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.

A fiber application head for the production of composite material parts, including a compacting roller having a rigid central tube, at least one cylindrical piece made of an elastically deformable flexible material, assembled on the central tube and a plurality of independent rigid rings stacked side by side on the cylindrical piece. Each cylindrical piece includes a cylindrical outer surface by which each ring is intended to come to bear against the lay-up surface, and two collars mounted on the central tube, on either side of the cylindrical piece, being able to block in translation the stack of rings on the cylindrical piece.

Disclosed is an automated fiber placement (AFP) device for preform manufacturing. The AFP device includes a feeder configured to feed a sheet-type fiber composite material, a molding part configured to mold a sheet-type structure by allowing a roller member to compress the sheet-type fiber composite material, and a compressing part configured to compress an upper surface of the structure, thereby disposing the sheet-type structure on a substrate in a state of maintaining the shape of the sheet-type structure. Particular, the compressing part moves from one end to the other end of the substrate, thereby compressing the sheet-type structure.

A method and apparatus for the additive manufacturing of three-dimensional objects are disclosed. Two or more materials are extruded simultaneously as a composite, with at least one material in liquid form and at least one material in a solid continuous strand completely encased within the liquid material. A means of curing the liquid material after extrusion hardens the composite. A part is constructed using a series of extruded composite paths. The strand material within the composite contains specific chemical, mechanical, or electrical characteristics that instill the object with enhanced capabilities not possible with only one material.

A cutting assembly and a cutter are provided, wherein, in an apparatus for additive manufacturing with a filament, a deposition head has a body and an applicator for fixing a run of filament to a surface at a deposition location ending at a deposition termination point. The cutter assembly has a fixation element for fixing the cutter assembly relative to the deposition head, and a cutter movable relative to the fixation element. The deposition head has a deposition termination configuration and a cutting configuration, and after fixing the run of filament, the deposition head transitions from the deposition termination configuration to the cutting configuration. The cutter cuts the filament only when the deposition head is in the cutting configuration.

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.

Automated fiber placement (AFP) cutter blade assemblies, AFP cutter systems including the same, and associated methods. An AFP cutter blade assembly includes a blade base and a reversible blade insert configured to be coupled to the blade base in either of a first cutter blade configuration, in which a first cutting edge is an active cutting edge, and a second cutter blade configuration, in which a second cutting edge is the active cutting edge. In examples, an AFP cutter system includes a plurality of AFP cutter blade assemblies in combination with an actuator assembly. In examples, a method of reconfiguring a reversible blade insert of an AFP cutter blade assembly includes uncoupling the reversible blade insert from a blade base, rotating the reversible blade insert relative to the blade base, and operatively coupling the reversible blade insert to the blade base in a different configuration.

A computer-implemented method comprising, under the control of one or more computer systems or non-volatile storage medium configured with executable instructions: acquiring a digital model comprising two or more spatial dimensions of an object to be manufactured; forming a three-dimensional model decomposition of the object to be manufactured, wherein forming the three-dimensional model decomposition comprises segmenting at least a portion of the digital model comprising two or more spatial dimensions into one or more surface-based component models; and forming, on one or more surfaces of the one or more surface-based component models, one or more paths comprising one or more elongate fiber tow models.

A compaction device for use with an automated fiber placement machine includes multiple compaction rollers mounted for independent displacement on a supporting frame. The attitude of the compaction rollers change relative to each other when fiber tows are laid up at an angle over an edge of a tool in order to maintain compaction pressure on the tows and thereby reduce non-compacted areas of the tows.

There is described an online inspection method and system having an illumination system that provides bright-field and dark-field illumination concurrently or sequentially, at varying intensities, in order to acquire images that may be read by an image processing device. The image processing device may obtain measurements of features in the images and evaluate acceptability of the features.
