Abstract
A water-soluble thermoplastic composition for three-dimensional modeling comprising poly(2-ethyl-2-oxazoline) is disclosed. The composition in the form of an extrudable object may be extruded by an extrusion apparatus in a programmed pattern onto a base as a ribbon of liquified polymer to create a support structure for a prototype object or to create a water-soluble polymeric element.
