    The invention relates to a method for producing a motor vehicle interior component from a base body, which is at least partially made of a polymeric material, and which is bounded by side edges along its circumference, wherein at least one side edges at least partially, preferably all side edges along the entire circumference of Base body to be provided with a cover on plastic base.
    Furthermore, the invention relates to a motor vehicle interior trim component with a base body which consists at least partially of a polymeric material and which is bounded by side edges along its circumference, wherein at least one side edge at least partially, preferably at all side edges along the entire circumference of the base body, a cover is arranged on plastic base.
    In addition, the invention relates to the use of a 3D printer.
    Automotive interior trim components, such as hat racks, cargo shelves, side panels, door panels, etc., are nowadays partially manufactured as sandwich components with a core element covered on both sides by at least one cover layer, to meet the automotive industry's weight reduction requirements. The core element can be designed as a lightweight component, for example as a honeycomb panel.
    Such components for motor vehicles are now produced partly by pressing the layer structure in a corresponding shape for the contouring. For this purpose, the initially planar surface material of the layer structure is usually superimposed and inserted in the sequence in a press, wherein in the press at the same time the connection of the individual layers takes place, for example by the exercise of pressure and temperature.
    Due to the manufacturing process, the semi-finished products are inserted in an oversize size in the press, so that the final shaping takes place after the pressing. This can be done, for example, with a so-called pinch or dipping edge with a shearing tool, for which purpose the pressed component is inserted into a cutting tool or the die already comprises this cutting tool. The advantage of this method is that the component can be produced in one step. The disadvantage here, however, is that the cut edges have an unclean appearance. Furthermore, the top fabric can fray at the trim edges. A further disadvantage is the fact that the tools usually have a short service life, since the duration of use reduces the quality of the trimming.
    In order to meet these problems, the prior art has already proposed a wide variety of methods for enclosing trim edges.
    Thus, for example, AT 509 944 A1 describes a method for producing a component for a motor vehicle according to which a multilayer main body is produced and cut to form a trim edge at least partially in the edge region, wherein the trim edge in a mold with a mold cavity with at least one plastic for training an edge element is molded or foamed with a plastic.
    From DE 10 2009 046 811 A1 a method for producing a motor vehicle carrier is known, in which after punching the hat rack made of a composite material, a strip is attached to the rear edge of the parcel shelf.
    A disadvantage of the known methods is that they are relatively inflexible with regard to small and very small series of automotive interior trim components, if the edging of the trim edges is to be produced in situ.
    The object of the present invention is to provide a possibility with which automotive interior fitting components can be produced with a series production method in very small series or as a single production.
    The object of the invention is achieved with the aforementioned method, after which the cover is produced by means of a 3D printing process.
    Next, the object of the invention is achieved by the aforementioned automotive interior trim component, wherein the cover is made by means of 3D printing.
    In addition, the object of the invention is achieved by the above-mentioned use of a 3D printer, according to which it is provided that a plastic-based covering element is produced along at least one side edge of a basic body of a motor vehicle interior component, at least partially made of a polymeric material.
    The advantage here is that the cover can be made freely in terms of shape and color and in terms of the plastic base used. In addition, the formation of very narrow cover elements is easily possible, which can be produced with other methods only with great effort. The cover member for edge cover can be manufactured in one step and applied to the blank for the automotive trim component and optionally connected to this. It is thus a corresponding cost reduction feasible. Further cost reductions can be achieved through the elimination or reduction of development costs and the elimination of tooling costs for injection molding tools, extrusion tools, foaming tools, etc., transport costs. Although this method can therefore be used very well for one-off production, it can nevertheless also be used in (mass) series production, so that demand-oriented production can be simplified. In addition, the purchase of automotive trim components by the customer can be simplified by providing the data for the manufacture of the cover member, i. its specific desired shape and its color as well as the location on the automotive interior trim component, etc., in the system of the manufacturer of the automotive interior trim component einspielt. Together with data of the capacity utilization at the manufacturer, the delivery time can thus also be determined or possibly even specified by the customer. By importing the customer data so that the vehicle interior trim component can also be started, if necessary, completely automatically without further intervention by the manufacturer, so that the latter only has to ensure the provision of raw materials to a sufficient extent.
    In the simplest case, the cover element can be designed as a simple edge strip, in particular if the adhesive strength of the cover element on the base body is sufficient due to a correspondingly good material compatibility or if mechanical anchoring is provided.
    But it is also possible that the cover member is the body on both sides encompassing produced, whereby adhesion difficulties can be better countered, since thus between the body and the cover a positive connection can be formed.
