Abstract
Description
- This application is based on and claims the benefit of priority from U.S. Provisional Application No. 62/526,448 that was filed on Jun. 29, 2017, the contents of which are expressly incorporated herein by reference.
- The present disclosure relates generally to a print head and, more particularly, to a print head for use in an additive manufacturing system.
- Continuous fiber 3D printing (a.k.a., CF3D™) involves the use of continuous fibers (e.g., carbon fibers, glass fibers, optical tubes, wires, etc.) 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 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 fibers, it may be difficult to maintain a desired spatial and/or orientational relationship between adjacent fibers during multi-fiber printing. For example, when printing a structure made up of carbon fibers that are simultaneously deposited adjacent to metallic wires, that are simultaneously deposited adjacent to optical tubes, it can be difficult to prevent the carbon fibers, wires, and tubes from overlapping, twisting, or otherwise moving away from a desired state during trajectory changes (e.g., cornering) of the print head. The disclosed print head is uniquely configured to address this and/or other issues of the prior art.
- In one aspect, the present disclosure is directed to a print head for an additive manufacturing system. The print head may include a nozzle having an internal passage and at least one ellipsoidal orifice. The print head may also include a fiber guide disposed at least partially inside the nozzle and dividing the internal passage into a plurality of channels. A length of each of the plurality of channels extends in an axial direction of the nozzle.
- In another aspect, the present disclosure is directed to another print head for an additive manufacturing system. This print head may include a matrix reservoir, and a nozzle in fluid communication with the matrix reservoir. The nozzle may have an internal passage and at least one ellipsoidal orifice located at an end of the internal passage opposite the matrix reservoir. The print head may also include a plurality of radially oriented dividers disposed at least partially inside the nozzle and dividing the internal passage into a plurality of channels. A length of each of the plurality of channels extends in an axial direction of the nozzle.
- In yet another aspect, the present disclosure is directed to a method of additively manufacturing a composite structure. The method may include wetting a plurality of separate reinforcements with a matrix, and directing the wetted plurality of separate reinforcements through a fiber guide inside a nozzle of a print head. The method may also include discharging the wetted plurality of separate reinforcements through an orifice of the nozzle, and moving the print head during discharging to create a three-dimensional trajectory in the wetted plurality of separate reinforcements. The method may further include exposing the wetted plurality of separate reinforcements to a cure energy after discharge from the nozzle, and selectively rotating the fiber guide while moving the print head to maintain an orientational relationship between the plurality of separate reinforcements.
-
FIG. 1 is a diagrammatic illustration of an exemplary disclosed additive manufacturing system; and -
FIGS. 2 and 3 are cross-sectional illustrations of an exemplary disclosed print head that may be utilized with the additive manufacturing system ofFIG. 1 . -
FIG. 1 illustrates anexemplary system 10, which may be used to continuously manufacture acomposite structure 12 having any desired cross-sectional shape (e.g., circular, ellipsoidal, polygonal, etc.).System 10 may include at least asupport 14 and a print 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, such that a resulting longitudinal axis ofstructure 12 is three-dimensional. It is contemplated, however, thatsupport 14 could alternatively be an overhead 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 multi-axis movements, it is contemplated that any other type ofsupport 14 capable of movinghead 16 in the same or in a different manner could also be utilized, if desired. In some embodiments, a drive may mechanically couplehead 16 to support 14 and may include components that cooperate to move and/or supply power or materials tohead 16. -
Head 16 may be configured to receive or otherwise contain a matrix. The matrix may include any type of material (e.g., a liquid resin, such as a zero-volatile organic compound resin; a powdered metal; etc.) that is curable. Exemplary matrixes include thermosets, single- or multi-part epoxy resins, polyester resins, cationic epoxies, acrylated epoxies, urethanes, esters, thermoplastics, photopolymers, polyepoxides, thiols, alkenes, thiol-enes, reversible resins (e.g., Triazolinedione, a covalent-adaptable network, a spatioselective reversible resin, etc.) and more. In one embodiment, the matrix insidehead 16 may be pressurized, for example by an external device (e.g., an extruder or another type of pump—not shown) that is fluidly connected tohead 16 via a corresponding conduit (not shown). In another embodiment, however, the matrix pressure may be generated completely inside ofhead 16 by a similar type of device. In yet other embodiments, the matrix may be gravity-fed through and/or mixed withinhead 16. In some instances, the matrix insidehead 16 may need to be kept cool and/or dark to inhibit premature curing; while in other instances, the matrix may need to be kept warm for the same reason. In either situation,head 16 may be specially configured (e.g., insulated, chilled, and/or warmed) to provide for these needs. - The matrix may be used to coat, encase, or otherwise at least partially surround any number of continuous reinforcements (e.g., separate fibers, tows, rovings, ribbons, and/or sheets of material) and, together with the reinforcements, make up at least a portion (e.g., a wall) of
