Abstract

The present disclosure provides a method for building a three-dimensional object using a printable composition including high viscosity polymerizable components. The method includes the steps of a) providing a printable composition comprising a high viscosity polymerizable component and a temporary solvent; b) selectively curing the printable composition to form an article representing the shape of the three-dimensional object; and c) removing a substantial amount of the temporary solvent from the article. The method is particularly well suited to making an orthodontic clear tray aligner. Also disclosed are a variety of printable compositions including high viscosity polymerizable components, such as polyurethane methacrylates, and temporary solvents.
