Abstract
A manufacturing method comprising the steps of forming at first solidified wax layer of a desired shape, depositing onto the first solidified wax layer at least one layer of a liquid resin formulation, solidifying the layer of liquid resin formulation, depositing a second wax layer on to the combination of the first solidified wax layer and the layer of solidified resin formulation, solidifying the second wax layer, and separating the solidified resin formulation from first and second wax layers. Preferably, the resin formulation comprises at least one monofunctional water soluble vinyl or acrylic monomer in combination with a low molecular weight aliphatic polymer having acrylic or methacrylic acid functionality. The solidified wax and resin formulation layers can be machined as may be desired to form mold of a given shape comprising wax layers when the layer of formulation is separated from the wax layers.
