1. A method of making a composite part, the method comprising:
additively manufacturing or extruding a polymer composition to form a tool, the polymer composition comprising a polymer matrix and a negative thermal expansion (NTE) additive;
applying a composite part composition or composite part laminate on or to the tool; and
exposing the tool to sufficient heat to cure the composite part composition or composite part laminate,
wherein the polymer composition further comprises a magnetically receptive additive, and
wherein the magnetically receptive additive comprises a substrate coated with a magnetically receptive coating material.