composite structure 12. The reinforcements may be stored within (e.g., on separate internal spools—not shown) or otherwise passed through head 16 (e.g., fed from external spools). When multiple reinforcements are simultaneously used, the reinforcements may be of the same type and have the same diameter and cross-sectional shape (e.g., circular, square, flat, etc.), or of a different type with different diameters and/or cross-sectional shapes. The reinforcements may include, for example, carbon fibers, vegetable fibers, wood fibers, mineral fibers, glass fibers, metallic wires, optical tubes, etc. It should be noted that the term “reinforcement” is meant to encompass both structural and non-structural types of continuous materials that can be at least partially encased in the matrix discharging fromhead 16. - The reinforcements may be exposed to (e.g., coated with) the matrix while the reinforcements are inside
head 16, while the reinforcements are being passed to head 16 (e.g., as a prepreg material), and/or while the reinforcements are discharging fromhead 16, as desired. The matrix, dry reinforcements, and/or reinforcements that are already exposed to the matrix (e.g., wetted reinforcements) may be transported intohead 16 in any manner apparent to one skilled in the art. - The matrix and reinforcement may be discharged from a
nozzle 18 ofhead 16 via at least two different modes of operation. In a first mode of operation, the matrix and reinforcement are extruded (e.g., pushed under pressure and/or mechanical force) fromnozzle 18, ashead 16 is moved bysupport 14 to create the 3-dimensional shape ofstructure 12. In a second mode of operation, at least the reinforcement is pulled fromnozzle 18, such that a tensile stress is created in the reinforcement during discharge. In this mode of operation, the matrix may cling to the reinforcement and thereby also be pulled fromnozzle 18 along with the reinforcement, and/or the matrix may be discharged fromnozzle 18 under pressure along with the pulled reinforcement. In the second mode of operation, where the matrix is being pulled fromnozzle 18, the resulting tension in the reinforcement may increase a strength ofstructure 12, while also allowing for a greater length of unsupported material to have a straighter trajectory (i.e., the tension may act against the force of gravity to provide free-standing support for structure 12). - The reinforcement may be pulled from
nozzle 18 as a result ofhead 16 moving away from ananchor point 20. In particular, at the start of part-formation, a length of matrix-impregnated reinforcement may be pulled and/or pushed fromnozzle 18, deposited ontoanchor point 20, and cured, such that the discharged material adheres toanchor point 20. Thereafter,head 16 may be moved away fromanchor point 20, and the relative movement may cause additional reinforcement to be pulled fromnozzle 18. It should be noted that the movement of the reinforcement throughhead 16 could be assisted (e.g., via internal feed mechanisms), if desired. However, the discharge rate of the reinforcement fromnozzle 18 may primarily be the result of relative movement betweenhead 16 andanchor point 20, such that tension is created within the reinforcement. -
Nozzle 18 may be fluidly connected to amatrix reservoir 22. Althoughmatrix reservoir 22 is shown as being at least partially inside ofhead 16, it should be noted thatmatrix reservoir 22 could alternatively be located separately upstream ofhead 16. As shown inFIG. 2 ,nozzle 18 may have a generally cylindricalouter wall 24, with an upstream orbase end 26 in fluid communication withmatrix reservoir 22, a downstream ortip end 28, and one or more generally-axially orientedinternal passages 30 that extend frombase end 26 to tipend 28. - Any number of reinforcements (represented as R in
FIG. 2 ) may be passed axially throughreservoir 22 where at least some matrix-wetting occurs (matrix represented as M inFIG. 2 ), and discharged fromhead 16 vianozzle 18. One ormore orifices 32 may be located attip end 28 ofnozzle 18 to accommodate passage of the matrix-wetted reinforcements. In the disclosed embodiment, a single generally ellipsoid (e.g., circular or oval)orifice 32 is shown. It is contemplated, however, thatmultiple orifices 32 could be used. In addition,orifices 32 of another shape may allow for printing of bundles having different cross-sectional shapes. In the embodiment ofFIG. 2 , thesingle orifice 32 is substantially aligned (e.g., aligned within engineering tolerances) with a central axis ofnozzle 18. - Returning to
FIG. 1 , one or more cure enhancers (e.g., one or more light sources, ultrasonic emitters, lasers, heaters, catalyst dispensers, microwave generators, etc.) 34 may be mounted proximate head 16 (e.g., at a trailing side of nozzle 18) and configured to enhance a cure rate and/or quality of the matrix as it is discharged fromnozzle 18.Cure enhancer 34 may be controlled to selectively expose internal and/or external surfaces ofstructure 12 to energy (e.g., light energy, electromagnetic radiation, vibrations, heat, a chemical catalyst or hardener, etc.) during the formation ofstructure 12. The energy may increase a rate of chemical reaction occurring within the matrix, sinter the material, harden the material, or otherwise cause the material to cure as it discharges fromnozzle 18. - A
