An additive manufacturing system is disclosed for use in discharging a continuous reinforcement. The additive manufacturing system may include a support, and a compactor operatively connected to and movable by the support. The compactor may be configured to apply a pressure to the continuous reinforcement during discharge. The additive manufacturing system may also include a feed roller biased toward the compactor to sandwich the continuous reinforcement between the roller and the compactor, and a cutting mechanism at least partially recessed within at least one of the feed roller and the compactor. The cutting mechanism may be configured to selectively move radially outward to engage the continuous reinforcement.

A light-based measurement system is capable of directing a light beam to a cooperative target used in conjunction with a cable robot to accurately control the position of the end effector within a large volume working environment defined by a single coordinate system. By measuring the end effector while the device is in operation, the cable robot control system can be adjusted in real time to correct for errors that are introduced through the design of the robot itself providing accuracy in the tens or hundreds of micron range. A coordination processor runs control software that communicates with both the laser tracker and the cable robot. An action plan file is loaded by the software that defines the coordinate system of the working volume, the locations where actions need to be performed by the cable robot, and the actions to be taken.
