Abstract
A computer-controlled method for forming a composition-controlled product using 3D printing includes disposing two or more liquid reactant compositions in respective two or more reservoirs; and mixing the two or more liquid reactant compositions, which in turn includes controlling by the computer a mass ratio of the mixed two or more liquid reactant compositions. The computer-controlled method further includes scanning, under control of the computer, a mixed liquid reactants nozzle over a substrate; depositing the mixed liquid reactant compositions onto the substrate; and operating, under control of the computer, a light source to polymerize the deposited mixed liquid reactant compositions.

A computer-controlled method for forming a composition-controlled product using 3D printing, comprising:
- disposing two or more liquid reactant compositions in respective two or more reservoirs;
- mixing the two or more liquid reactant compositions, comprising controlling by the computer a mass ratio of the mixed two or more liquid reactant compositions;
- scanning, under control of the computer, a mixed liquid reactants nozzle over a substrate;
- depositing the mixed liquid reactant compositions onto the substrate;
- and
- operating, under control of the computer, a light source to polymerize the deposited mixed liquid reactant compositions, comprising, throughout the entire method for forming the composition-controlled product, as the deposited mixed liquid reactant compositions touch the substrate, operating the light source to rapidly polymerize the compositions.
A method for composition-controlled printing of a 3D object, comprising:
- disposing each of a plurality of different liquid reactant compositions in respective ones of a plurality of reservoirs;
- controlling, by a computer, flows of the different liquid reactant compositions from the reservoirs into a mixing device, comprising:
- controlling, by the computer, a composition percentage of each of the different liquid reactant compositions in the mixing device comprising individually adjusting a flow from each of the respective ones of the reservoirs;
- mixing homogeneously, the different liquid reactant compositions in the mixing device;
- and
- controlling, by the computer, mechanical properties of the 3D printed object by a plurality of step-wise depositions and polymerizations of the homogeneously mixed liquid reactant compositions, comprising:
- depositing variable amounts of the homogeneously-mixed liquid reactant compositions onto a substrate using a scanning nozzle under control of the computer comprising controlling a flow from the mixing device, and
- polymerizing the deposited variable amounts of the homogeneously mixed liquid reactant compositions using a light source under control of the computer comprising throughout the composition-controlled product method as the deposited mixed liquid reactant compositions touch the substrate, operating the light source to rapidly polymerize the compositions.
