Description

The invention relates to a production device and a method for the generative production of a component.

From the field of large format inkjet printing, in particular from the US 2004 0 095 431 A1 , a printhead is known which extends across a width of a print medium. This means that the printhead spans the print media. The printhead has over its width a number of nozzles corresponding to a certain resolution, through which a printing fluid can be applied to the printing medium while the printing medium is guided past the printing head in a straight line.

In a generative manufacturing process, a component made of a particular powdery, pasty or liquid raw material is produced in layers by a chemical and / or physical action on this raw material in layers. These generative manufacturing processes, which are also called additive manufacturing processes, are uneconomical for mass production of a component, since a build-up rate, i. H. a manufacturing or production speed is too low. Accordingly, these manufacturing processes are currently used mainly in prototype production. In addition, it is disadvantageous that set-up times occur during removal of the finished component from the production device, during which time the production device is stationary, that is not produced. Furthermore, it is disadvantageous that for producing a material layer of the component in previous devices for the generative production of components at least two cycles are performed, namely a material application cycle and a solidification cycle. During the material application cycle, the means for solidification stand still and vice versa.

The object of the present invention is to provide a production apparatus and a method for the generative production of a component, by means of which a production speed suitable for a component mass production can be realized.

This object is achieved by a manufacturing apparatus having the features of claim 1 and by a method having the features of claim 9. Advantageous embodiments with expedient developments of the invention are specified in the other claims.

Advantages and advantageous embodiments of the manufacturing device according to the invention are to be regarded as advantages and advantageous embodiments of the method according to the invention and vice versa.

According to the invention, a production device is provided for the generative production of a component, which comprises: a component receptacle for receiving the component to be produced; a material supply device, by means of which a powdery material layer can be introduced into the component receptacle; an active ingredient spraying device, by means of which, in a region of the pulverulent material layer to be fused, it can be wetted by a working fluid which promotes heat conduction; and an irradiation device, by means of which the powdery material layer can be irradiated, wherein the latter can be converted into a cohesive component layer in its region which is to be fused and wetted with the active liquid promoting the heat conduction. In the case of the production device according to the invention, provision is made for the material supply device, the active substance spraying device and the irradiation device to be rotatable about an axis of rotation relative to the component receptacle. In addition, it is provided that the material supply device, the active ingredient supply unit and the irradiation device are movable parallel to the axis of rotation relative to the component holder.

In a generative or additive manufacturing of the component, this is produced in layers. This means that component shapes can be realized on the basis of geometries that can not be realized with conventional production methods. In particular, the component can have a plurality of individual components, for example interlocking chain links, pinions, gears, etc. In other words, the component can also be an assembly, for example a functionally ready transmission.

By means of the material supply device, the powdery material layer, for example a metal or ceramic powder, can be introduced into the component receptacle. In the component holder, the component to be generated can be built up, in particular in layers, d. H. produced.

By means of the Wirkstoffsprüheinrichtung the still loose powder of the powdery material layer is wettable with a kneading liquid, which has the property to forward heat particularly efficiently to the wetted by her material. For this purpose, the Wirkstoffsprüheinrichtung for example, have a plurality of nozzles through which the active liquid can be applied to the still loose powder of the powdery material layer. Under a wetting is to be understood in this context that the particles that the powdery Form material layer on the respective surface are ideally completely covered by the active liquid.

The irradiation device can be, for example, an infrared lamp (abbreviated to IR lamp) which is capable of delivering heat energy, in particular in the form of thermal radiation, to the loose, powdery material layer. Because the wetted with the active liquid areas of the powdery material layer melt faster than the free of the active liquid areas of the powdery material layer, a particularly low energy input to the powdery material layer is necessary to produce a layer of the component to be produced. In other words, at a fixed irradiation period of the powdery material layer, only areas that are in contact with the active fluid melt. Areas of the powdery material layer, which are free of the active liquid, do not melt within this irradiation time.

By the material feeder, the Wirkstoffprüüheinrichtung and the irradiation device, in particular in this order, are rotatable about a common axis of rotation relative to the component receiving, introducing the powdered material layer in the component receiving, wetting the powdery material layer with the active liquid and irradiating the powdery material layer during a rotation of the corresponding devices relative to the component receiving feasible.

