Title: MANUFACTURE OF THREE DIMENSIONAL OBJECTS FROM THERMOSETS
Abstract:
Provided herein is a method for creating a three dimensional (3D) object from reactive components that form a thermoset product. In one embodiment, a method includes providing first and second reactive components that are effective to form the thermoset product. In one embodiment, the thermoset product includes a urethane and/or urea-containing polymer. In one embodiment, the first reactive component includes an isocyanate and the second reactive component includes a polyol having at least one terminal hydroxyl group, a polyamine having at least one amine that includes an isocyanate reactive hydrogen, or a combination of the polyol and the polyamine. In one embodiment, the first reactive component includes a prepolymer, and optionally the ratio of viscosity of the first and second reactive components is from 1 :3 to 3 : 1. Also provided is a 3D object that includes a completely reacted thermoset product, and a thermoset system that includes a first and a second reactive component.
