1. An additive manufacturing system, comprising:
a support;
a print head operatively connected to and moveable by the support, the print head including:
a first supply configured to hold a continuous reinforcement;
a second supply configured to hold a matrix separate from the continuous reinforcement; and
a wetting mechanism in separate communication with the first and second supplies and configured to discharge the continuous reinforcement wetted with the matrix; and
a controller programmed to selectively pressurize the second supply to direct the matrix to the wetting mechanism, wherein:
the second supply is configured to receive a cartridge containing the matrix;
the cartridge includes a piston moved by the controller to push matrix out of the second supply; and
the controller is programmed to selectively communicate a pressurized medium with the piston to selectively pressurize the second supply.