Further, since the material supply means, the drug delivery unit, and the irradiation means are movable parallel to the common rotation axis relative to the component holder, a distance between the component holder and each of the material supply means, the drug spray means, and the irradiation means is changeable. This ensures that the component to be produced generatively or additively can be manufactured layer by layer.

Thus, it is necessary for the manufacture of a component layer a single rotation of the material supply device, the material spraying device and the irradiation device with respect to the component holder, which means, for example, beyond the component holder. It is particularly advantageous here that the material feed device, the active ingredient spraying device and the irradiation device are in particular simultaneously active during the twisting, whereby an unproductive time of the respective devices is minimized.

It has proven to be particularly advantageous if the material supply device, the active substance spraying device and the irradiation device together form a production module. In addition, the material supply device, the active ingredient spraying device and the irradiation device can be combined in the form of a structural unit in the production module. This may mean, for example, that the material supply device, the active ingredient spraying device and the irradiation device are combined in a common housing. However, it is just as conceivable that the material supply device, the active substance spraying device and the irradiation device, which form a production module, are arranged at a distance from each other. For example, the material supply device, the active substance spraying unit and the irradiation device, which together form a production module, can be individually covered by a respective housing.

In a further embodiment of the present invention, by means of the active ingredient spraying device in an area of the powdery material layer which is not to be fused, the latter can be wetted with a working fluid which inhibits heat conduction. In other words, the Wirkstoffsprüheinrichtung is able to apply the heat conduction favoring and the heat conduction inhibiting active liquid on the powdery material layer, such that the areas to be merged, the powdery material layer of the heat conduction favoring active liquid are wettable and the non-merging areas the powdery material layer of the heat conduction inhibiting active liquid are wetted. This is advantageous in that heat is conducted more slowly to the powder by means of the heat conduction-inhibiting active liquid, so that the powder wet with the heat-conducting active liquid melts more slowly than the powder wetted with the first liquid. As a result, a particularly accurate edge formation is ensured in the component to be produced.

Furthermore, it is particularly advantageous if a multiplicity of component receptacles and a corresponding number of production modules for simultaneously producing a corresponding number of components are provided in the production device. In particular, it is conceivable that the manufacturing device has more than two component holders and accordingly more than two production modules. Particularly preferred is a ratio of component receptacles to manufacturing modules 1 :1. In a particularly advantageous embodiment, for example, 15 component holders and accordingly 15 production modules can be provided. Since the manufacturing modules each have a common axis of rotation relative to the Component recordings are rotatable, wherein the component receptacles may be arranged, for example, along a circle, thus during the rotation of a production module with respect to a component receiving a number of the component modules corresponding number of component layers can be manufactured.

According to a further advantageous embodiment of the invention, the component holder can be rotatable about the axis of rotation with respect to the manufacturing module. This means that the production module or the production modules are stationary, wherein the component holder or the component holders are rotatable in relation to the production modules about the axis of rotation. For example, the axis of rotation can cut a center of a circle along the circumference of the production modules are arranged and along the circumference of the component holders are rotatable. This is particularly advantageous because the manufacturing module stands still during manufacture of a component layer, which ensures that no shocks adversely affect the manufacturing module.

Alternatively or additionally, the production module can be rotatable about the axis of rotation in relation to the component receptacle. This means that the component receptacle stands still during the manufacture of a component layer, which ensures that no unwanted vibrations have an influence on the component receptacle.

It is also advantageous if a lifting device for lifting the production module is provided parallel to the axis of rotation and in relation to a bottom of the component receptacle. In other words, the lifting device is provided to change a distance between the component holder and the production module. For example, by means of the lifting device, the production module can be raised parallel to the axis of rotation, that is, along the axis of rotation, so that a distance between the component holder and the production module can be increased. Furthermore, by means of the lifting device, the production module can be raised in order to remove a finished component from the component receptacle and / or to remove a component receptacle from the production apparatus and / or to insert a component receptacle into the production apparatus.

