Abstract
Systems and methods for additively manufacturing composite parts are disclosed. Methods comprise combining a plurality of pre-consolidated tows to define a macro tow and dispensing the macro tow in three dimensions to define the composite part. Each pre-consolidated tow comprises a fiber tow within a non-liquid binding matrix. The combining comprises actively altering a shape and/or size of a cross-sectional profile of the macro tow along a length of the macro tow as it is being defined.
