Definitions
- Continuous fiber 3D printing involves the use of continuous fibers embedded within a matrix discharging from a moveable print head.
- the matrix can be a traditional thermoplastic, a powdered metal, a liquid resin (e.g., a UV curable and/or two-part resin), or a combination of any of these and other known matrixes.
- a head-mounted cure enhancer e.g., a UV light, an ultrasonic emitter, a heat source, a catalyst supply, etc.
- a cure enhancer e.g., a UV light, an ultrasonic emitter, a heat source, a catalyst supply, etc.
- CF3D® provides for increased strength, compared to manufacturing processes that do not utilize continuous fiber reinforcement, improvements can be made to the structure and/or operation of existing systems. For example, Applicant has found that when discharging tracks of composite material adjacent each other, lamination strength between adjacent tracks can be improved via selective control over discharge trajectory.
- the disclosed additive manufacturing system is uniquely configured to provide these improvements and/or to address other issues of the prior art.
- the present disclosure is directed to an additive manufacturing system.
- 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 that is oriented at an oblique angle relative to a central axis of the print head.
- the present disclosure is directed to a method of additively manufacturing a structure.
- the method may include discharging a material through an outlet of a print head onto a surface.
- the method may also include orienting the print head in a direction normal to the surface during discharging of a first track of the material, and orienting the print head at an oblique angle relative to the surface during discharging of a second track of the material adjacent the first track of the material.
- the method may further include moving the print head over the surface during discharging.
- the present disclosure is directed to another method of additively manufacturing a structure.
- This method may include discharging a material through an outlet of a print head onto a surface, wherein the outlet is oriented at an angle relative to a central axis passing through the print head.
- the method may further include moving the print head over the surface during discharging.
- the method may also include pivoting the outlet about the central axis to a first angle at which a first track of material is discharged directly behind the print head relative to a movement direction of the print head, and pivoting the outlet about the central axis to a second angle at which a second track of material is discharged to a side of the print head relative to the movement direction and adjacent the first track of material.
- FIG. 1 is a diagrammatic illustration of an exemplary disclosed additive manufacturing system
- FIG. 2 is diagrammatic illustration of an exemplary disclosed print head that may be used in conjunction with the additive manufacturing system of FIG. 1 ;
- FIG. 3 is a pictorial diagram depicting an exemplary disclosed method that may be performed by the additive manufacturing system of FIG. 1 and the print head of FIG. 2 ;
- FIGS. 4 and 5 are diagrammatic illustrations of exemplary portions of the print head of FIG. 2 .
- FIG. 1 illustrates an exemplary system 10 , which may be used to manufacture a composite structure 12 having any desired shape.

Abstract
Description
- This application is a continuation of U.S. Non-Provisional application Ser. No. 16/744,937 that was filed on Jan. 16, 2020, which is based on and claims the benefit of priority from U.S. Provisional Application No. 62/797,078 that was filed on Jan. 25, 2019, the contents of all of which are expressly incorporated herein by reference.
- The present disclosure relates generally to a manufacturing system and, more particularly, to a system for additively manufacturing composite structures.
- Continuous fiber 3D printing (a.k.a., CF3D®) involves the use of continuous fibers embedded within a matrix discharging from a moveable print head. The matrix can be a traditional thermoplastic, a powdered metal, a liquid resin (e.g., a UV curable and/or two-part resin), or a combination of any of these and other known matrixes. Upon exiting the print head, a head-mounted cure enhancer (e.g., a UV light, an ultrasonic emitter, a heat source, a catalyst supply, etc.) is activated to initiate and/or complete curing of the matrix. This curing occurs almost immediately, allowing for unsupported structures to be fabricated in free space. When fibers, particularly continuous fibers, are embedded within the structure, a strength of the structure may be multiplied beyond the matrix-dependent strength. An example of this technology is disclosed in U.S. Pat. No. 9,511,543 that issued to Tyler on Dec. 6, 2016 (“the '543 patent”).
- Although CF3D® provides for increased strength, compared to manufacturing processes that do not utilize continuous fiber reinforcement, improvements can be made to the structure and/or operation of existing systems. For example, Applicant has found that when discharging tracks of composite material adjacent each other, lamination strength between adjacent tracks can be improved via selective control over discharge trajectory. The disclosed additive manufacturing system is uniquely configured to provide these improvements and/or to address other issues of the prior art.
- In one aspect, the present disclosure is directed to an additive manufacturing system. 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 that is oriented at an oblique angle relative to a central axis of the print head.