In a further advantageous embodiment of the invention, a lowering device for lowering a bottom of the component receptacle is provided parallel to the axis of rotation and in relation to the production module. This means that a distance between the production module and the bottom of the component holder can be changed by means of the lowering device. By means of the lowering device so a bottom of the component holder is lowered along the axis of rotation. A lowering of the bottom of the component holder can take place, for example, if, after twisting the production module via the component holder, a component layer is completed in order to bring the distance between the now completed component layer and the production module at a distance, so that the following component layer can be applied to the part-finished component ,

In addition, the invention relates to a method for the generative production of a component by means of the manufacturing device according to the invention or by means of an advantageous embodiment of the manufacturing device according to the invention. This method comprises the following steps: introduction of the powdery material layer into the component receptacle by means of the material feed device; Wetting the region to be merged with the first active liquid promoting the heat conduction by means of the active ingredient spraying device; Irradiation of the powdery material layer, wherein in the region to be merged with the first, the heat conduction favoring active liquid wetted area is converted to a cohesive component layer, by means of the irradiation device; Rotating the material supply device, the active ingredient supply unit and the irradiation device about the axis of rotation relative to the component receiving means of the manufacturing device; and moving the material supply device, the drug delivery unit and the irradiation device parallel to the rotation axis relative to the component receiving means of the manufacturing device.

In a further embodiment of the method, it is particularly advantageous that, during a working cycle of the production device, a powdery material layer is added to the component receptacle when the workpiece module passes over a component receiving the material supply device, the active ingredient supply unit and the irradiation device This working cycle added material layer is wetted with a first and a second, the heat conduction inhibiting active liquid and the wetted in this working cycle with the two active liquids material layer is irradiated.

This is particularly advantageous because only one overrunning or twisting of the production module with respect to the component holder is to be carried out for manufacturing a component layer. Thus, in each case a component layer can be generated in a particularly efficient manner by means of the production apparatus or by means of the method, which is reflected in particularly low production costs.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively indicated combination but also in other combinations or in isolation.

1 shows a schematic and perspective view of a manufacturing device 1 for the generative production of a component 2 , Generally, in a generative or additive manufacturing process, the component is manufactured 2 from an informal, for example, powdery material which is treated chemically and / or physically layer by layer, so that the component 2 Accordingly, layer by layer is constructed. The individual layers of the component 2 are after their respective completion in particular cohesively connected to each other, for example fused, welded, etc. Since the material of the device layer is selectively, ie partially processed according to a blueprint or the like, to a cohesive composite, can be produced by means of the generative or additive manufacturing process, a component be, which in turn comprises one or more individual components, wherein the components can not be interconnected with each other materially. For example, by means of the generative manufacturing process, a chain component can be manufactured in which individual chain links made in one piece intermesh with one another.

The manufacturing device 1 has a component holder 3 in which the component to be generated can be produced in particular in layers. Preferably, the component holder 3 through a floor 4 and one the ground 4 comprehensive and in particular perpendicular to the ground 4 arranged component receiving wall 5 educated. Accordingly, a recording room 6 above the ground 4 formed, which upwards by a peripheral edge 7 the component receiving wall 5 is limited.

The manufacturing apparatus further comprises a material supply device 8th on, by means of which a powdery material layer in the component holder 3 and especially in the recording room 6 can be introduced. When the powdery material from which the component 2 can be, for example, a powder of metal, plastic and / or ceramic, etc. Ideally, this powder is not produced by means of milling, but directly spherical, whereby particularly advantageous flow properties and / or flowability, etc. are ensured. It is also conceivable that the material from which the component 2 is prepared, liquid or pasty is provided. The material feeder 8th may comprise a container system, wherein the powdery material and / or other powders and / or liquids are storable. In addition, the material supply device 8th have a suction and piping system, via which the powdery material from the container system from the component receiving 3 can be fed. In addition, the material feeder 8th Smoothing comprise, by means of which when introducing a layer of material in the receiving space 6 this material layer is smoothed. Such a smoothing agent may, for example, be a squeegee.