controller 36 may be provided and communicatively coupled withsupport 14,head 16, and any number and type ofcure enhancers 34.Controller 36 may embody a single processor or multiple processors that include a means for controlling an operation ofsystem 10.Controller 36 may include one or more general- or special-purpose processors or microprocessors.Controller 36 may further include or be associated with a memory for storing data such as, for example, design limits, performance characteristics, operational instructions, matrix characteristics, reinforcement characteristics, characteristics ofstructure 12, and corresponding parameters of each component ofsystem 10. Various other known circuits may be associated withcontroller 36, including power supply circuitry, signal-conditioning circuitry, solenoid/motor driver circuitry, communication circuitry, and other appropriate circuitry. Moreover,controller 36 may be capable of communicating with other components ofsystem 10 via wired and/or wireless transmission. - One or more maps may be stored in the memory of
controller 36 and used during fabrication ofstructure 12. Each of these maps may include a collection of data in the form of models, lookup tables, graphs, and/or equations. In the disclosed embodiment, the maps are used bycontroller 36 to determine desired characteristics ofcure enhancers 34, the associated matrix, and/or the associated reinforcements at different locations withinstructure 12. The characteristics may include, among others, a type, quantity, and/or configuration of reinforcement and/or matrix to be discharged at a particular location withinstructure 12, and/or an amount, intensity, shape, and/or location of desired curing.Controller 36 may then correlate operation of support 14 (e.g., the location and/or orientation of head 16) and/or the discharge of material from head 16 (a type of material, desired performance of the material, cross-linking requirements of the material, a discharge rate, etc.) with the operation ofcure enhancers 34, such thatstructure 12 is produced in a desired manner - In some instances, when multiple reinforcements are being discharged through
nozzle 18 at the same time, it may be beneficial to maintain a desired spatial and/or orientational relationship between the reinforcements. For example, it may be important to avoid overlapping, twisting, and/or reordering of the different reinforcements for purposes of performance (e.g., electrical conductivity, strength, flexibility, noise interference, etc.) and/or appearance. For this purpose, afiber guide 38 may be placed inside of head 16 (e.g., inside of nozzle 18). - An
exemplary fiber guide 38 is illustrated inFIGS. 2 and 3 .Fiber guide 38 may extend an entire length ofnozzle 18 or only a fraction of the length ofnozzle 18. For example,fiber guide 38 may start at base end 26 (or at a point betweenbase end 26 and tip end 28), and terminate short oforifice 32. Alonger fiber guide 38 may reduce a likelihood of entanglements withinnozzle 18, while terminating short oforifice 32 may allow the separate fibers to coalesce into a cohesive bundle prior to discharge fromnozzle 18. In one embodiment, a length offiber guide 38 is about 10-95% of the axial length ofnozzle 18. -
Fiber guide 38 may include a plurality ofdividers 40 thatsegment passage 30 into one or more elongated channels 42. A length of each channel 42 may be oriented in the same general direction as the axis ofnozzle 18. Each channel 42 may be configured to independently receive a particular reinforcement or grouping of reinforcements and to maintain separation of these reinforcement(s) from other reinforcement(s) simultaneously discharging fromnozzle 18. In the embodiment ofFIGS. 2 and 3 , five different channels 42 are created by a general cross-shape. The cross shape may be formed by four radially orientedplanar dividers 40 that are joined to each other at their inner edges. Channels 42 may include fourperipheral channels 42 a, and acenter channel 42 b. It is contemplated however, thatdividers 40 could alternativelysegment passage 30 into only peripheral channels (e.g., quarter- or half-moon shaped channels) 42 a, into asingle center channel 42 b and a single annular-shaped peripheral channel (not shown), or into any other number of center and/or peripheral channels 42. Lower and/or upper ends ofdividers 40 may be rounded to avoid damaging the reinforcements during discharge. - It should be noted that, while the disclosed
dividers 40 are generally planar and dividenozzle 18 into open-sided channels 42 (i.e., channels without an outer radial wall), other configurations ofdividers 40 and channels 42 may also be possible. For example, channels 42 could be completely enclosed by the extension ofdividers 40 radially outward to the annular wall ofpassage 30 or by additional divider walls that extend obliquely betweenadjacent dividers 40. Alternatively, channels 42 could be formed by separate axial tubes that are arranged adjacent each other. In addition, whilechannels 42 a are shown as each having a greater axial cross-sectional area (seeFIG. 3 ) thanchannel 42 b, it is contemplated that the opposite may be true in some embodiments. The cross-sectional area of each ofchannels 42 a may be the same (shown inFIG. 3 ) or different. Finally, it is contemplated thatfiber guide 38 may be removably installed withinnozzle 18, and selectively swapped out for afiber guide 38 having a different configuration. This may be accomplished, for example, by the removal ofnozzle 18 from the remainder ofhead 16, the withdrawing of thefirst fiber guide 38, the insertion of thesecond fiber guide 38, and the reassembly ofnozzle 18. - It is contemplated that
