Methods for additive manufacturing

Abstract:

A method of additively manufacturing an object comprises applying a resin in a first non-rigid uncured state to elongate fibers to create a feedstock line, transforming the resin of the feedstock line from the first non-rigid uncured state to a rigid uncured state, introducing the feedstock line into a delivery guide with the resin of the feedstock line in the rigid uncured state, transforming the resin of the feedstock line from the rigid uncured state to a second non-rigid uncured state as the feedstock line passes through the delivery guide or as the feedstock line exits the delivery guide, depositing the feedstock line along a print path, and at least partially curing the resin of the feedstock line after the feedstock line is deposited by the delivery guide along the print path.