In the manufacturing device 1 is also a Wirkstoffspüheinrichtung 9 provided, which is adapted to apply a first, a heat conduction favoring active liquid on the powdery material layer. In particular, the Wirkstoffsprüheinrichtung 9 arranged to apply the first active liquid, which promotes heat conduction, only on areas of the powdery material layer, which is a layer of the component to be produced 2 form. This means that the active ingredient spraying device along its Length or along its direction of longitudinal extension selectively release the first active liquid on the powdery material layer.

A likewise provided, for example, designed as an infrared lamp irradiation device 10 is adapted to emit radiation toward the powdered material layer. It may preferably be in the irradiation device 10 to act an infrared LED lamp (LED: light emitting diode). Characterized in that the areas of the material layer, which the layer of the component to be produced 2 form, are wetted with the first, the heat conduction favoring active liquid, these areas of the powdery material are melted faster than the areas which are free of the first active liquid. This means that a contour of the component layer to be produced can be determined by a spray pattern of the active substance spraying device. In other words, in the case of an irradiation by means of the irradiation device, only the areas of the powdery material layer which melt and are wetted by the first active liquid promoting the heat conduction melt and fuse. As these areas melt, mix and then cool again, a new, inherently cohesive component layer is created, which is also firmly bonded to the previously produced component layer.

The material feeder 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 can together make up a manufacturing module 11 form. In particular, the manufacturing module 11 a housing, which the material supply device 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 partially encloses. But it is also conceivable that the production module 11 has a plurality of sub-housing, so that the material supply 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 which the manufacturing module 11 form, are arranged away from each other.

In the manufacturing device 1 , what a 1 is shown, it is further provided that the material supply 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 each about a rotation axis 12 relative to the component holder 3 are rotatable. Accordingly, since the material supply 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 in a production module 11 can be summarized, the manufacturing module 11 around the axis of rotation 12 relative to the component holder 3 be rotatable. Here has the axis of rotation 12 a distance from the manufacturing module 11 , which is a distance of the component receiving 3 at least substantially corresponds. In other words, the manufacturing module 11 along a circular path 13 around the axis of rotation 12 being rotated, taking along the circular path 13 also the component holder 3 is arranged so that the manufacturing module 11 that is, the material feeding device 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 the component holder 3 can cover at a distance to this.

Further, in the manufacturing apparatus 1 provided that the material feed 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 or the production module 11 parallel to the axis of rotation 12 relative to the component holder 3 is movable. In other words, the manufacturing module 11 along the axis of rotation 12 adjustable in height, so that a vertical distance 14 between the circumferential edge 7 and a lower edge of the manufacturing module 11 is changeable. Alternatively or additionally, it is conceivable that the component holder 3 its height is adjustable to the vertical distance 14 to change. In particular, the vertical distance 14 changeable to the manufacturing module 11 another sweeping of the component holder 3 or the recording room 6 without allowing the previously completed layer of the component 2 to come across.

2 shows a schematic plan view of the manufacturing device 1 , Here is the production module 11 along the circular path 13 that is about the axis of rotation 12 from the component holder 3 twisted. The material feeder 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 are along the direction of rotation 15 arranged so that when sweeping the manufacturing module 11 about the component holder 3 first the material feeder 8th , then the Wirkstoffprüüheinrichtung 9 and finally the irradiation device 10 about the component holder 3 are mobile. In other words, during a running over or sweeping the component holder 3 through the manufacturing module 11 by means of in the manufacturing module 11 integrated material feeder 8th a powdery material layer in the component holder 3 recoverable. During the same pass over the component holder 3 through the manufacturing module 11 is by means of in the manufacturing module 11 integrated Wirkstoffprüüheinrichtung 9 the previously applied material layer wetted with the first, the heat conduction favoring active liquid. Subsequently, during the same pass over the component holder 3 through the manufacturing module 11 by means of in the manufacturing module 11 integrated irradiation device 10 the applied and in particular partially wetted material layer can be irradiated. In summary, this means that after passing over the component holder 3 through the manufacturing module 11 a layer of the component 2 manufacturable or manufactured.

