Abstract
A method of forming a three-dimensional object, wherein said three-dimensional object is a footwear sole, heel, innersole or midsole, is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.