- In another aspect, the present disclosure is directed to a method of additively manufacturing a structure. The method may include discharging a material through an outlet of a print head onto a surface. The method may also include orienting the print head in a direction normal to the surface during discharging of a first track of the material, and orienting the print head at an oblique angle relative to the surface during discharging of a second track of the material adjacent the first track of the material. The method may further include moving the print head over the surface during discharging.
- In yet another aspect, the present disclosure is directed to another method of additively manufacturing a structure. This method may include discharging a material through an outlet of a print head onto a surface, wherein the outlet is oriented at an angle relative to a central axis passing through the print head. The method may further include moving the print head over the surface during discharging. The method may also include pivoting the outlet about the central axis to a first angle at which a first track of material is discharged directly behind the print head relative to a movement direction of the print head, and pivoting the outlet about the central axis to a second angle at which a second track of material is discharged to a side of the print head relative to the movement direction and adjacent the first track of material.

FIG. 1 illustrates anexemplary system 10, which may be used to manufacture acomposite structure 12 having any desired shape.System 10 may include asupport 14 and deposition head (“head”) 16.Head 16 may be coupled to and moved bysupport 14. In the disclosed embodiment ofFIG. 1 ,support 14 is a robotic arm capable of movinghead 16 in multiple directions during fabrication ofstructure 12.Support 14 may alternatively embody a gantry (e.g., an overhead-bridge or single-post gantry) or a hybrid gantry/arm also capable of movinghead 16 in multiple directions during fabrication ofstructure 12. Althoughsupport 14 is shown as being capable of 6-axis movements, it is contemplated thatsupport 14 may be capable of movinghead 16 in a different manner (e.g., along or around a greater or lesser number of axes). In some embodiments, a drive may mechanically couplehead 16 to support 14, and include components that cooperate to move portions of and/or supply power or materials tohead 16. -
Head 16 may be configured to receive or otherwise contain a matrix (shown as M inFIG. 2 ). The matrix may include any types or combination of materials (e.g., a liquid resin, such as a zero-volatile organic compound resin, a powdered metal, etc.) that are curable. Exemplary resins include thermosets, single- or multi-part epoxy resins, polyester resins, cationic epoxies, acrylated epoxies, urethanes, esters, thermoplastics, photopolymers, polyepoxides, thiols, alkenes, thiol-enes, and more. In one embodiment, the matrix insidehead 16 may be pressurized (e.g., positively and/or negatively), for example by an external device (e.g., by an extruder, a pump, etc.—not shown) that is fluidly connected tohead 16 via a corresponding conduit (not shown). In another embodiment, however, the pressure may be generated completely inside ofhead 16 by a similar type of device. In yet other embodiments, the matrix may be gravity-fed into and/or throughhead 16. For example, the matrix may be fed intohead 16, and pushed or pulled out ofhead 16 along with one or more continuous reinforcements (shown as R inFIG. 2 ). In some instances, the matrix insidehead 16 may need to be kept cool and/or dark in order to inhibit premature curing or otherwise obtain a desired rate of curing after discharge. In other instances, the matrix may need to be kept warm and/or illuminated for similar reasons. In either situation,head 16 may be specially configured (e.g., insulated, temperature-controlled, shielded, etc.) to provide for these needs. - The matrix may be used to at least partially coat any number of continuous reinforcements (e.g., separate fibers, tows, rovings, socks, and/or sheets of continuous material) and, together with the reinforcements, make up a portion (e.g., a wall) of
composite structure 12. The reinforcements may be stored within or otherwise passed throughhead 16. When multiple reinforcements are simultaneously used, the reinforcements may be of the same material composition and have the same sizing and cross-sectional shape (e.g., circular, square, rectangular, etc.), or a different material composition with different sizing and/or cross-sectional shapes. The reinforcements may include, for example, carbon fibers, vegetable fibers, wood fibers, mineral fibers, glass fibers, plastic fibers, metallic fibers, optical fibers (e.g., tubes), etc. It should be noted that the term “reinforcement” is meant to encompass both structural and non-structural (e.g., functional) types of continuous materials that are at least partially encased in the matrix discharging fromhead 16. - The reinforcements may be exposed to (e.g., at least partially coated with) the matrix while the reinforcements are inside