3 shows a schematic side view of Wirkstoffspüheinrichtung 9 and also a partial section of the powdery material layer and an already manufactured component area 16 , which is an integral part of the component 2 is. That means the part area 16 cohesively with a remainder of the component 2 connected is. The Wirkstoffprüüheinrichtung 9 has a variety of spray units 17 on which are set up, first drops 18 the first, the heat conduction favoring active liquid on a material layer surface 19 to spray. The spray unit 17 are further furnished to second drops 20 a second, the heat conduction inhibiting active liquid on the material layer surface 19 to spray. In particular, the Wirkstoffsprüheinrichtung 9 set up, for example, on the basis of a blueprint, simultaneously by means of a first group of spray units 17 the first drops 18 and by means of a second group of spray units 17 the second drops 20 on the material layer surface 19 to spray.

The second, the heat conduction inhibiting active fluid conducts heat worse than the first, the heat conduction favoring active liquid. This means that the wetted with the second active liquid powder of the material melts slower than the wetted with the first active liquid powder. This also means that with a uniform irradiation of the powdery material layer by the irradiation device 10 only areas of the powdery material layer can be melted or are melted, which are wetted by the first active liquid. Thus, a particularly accurate edge formation in the finally manufactured component can be 2 realize.

The higher the number of spray units 17 along a longitudinal direction 21 the Wirkstoffsprüheinrichtung 9 distributed over the length of which are present, the higher the resolution of the Wirkstoffsprüheinrichtung falls 9 out. Preferably, the resolution is greater than 600 dpi, more preferably a resolution of 1200 dpi.

4 shows a schematic plan view of the manufacturing device 1 with a variety of component shots 3 and a corresponding variety of manufacturing modules 11 at a constant distance circular around the axis of rotation 12 around from component shots 3 arranged. Also around the rotation axis 12 around is a variety of manufacturing modules 11 arranged in a circle. Preferably, just as many component holders 3 circular around the axis of rotation 12 arranged as manufacturing modules 11 circular around the axis of rotation 12 are arranged. By means of such a multiple arrangement of component recordings 3 or production modules 11 is a particularly efficient manufacturing device 1 created. During a twisting of the production modules 11 about the component holders 3 can at the same time in each of the circularly arranged component receiving 3 in each case one more layer of the component 2 to be generated.

In particular, it is possible that in each of the so circularly arranged component receiving 3 each different components 2 are manufacturable. It is equally possible that in each of the circularly arranged component receptacle 3 each the same component 2 is manufacturable. It is also possible that one or more component receptacles 3 from the manufacturing device 1 are removable, so that places where no component recordings 3 are arranged, for example in 4 as a blank space 22 marked, when crossing the blank 22 through one of the manufacturing modules 11 there is no production step executed there.

Also in 4 it can be seen that along the direction of rotation 15 with a twisting of the production modules 11 about the component holders 3 in this order the material feeder 8th , the Wirkstoffspüheinrichtung 9 and finally the irradiation facility 10 about the component holder 3 are rotatable.

5 shows a schematic plan view of the manufacturing device 1 , in which the component holders 3 relative to the manufacturing modules 11 are rotatable. That means the manufacturing modules 11 rotationally fixed with respect to the axis of rotation 12 are arranged. This also means that for a twisting or overrunning of the production modules 11 about the respective component receptacles 3 these under the respective production modules 11 method.

For example, the component holders 3 be arranged on a turntable, through the center of which extends perpendicular to the plane of the drawing axis of rotation 12 passes through. This turntable can be relative to the axis of rotation 12 together with the component holders arranged thereon 3 be rotatable so that upon rotation of the turntable, the component receptacles 3 under the respective production modules 11 are rotatable. During a rotation of the turntable or the respective component receptacles 3 under the respective production modules 11 is a layer of the respective components 2 manufacturable.

Turning the respective component shots 3 according to the direction of rotation 15 under the respective production modules 11 , are in the respective manufacturing module 11 the material supply device 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 arranged accordingly.