fiber guide 38 could be driven to rotate in some applications. In particular, the continuous reinforcements discharging fromnozzle 18 may need to have a particular orientation regardless of the movements imparted bysupport 14 on head 16 (e.g., regardless of cornering of head 16). It is contemplated thathead 16 may be rotated independent ofsupport 14, thatnozzle 18 could be rotated independent of the rest of head 16 (e.g., of matrix reservoir 22), and/or thatfiber guide 38 could be rotated independent ofnozzle 18 to achieve the desired orientation of the associated reinforcements. For this purpose, a rotary actuator (e.g., a gear, a motor, etc.) 44 may be connected betweensupport 14 and head 16 (shown inFIG. 1 ), betweennozzle 18 and matrix reservoir 22 (not shown), and/or betweenfiber guide 38 and nozzle 18 (shown inFIG. 2 ), as desired. - It should be noted that
fiber guide 38 could be rotated even whenhead 16 is not changing trajectory. In this situation, the rotation offiber guide 38 would result in a controlled twisting and/or overlapping of the discharging reinforcements. - The disclosed system and print head may be used to continuously manufacture composite structures having any desired cross-sectional size, shape, length, density, and/or strength. The composite structures may include any number of different reinforcements of the same or different types, diameters, shapes, configurations, and consists, each coated with a common matrix. In addition, the disclosed print head may allow for multiple simultaneously discharging reinforcements to maintain a desired spatial and/or orientational arrangement, even when the orientation of the print head is changing (e.g., curing cornering). 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 36 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 trajectory), surface features (e.g., ridge size, location, thickness, length; flange size, location, thickness, length; etc.) and finishes, connection geometry (e.g., locations and sizes of couplings, tees, splices, etc.), location-specific matrix stipulations, location-specific reinforcement stipulations, desired spatial and/or orientational relationships between adjacent reinforcements, primary load directions, 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 matrixes may be selectively installed and/or continuously supplied intosystem 10. - Installation of the reinforcements may be performed by passing individual reinforcements or groups of reinforcements down through
matrix reservoir 22, and then threading the separate reinforcements through channels 42 inside ofnozzle 18. Installation of the matrix may include fillingreservoir 22 withinhead 16 and/or coupling of an extruder or external bath (not shown) tohead 16.Head 16 may then be moved bysupport 14 under the regulation ofcontroller 36 to cause matrix-coated reinforcements to be placed against or on a correspondingstationary anchor point 20.Cure enhancers 34 withinhead 16 may then be selectively activated to cause hardening of the matrix surrounding the reinforcements, thereby bonding the reinforcements to anchorpoint 20. - The component information may then be used to control operation of
system 10. Specifically, the reinforcements may be pulled and/or pushed from nozzle 18 (along with the matrix), whilesupport 14 selectively moveshead 16 in a desired manner during curing, such that an axis of the resultingstructure 12 follows a desired trajectory (e.g., a free-space, unsupported, 3-D trajectory). For example,support 14 may movehead 16 in an X-, Y-, and/or Z-direction away fromanchor point 20, such that matrix-wetted reinforcements may be pulled separately through channels 42 and then allowed to coalesce just prior to discharge throughorifice 32. The use offiber guide 38 may inhibit a spatial relationship change between adjacent reinforcements during changes in the trajectory ofhead 16. - During the movement of
head 16, even though the spatial relationships between adjacent reinforcements may be maintained viafiber guide 38, it may still be possible for the resulting structure to vary in orientation of its associated reinforcements, unless otherwise accounted for. For example, a change in the trajectory ofhead 16 from a purely Y-direction to a purely X-direction could cause the discharging bundle of the reinforcements to roll. For instance, a side-discharging reinforcement could become a top-discharging reinforcement during the trajectory change described above. This may be acceptable in some situations. - However, in other situations, it may be beneficial to cause
fiber guide 38 to rotate during the trajectory change ofhead 16. In the example described above,fiber guide 38 may be rotated by about 90° during the trajectory change ofhead 16, such that the side-discharging reinforcement remains the side-discharging reinforcement after the change in trajectory. The rotation offiber guide 38 may be accomplished, for example, bycontroller 36 selectively energizingrotary actuator 44.Controller 36 may coordinate operation ofrotary actuator 44 with the motion ofhead 16 imparted bysupport 14, such that the individual fibers are maintained in a desired spatial and/or orientational relationship. Oncestructure 12 has grown to a desired size and/or length,structure 12 may be disconnected (e.g., severed) fromhead 16 in any desired manner. - It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed system and head. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed system and head. 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.
