A system for additively manufacturing a composite structure is disclosed. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may be configured to discharge a continuous reinforcement that is at least partially coated in a liquid matrix. The system may also include a cure enhancer connected to the print head and configured to expose the discharge to cure energy to cause the, and a controller in communication with the heater and the cure enhancer. The controller may be configured to selectively activate the heater and the cure enhancer.

Assignee:
Continuous Composites Inc. - Coeur d'Alene ID
International Classification:
B29C 64/209 B29C 64/264 B29C 64/241
Abstract:
A head is disclosed for an additive manufacturing system. The head may include an outlet configured to discharge a continuous reinforcement at least partially coated in a liquid matrix. The head may also include a low-pressure port located upstream of the outlet and configured to draw out only liquid matrix.
System And Head 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 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.
Fiber Management Arrangement And Method For Additive Manufacturing System
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.
Additive Manufacturing System Having Stowable Cutting Mechanism

International Classification:
B29C 64/209 B33Y 30/00 B33Y 50/02 B29C 64/393
Abstract:
An additive manufacturing system is disclosed for use in fabricating a composite structure. The additive manufacturing system may include a print head configured to discharge a continuous reinforcement that is at least partially wetted with a matrix, and a support configured to move the print head in at least one dimension during discharge. The additive manufacturing system may also include a cutting mechanism connected to at least one of the print head and the support. The cutting mechanism may be configured to selectively sever the continuous reinforcement from the print head. The cutting mechanism may include a cutting implement, a first actuator configured to move the cutting implement from a stowed position to a deployed position, and a second actuator configured to engage the cutting implement with the continuous reinforcement.

Assignee:
CC3D LLC - Coeur d'Alene ID
International Classification:
B29C 64/188 B29C 64/307 B29C 64/209
Abstract:
A system is disclosed for use in additively manufacturing a composite structure. The system may include a head configured to discharge a continuous reinforcement. The system may further include an external applicator configured to apply a matrix to the discharged continuous reinforcement, and a cure enhancer configured to expose the matrix to a cure energy at a side of the external applicator opposite the head.
Additive Manufacturing System Implementing Hardener Pre-Impregnation
A method is disclosed for additively manufacturing a composite structure. The method may include directing a continuous reinforcement into a print head, and coating the continuous reinforcement with a first matrix component inside of the print head. The method may further include coating the continuous reinforcement with a second matrix component, discharging the continuous reinforcement through a nozzle of the print head, and moving the print head in multiple dimensions during the discharging. The first and second matrix components interact to cause hardening of a matrix around the continuous reinforcement.
