deposited drops of the liquid aqueous composition, and with the other liquid aqueous composition containing an other reactant adapted after contacting the first reactant to chemically react to form an inorganic solid which comprises the cross-sectional layer of the body being prepared. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
