A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include a first supply configured to hold a liquid matrix, a second supply configured to hold a continuous reinforcement, and a wetting module configured to separately receive the liquid matrix and the continuous reinforcement from the first and second supplies, respectively, and to discharge a composite material including the continuous reinforcement wetted with the liquid matrix. The wetting module may include a body forming an internal chamber having an upstream open end and a downstream open end, an entrant nozzle disposed within the upstream open end and configured to receive the continuous reinforcement, and an exit nozzle disposed within the downstream closed end and configured to discharge the composite material.

Print head for additive manufacturing system

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include an outlet configured to discharge a material in a trajectory along a central axis of the outlet, and a compactor disposed downstream of the outlet relative to the trajectory and configured to press the material transversely against an adjacent surface. The outlet may be configured to translate relative to the compacting module.

The print head may include an outlet configured to discharge a material in a trajectory along a central axis of the outlet; a compactor disposed downstream of the outlet relative to the trajectory and configured to press the material transversely against an adjacent surface, and a cutting module located between the outlet and the compactor. The compactor and the cutting module may be configured to move together relative to the outlet.

Print heads for additive manufacturing systems

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include 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. The system may also include a controller programmed to selectively pressurize the second supply to direct the matrix to the wetting mechanism.

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head connected to and moveable by the support. The print head may have an outlet configured to discharge a continuous reinforcement at least partially coated in a matrix, and a device located inside the print head and configured to at least partially coat the continuous reinforcement with the matrix. The system may also include a sensor configured to generate a signal indicative of an amount of the matrix, and a controller in communication with the sensor and the device. The controller may be configured to direct a command to the device to cause the device to advance matrix toward the continuous reinforcement during passage of the continuous reinforcement through the print head, and to selectively adjust the command based on the signal.

System for additive manufacturing

A system is disclosed for additively manufacturing an object. The system may include a support, and a print head having an outlet and being connected to and moveable by the support in a normal travel direction during discharge of material from the print head. The system may also include a first device operatively connected to the print head at a trailing location relative to the normal travel direction. The first device may be configured to expose the material to a cure energy. The system may further have a second device operatively connected to the print head at a location trailing the first device relative to the travel direction. The second trailing device configured to expose the material to a cure energy.

System for additively manufacturing composite structures

A method is disclosed for additively manufacturing an object. The method may include discharging a composite material from a print head to form the object. The method may also include drawing out fewer than all components of the composite material from the print head prior to discharging.

A head is disclosed for an additive manufacturing system. The head may include a first outlet configured to discharge a composite material to form an object. The head may also include a second outlet located upstream of the first outlet and configured to discharge fewer than all components of the composite material.

A compactor is disclosed for use with an additive manufacturing print head. The compactor may include a housing connectable to the additive manufacturing print head. The compactor may also include a compacting wheel, and at least one spring disposed in the housing and configured to exert an axial force on the compacting wheel. The compactor may further include a piston moveable to adjust a distance between the housing and the compacting wheel.

System, print head, and compactor for continuously manufacturing composite structure

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include a supply of continuous reinforcement, an outlet configured to discharge the continuous reinforcement, and a tensioning module disposed between the supply and outlet. The tensioning module may be configured to generate a signal indicative of a tension in the continuous reinforcement. The system may also include a processor programmed to selectively cause the supply to dispense the continuous reinforcement based on the signal.

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head connected to and moveable by the support. The system may also include an encoder configured to generate a signal indicative of an amount of material passing through the print head, and a controller in communication with the encoder. The controller may be configured to selectively implement a corrective action in response to the signal.

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head connected to and moveable by the support. The print head may have an outlet configured to discharge a continuous reinforcement at least partially coated in a matrix. The system may also include at least one doser located inside the print head and configured to at least partially coat the continuous reinforcement with the matrix, a sensor located downstream of the at least one doser and configured to generate a signal indicative of an amount of matrix coating the continuous reinforcement, and a controller in communication with the sensor and the at least one doser. The controller may be configured to direct a feedforward command to the at least one doser to cause the at least one doser to advance matrix toward the continuous reinforcement during passage of the continuous reinforcement through the print head, and to selectively adjust the feedforward command based on the signal.
