Methods for additive manufacturing

Abstract:

A method of additively manufacturing an obiect comprises transforming the resin of a feedstock line from a first at least partially uncured state to a rigid at least partially uncured state, introducing the feedstock line into a delivery guide with the resin of the feedstock line in the rigid at least partially uncured state, transforming the resin of the feedstock line from the rigid at least partially uncured state to a second at least partially 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 using the delivery guide, and transforming the resin of the feedstock line from the second at least partially uncured state to an at least partially cured state after the feedstock line is dispensed from the delivery guide along the print path.