head 16, while the reinforcements are being passed tohead 16, and/or while the reinforcements are discharging fromhead 16. The matrix, dry (e.g., unimpregnated) reinforcements, and/or reinforcements that are already exposed to the matrix (e.g., pre-impregnated reinforcements) may be transported intohead 16 in any manner apparent to one skilled in the art. In some embodiments, a filler material (e.g., chopped fibers, nano particles or tubes, etc.) may be mixed with the matrix before and/or after the matrix coats the continuous reinforcements. - One or more cure enhancers (e.g., a UV light, an ultrasonic emitter, a laser, a heater, a catalyst dispenser, etc.) 18 may be mounted proximate (e.g., within, on, and/or adjacent)
head 16 and configured to enhance a cure rate and/or quality of the matrix as it is discharged fromhead 16.Cure enhancer 18 may be controlled to selectively expose portions ofstructure 12 to energy (e.g., UV light, electromagnetic radiation, vibrations, heat, a chemical catalyst, etc.) during material discharge and the formation ofstructure 12. The energy may trigger a chemical reaction to occur within the matrix, increase a rate of the chemical reaction, sinter the matrix, harden the matrix, or otherwise cause the matrix to cure as it discharges fromhead 16. The amount of energy produced bycure enhancer 18 may be sufficient to cure the matrix beforestructure 12 axially grows more than a predetermined length away fromhead 16. In one embodiment,structure 12 is completely cured before the axial growth length becomes equal to an external diameter of the matrix-coated reinforcement. - The matrix and/or reinforcement may be discharged from
head 16 via any number of different modes of operation. In a first example mode of operation, the matrix and/or reinforcement are extruded (e.g., pushed under pressure and/or mechanical force) fromhead 16 ashead 16 is moved bysupport 14 to create features ofstructure 12. In a second example mode of operation, at least the reinforcement is pulled fromhead 16, such that a tensile stress is created in the reinforcement during discharge. In this second mode of operation, the matrix may cling to the reinforcement and thereby also be pulled fromhead 16 along with the reinforcement, and/or the matrix may be discharged fromhead 16 under pressure along with the pulled reinforcement. In the second mode of operation, where the matrix is being pulled fromhead 16 with the reinforcement, the resulting tension in the reinforcement may increase a strength of structure 12 (e.g., by aligning the reinforcements, inhibiting buckling, etc.) after curing of the matrix, while also allowing for a greater length ofunsupported structure 12 to have a straighter trajectory. That is, the tension in the reinforcement remaining after curing of the matrix may act against the force of gravity (e.g., directly and/or indirectly by creating moments that oppose gravity) to provide support forstructure 12. - The reinforcement may be pulled from
head 16 as a result ofhead 16 being moved bysupport 14 away from ananchor point 20. In particular, at the start of structure formation, a length of matrix-impregnated reinforcement may be pulled and/or pushed fromhead 16, deposited ontoanchor point 20, and at least partially cured, such that the discharged material adheres (or is otherwise coupled) toanchor point 20. Thereafter,head 16 may be moved away fromanchor point 20, and the relative movement may cause the reinforcement to be pulled fromhead 16. It should be noted that the movement of reinforcement throughhead 16 could be assisted via internal feed mechanisms (not shown), if desired. However, the discharge rate of reinforcement fromhead 16 may primarily be the result of relative movement betweenhead 16 andanchor point 20, such that tension is created within the reinforcement. As discussed above,anchor point 20 could be moved away fromhead 16 instead of or in addition tohead 16 being moved away fromanchor point 20. -
Head 16 may include, among other things, anoutlet 22 and amatrix reservoir 24 located upstream ofoutlet 22. In one example,outlet 22 is a single-channel nozzle configured to discharge composite material having a generally circular, tubular, or rectangular cross-section. The configuration ofhead 16, however, may allowoutlet 22 to be swapped out for another outlet (e.g., a nozzle-less outlet—not shown) that discharges composite material having a different shape (e.g., a flat or sheet-like cross-section, a multi-track cross-section, etc.). Fibers, tubes, and/or other reinforcements may pass through matrix reservoir 24 (or another internal wetting mechanism—not shown) and be wetted (e.g., at least partially coated and/or fully saturated) with matrix prior to discharge. - A
controller 26 may be provided and communicatively coupled withsupport 14 andhead 16. Eachcontroller 26 may embody a single processor or multiple processors that are programmed and/or otherwise configured to control an operation ofsystem 10.Controller 26 may include one or more general or special purpose processors or microprocessors.Controller 26 may further include or be associated with a memory for storing data such as, for example, design limits, performance characteristics, operational instructions, tool paths, and corresponding parameters of each component ofsystem 10. Various other known circuits may be associated withcontroller 26, including power supply circuitry, signal-conditioning circuitry, solenoid driver circuitry, communication circuitry, and other appropriate circuitry. Moreover,controller 26 may be capable of communicating with other components ofsystem 10 via wired and/or wireless transmission. - One or more maps may be stored within the memory of
