摘要： 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.

摘要： A method is disclosed for severing a continuous reinforcement from a print head at conclusion of an event during fabrication of a composite structure. The method may include moving the print head a distance away from the composite structure that provides clearance for a cutting mechanism between an outlet of the print head and the composite structure, and responsively causing the cutting mechanism to make a first cut of the continuous reinforcement at a boundary of the composite structure. The method may also include moving the print head to a waste discard location, and responsively causing the cutting mechanism to make a second cut of the continuous reinforcement at a desired distance offset from the outlet of the print head.

摘要： 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 in multiple dimensions. The system may also include a cure enhancer mounted to the print head and configured to expose composite material discharging from the print head to energy, and a curing tool mounted to the print head downstream of the cure enhancer. The curing tool may be configured to expose the composite material to additional energy.

摘要： A system is disclosed for additively manufacturing a composite structure. The system may include a support, a discharge head connected to and moveable by the support, a supply of reinforcement, and a rotary tensioner located between the supply and the discharge head. The rotary tensioner may be configured to impart tension to the reinforcement and to generate a signal indicative of the tension. The system may further include a drive associated with the supply, and a controller in communication with the rotary tensioner and the drive. The controller may be configured to selectively adjust a feed parameter of the drive based on the signal to maintain a desired level of tension.