6 shows a schematic plan view of the manufacturing device 1 in which the manufacturing modules 11 relative to the component holders 3 are rotatable. This means that the respective component shots 3 in relation to the axis of rotation 12 which is perpendicular to the plane, are arranged rotationally fixed. In contrast, the respective manufacturing modules 11 in relation to the axis of rotation 12 rotatably arranged so that these manufacturing modules 11 over the fixedly arranged component receptacles 3 are mobile away.

Because of the manufacturing modules 11 in each case via the component holders 3 are mobile away, are in the respective production modules, the material supply 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 arranged accordingly. In particular, the material feeding device 8th , the Wirkstoffspüheinrichtung 9 and the irradiation device 10 in the production module 11 arranged exactly the other way round, as in 5 is shown.

With a renewed reference to 1 is in the manufacturing device 1 a lifting device 23 provided by means of which the vertical distance 14 is changeable. The lifting device 23 For example, as a hydraulic and / or pneumatic lifting cylinder or as otherwise driving, z. B. electric linear motor can be formed. The lifting device 23 may alternatively or additionally be removed from the axis of rotation 12 be arranged, for example, in the production module 11 integrated. In particular, by means of the lifting device 23 a production distance 24 be changed, whereby the production distance 24 from the ground 4 the component holder 3 up to a lower edge of the production module 11 or to a respective lower edge of the material feed 8th , the active ingredient sprayer 9 and / or the irradiation device 10 extends. This production distance 24 essentially corresponds to a cumulative height of the already generated layers of the component 2 plus a height which must be present for the functional introduction of the powdered material layer, for wetting the powdery material layer with the first and the second active liquid and for irradiating the powdery material layer.

Alternatively or additionally, the production distance 24 by means of a lowering device 25 be regulated. The sink device 25 can do this with the ground 4 the component holder 3 be connected. The floor 4 the component holder 3 is in this case within the peripheral component receiving wall 5 axially, that is in the vertical direction, displaceable. Is the production module 11 about the component holder 3 gone, that is, is a layer of the component 2 manufactured generatively, is by means of sinking device 25 the floor 4 to a certain extent lowerable, namely at least the height required for generating the following layer of the component 2 must be present.

7 shows a flowchart illustrating one by means of the manufacturing device 1 feasible method for generative production of the component 2 , During a first step S1, the production module travels 11 about the component holder 3 , In the case of the manufacturing module 11 in relation to the axis of rotation 12 is stationary, moves the component holder 3 during the first step S1 below the manufacturing module 11 , During a resulting relative movement between the component holder 3 and the manufacturing module 11 a first substep S1a is carried out during which the powdery material layer is conveyed by means of the material feed device 8th in the component holder 3 introduced, ie in particular on the ground 4 the component holder 3 is applied. Preferably, the material feeding device smoothes 8th by means of the smoothing agent, so for example the doctor, during the substep S1a, the previously applied powdery material layer.

During the first step S1 , in particular during a second sub-step S1b is applied to the previously applied powdery material layer by means of Wirkstoffspüheinrichtung 9 applied the first and the second active liquid. In other words, the powdery material layer by means of Wirkstoffspüheinrichtung 9 with the first, the heat conduction favoring active liquid and the second, the heat conduction inhibiting active liquid wetted.

Furthermore, during the first step S1 a third step s1c executed in which the powdery, wetted with the first and / or with the second active liquid material layer by means of the irradiation device 10 irradiated, so that the powdery material layer is in its merging, with the heat conduction favoring active liquid wetted area is converted to a cohesive component layer. This means that the last irradiated and thus fused layer of the component 2 a cohesive connection with the previously generated, directly adjacent layer of the component 2 received.

In a second step S2 becomes the production distance 24 by means of the lifting device 23 and / or by means of the lowering device 25 modified so that by means of the method another layer of the component 2 , as already described above, can be generated.

Thus, a production device and a method for the generative production of a component are provided, by means of which a production speed suitable for a component series production can be realized. In addition, a pairing is a component pickup 3 and an associated manufacturing module 11 feasible with very low cost. In addition, an energy requirement of the production apparatus and the associated method presented here is lower than, for example, a laser-based production apparatus or a laser-based production method. Finally, the manufacturing device presented here is particularly flexible, since different components can be manufactured at the same time.
