Systems and methods for controlling additive manufacturing

A system for additively manufacturing a structure, comprising:

• an additive manufacturing machine;
• a peripheral device for determining a composition characteristic of a point to be used as an anchor by the additive manufacturing machine;
• a memory having computer-executable instructions stored thereon;
• and
• a processor configured to execute the computer-executable instructions to:
• selectively cause the additive manufacturing machine to discharge a path of composite material with a first ratio of matrix-to-fiber at the point to be used as an anchor by the additive manufacturing machine, when the composition characteristic is indicative of material at the point being previously discharged by the additive manufacturing machine;
• and
• selectively cause the additive manufacturing machine to discharge a path of composite material with a second ratio of matrix-to-fiber at the point, when the composition characteristic is indicative of material at the point being another material.
