1. A method of creating additive manufactured parts, the method comprising:
selectively dispensing, in a shape area according to a layer of a part to be created by additive manufacturing, a second composition onto a top surface of a first composition in a vat, wherein polymerization components for formation of the layer are kept separate from each other until the dispensing, with at least one of the polymerization components being in the second composition; and
illuminating the top surface to expose the first composition and the second composition to light having a polymerization wavelength, thereby causing polymerization of the layer of the part only in the shape area;
wherein the dispensing comprises customizing a reaction variable of the polymerization to customize reaction kinetics in different portions of the shape area,
wherein the second composition has a second viscosity that is less than a first viscosity of the first composition.