controller 26 and used during fabrication ofstructure 12. Each of these maps may include a collection of data in the form of lookup tables, graphs, and/or equations. In the disclosed embodiment, the maps may be used bycontroller 26 to determine movements ofhead 16 required to produce desired geometry (e.g., size, shape, material composition, performance parameters, and/or contour) ofstructure 12, and to regulate operation of cure enhancer(s) 18 and/or other related components in coordination with the movements. - As can be seen in
FIGS. 1 and 2 , in addition to cure enhancer(s) 18,outlet 22, andmatrix reservoir 24, some embodiments ofhead 16 may include acompactor 28 located at a trailing side ofoutlet 22.Compactor 28 may be rigid or compliant, and configured to compact the matrix-coated reinforcement during and/or after discharge from outlet 22 (e.g., before and/or during curing by cure enhancer(s) 18). -
Compactor 28 may embody any type of compactor known in the art. For example,compactor 28 may embody a shoe (seeFIG. 1 ), a roller (seeFIG. 2 ), a wiper, a skirt, and/or a combination of any of these and other types of compactors known in the art. In the disclosed embodiments,compactor 28 is biased (e.g., via a spring—30) against material discharging fromoutlet 22. It is contemplated, however, thatspring 30 could be omitted, if desired. - In some applications, it can be difficult to properly coalesce or merge together adjacent tracks (shown as T in
FIG. 3 ) of material lying within the same general plane or on the same surface. For example,head 16 may typically be oriented such that its central axis A (e.g., an axis of symmetry extending centrally throughoutlet 22 to support 14) lies within a plane P that encompasses the track T of material being discharged (e.g., is coincident with an axis of the track T) and a normal n to the surface ofstructure 12. In some applications,head 16 is also leaned within plane P into the direction of travel (e.g., such that a distal tip ofoutlet 22 trails behind the rest of head 16). As the material is discharged fromhead 16 in the conventional manner, the material is urged throughoutlet 22 in the normal direction against the underling surface, and in some instances is compressed by the tip ofoutlet 22 and/orcompactor 28 in the same normal direction. While adequate for some applications, there may be little to no force urging the currently discharging track T2 of material transversely into the previously discharged track T1 of material. This can result in low levels of adhesion between these tracks. - As can be seen in
FIG. 3 ,head 16 may be selectively tilted out of plane P in a direction away from the previously discharged material by an angle a. In one embodiment, angle a may be an oblique angle (e.g., about 1-60°). This tilting may cause the current track of material T2 discharging fromoutlet 22 to be pressed against both the underlying surface (e.g., in the normal direction) and against the adjacent and previously discharged track of material T1 (e.g., in the transverse direction). This may help to merge track T2 at least partially into track T1, thereby creating more adhesion between the tracks. - In addition to discharging the track T2 at the angle α against the underlying surface and against the adjacent track T1,
compactor 28 may follow behindoutlet 22 and press track T2 against the adjacent track T1. For example,compactor 28 may generate pressure on the track T2 in general alignment with the angle α (e.g., a normal to a compaction surface ofcompactor 28 may be generally aligned with the angle α). It is contemplated thatcompactor 28 may be shaped and/or selectively oriented to apply pressure against the track T2 in general alignment with the angle α, even whenoutlet 22 and/orhead 16 are (e.g., even when axis A is) oriented in the conventional manner (e.g., not tilted away from the plane P), if desired. It is further contemplated that axis A may be tilted at a first angle α that is different than a second angle α at whichcompactor 28 may be tilted (e.g., as shown inFIG. 3 ). As mentioned above,compactor 28 may be rigid and deform only the track while applying pressure, or be compliant and at least partially deform around the track being discharged and/or any adjacent tracks while applying the pressure. In some embodiments, deformation ofcompactor 28 may reduce migration of liquid matrix away from the reinforcement(s) caused by the application of pressure. That is, the deformation may help to channel the matrix into a desired location and/or shape. - The tilting of axis A during material discharge may be regulated by
