Abstract:
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.

Claim (Index 1):
A method of creating a three dimensional (3D) object from reactive components that form a thermoset product using extruded thermoset printing, comprising:\n providing a first reactive component and a second reactive component that are effective to form a thermoset product having a predetermined layer resolution during the method; introducing the first reactive component and the second reactive component into a mixing chamber where mixing occurs to form a mixture,\n wherein the first reactive component, the second reactive component, or the first reactive component and the second reactive component contains a fast reactant and a slow reactant, wherein the first reactive component, the second reactive component, or the first reactive component and the second reactive component contains 1% to 10% fast reactant and 1% to 75% slow reactant, \n wherein the first reactive component and the second reactive component have a residence time in the mixing chamber effective to form a partially reacted thermoset product in the mixing chamber and result in the predetermined layer resolution upon exiting the mixing chamber, and \n wherein the first reactive component and the second reactive component have a residence time in the mixing chamber insufficient to completely react; \n extruding the partially reacted thermoset product out of the mixing chamber through an extrusion nozzle and onto a substrate; and moving the extrusion nozzle and/or the substrate to form a 3D object having a predetermined shape resolution.