controller 26 through selective motions ofsupport 14. To facilitatecompactor 28 being tilted to an angle α that is different than a tilt angle α of axis A,compactor 28 may be mounted to head 16 via a coupling capable of swiveling, pivoting, rotating, or otherwise tilting independently ofoutlet 22 in a transverse direction (e.g., relative to a travel direction of head 16). In some embodiments,compactor 28 may be free to pivot when pressed against a surface ofstructure 12. In other embodiments, however, one or more actuators may be associated withcompactor 28 regulated bycontroller 26 to selectively orientcompactor 28 in a desired manner relative to axis A. - In another embodiment, it is contemplated that, instead of or in addition to selectively tilting axis A to improve transverse adhesion between adjacent tracks of material,
outlet 22 could include a permanent bend. For example,FIGS. 4 and 5 illustrate a distal portion (e.g., the nozzle tip) ofoutlet 22 as being bent at the desired angle α relative to the surface normal n and/or relative to axis A. In these embodiments, the bent portion ofoutlet 22 may be directed to trail behind the rest of outlet 22 (seeFIG. 5 ), such that the material of a given track is discharged against the underlying surface ofstructure 12 and in a direction behind head 16 (e.g., relative to a travel direction). And during discharge of a subsequent track of material (seeFIG. 4 ),outlet 22 may be pivoted about axis A, such that the material is discharged both against the underlying surface ofstructure 12 and against the adjacent track. - The disclosed system may be used to manufacture composite structures having any desired cross-sectional shape and length. The composite structures may include any number of different fibers of the same or different types and of the same or different diameters, and any number of different matrixes of the same or different makeup. Operation of
system 10 will now be described in detail. - At a start of a manufacturing event, information regarding a desired
structure 12 may be loaded into system 10 (e.g., intocontroller 26 that is responsible for regulating operations ofsupport 14 and/or head 16). This information may include, among other things, a size (e.g., diameter, wall thickness, length, etc.), a contour (e.g., a trajectories, surface normal, etc.), surface features (e.g., ridge size, location, thickness, length; flange size, location, thickness, length; etc.), connection geometry (e.g., locations and sizes of couplings, tees, splices, etc.), reinforcement selection, matrix selection, track locations and corresponding angles α, etc. It should be noted that this information may alternatively or additionally be loaded intosystem 10 at different times and/or continuously during the manufacturing event, if desired. Based on the component information, one or more different reinforcements and/or matrix materials may be installed and/or continuously supplied intosystem 10. - To install the reinforcements, individual fibers, tows, and/or ribbons may be passed through
matrix reservoir 24 andoutlet 22. In some embodiments, the reinforcements may also need to be connected to a pulling machine (not shown) and/or to a mounting fixture (e.g., to anchor point 20). Installation of the matrix material may include filling head 16 (e.g., reservoir 24) and/or coupling of an extruder (not shown) tohead 16. - The component information may then be used to control operation of
system 10. For example, the in-situ wetted reinforcements may be pulled and/or pushed from head(s) 16 assupport 14 selectively moves (e.g., based on known kinematics ofsupport 14 and/or known geometry of structure 12), such that the resultingstructure 12 is fabricated as desired. In some instances, the axis A ofhead 16 may be maintained generally normal to the surface ofstructure 12 upon which head 16 is depositing material. For example, when a first track of material is being deposited upon a given surface, the axis A ofhead 16 may be oriented generally normal to the surface. As explained above, this orientation may result in maximum adhesion between the first track of material and the surface. However, in other instances, for example when a second track of material is being deposited adjacent the first track of material onto the surface, the axis A ofhead 16 and/orcompactor 28 may be selectively tilted away from the normal during discharge. As also explained above, this tilting may result in simultaneous discharge of material in the second track against both the underlying surface and the adjacent track of material. This may provide greater adhesion of the second track of material to the adjacent first track than otherwise possible with material discharge and/or compacting in only the normal direction. - Operating parameters of
support 14, cure enhancer(s) 18,compactor 28 and/or other components ofsystem 10 may be adjusted in real time during material discharge to provide for desired bonding, strength, and other characteristics ofstructure 12. Oncestructure 12 has grown to a desired length,structure 12 may be severed fromsystem 10. - It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed system. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed system. For example, although
compactor 28 has been described as being located at a trailing side ofoutlet 22, it is contemplated thatcompactor 28 could alternatively function as a tool center point forsystem 10, if desired. It is intended that the specification and examples be considered as exemplary only, with a true scope being indicated by the following claims and their equivalents.