    According to one embodiment variant of the method, provision can be made for the base body to be heated at least in the area of the side edge (s) to be provided with the cover element before the cover element is produced. It can thus be improved adhesion of the cover on the body. Further, it can be better avoided that the material for the cover after its application to the body cools too quickly and thereby impurities in the cover arise.
    It can further be provided that at the beginning of the production of the cover element on the base body takes place with a first temperature and at the end with a second temperature, wherein the first temperature is higher than the second temperature. By this embodiment, it can be achieved that at the beginning of the construction of the cover, the plastic base material for the cover flows better, whereby the replica of the contour of the body in the area in which the cover is to be arranged, can be done easily and with higher accuracy. Due to the relatively cooler to bring the plastic base material at the end of the 3D printing in turn, the location-accurate pressure can be improved so that the contours do not "blur" but the shaping of the cover can be done with a higher precision. Due to the reduced flow movement of the plastic base material at the end of the order of the cover, the programming of the cover can also be simplified because influencing factors can be reduced to the form-true deposition of the cover.
    According to an alternative embodiment, provision may be made for the cover element to be produced on the base body using a temperature gradient between the first temperature and the second temperature, whereby a slower lowering of the temperature over time can be achieved. It can thus better avoid errors in the structure of the cover, which may possibly be caused by excessive temperature differences during deposition.
    It is also possible that an undercut groove is formed in at least one, the side edge of the automotive interior trim component 1 forming end face. Also with this embodiment, the adhesion of the cover can be improved on the base body, as can additionally form a positive connection through the undercut. Again, the above embodiment is advantageous, which can take place at a relatively higher temperature at the beginning of training, the structure of the cover, as the undercut can be filled easier and with greater certainty with the plastic base material by the improved flow of the plastic base material for the cover.
    It is also possible for at least one reinforcing element to be formed from a second material in the cover element by means of 3D printing. Again, the strength of the method shows in this embodiment, since the flexibility in terms of shape and position such reinforcing elements can be easily installed and better adapted to the needs in the cover. There are also non-linear versions of such amplification amplifier elements easier to implement.
    On the other hand, it is also relatively easy with the method to produce the cover with a hardness gradient. It is thus an embodiment of the cover easier to represent, in which the subsequent to the main body portion of the cover harder and the outer end portion of the Abdeckeckelementes is relatively softer. On account of this configuration of the cover element, on the one hand the "clattering" of the automotive interior equipment component during the drive can be better avoided. On the other hand, however, so that the investment of the automotive interior trim component can be improved to another component, since the contours of the other component can be better represented by the softer in the investment area cover this.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    Fig. 1 shows an automotive interior equipment component 1 in the form of a luggage compartment cover for a motor vehicle, sometimes referred to as hat rack, in an oblique view. The parcel shelf is designed in particular self-supporting.
    It should already be stated at this point that the automotive interior trim component 1 can also be designed for another purpose in motor vehicles. For example, the automotive interior trim component 1 can be designed as a side panel for a motor vehicle door or a luggage compartment, a pillar, for example the A, B or C pillar of a motor vehicle, as a cargo floor itself, etc. In addition, the automotive interior trim component 1 can also be an acoustic component for a motor vehicle, with which, for example, the noise level in the passenger compartment can be reduced or with which a very specific, intentional background noise is generated in the passenger compartment of the vehicle. In addition, the automotive trim component 1 can also be used in the engine compartment of a motor vehicle, e.g. for the reduction of the noise level.
    The automotive interior trim component 1 comprises a main body 2, which has at least one decorative layer 3 on an upper side 4, which faces the passenger compartment in the closed state of the motor vehicle interior component 1, and one below this decorative layer 4 and preferably connected thereto Core layer 5 has. Optionally, at least one further layer may be arranged between the decorative layer 3 and the core layer 5, as well as a further decorative layer may be arranged on the underside of the automotive interior trim component 1 as needed. Such embodiments of luggage compartment baggage ckunaen. as usually used for Kombinationskraftfahrzeuae who the, in which the trunk, that is, the luggage compartment, is separated from the passenger compartment only about this automotive interior trim component 1, are already known from the prior art.
    The main body 2 is completely or at least partially made of a polymeric material. Preferably, the base body 2 has at least one layer, in particular the core layer 5, which consists at least partially of a thermoplastic and / or thermosetting plastic.
    In the context of the invention, for example, core layers 2 can be used, which have the following structure: first cover layer, foam layer, second cover layer, first cover layer, honeycomb layer, second cover layer, only cover layer.
    The first and / or the second cover layer are preferably made of a thermoplastic and / or thermosetting plastic. In this case, if appropriate, the reinforcing fibers mentioned below may be incorporated.
    The automotive trim component 1 may be formed in one piece, as shown in Fig. 1. There is also the possibility that this consists of several parts, in particular via a film hinge interconnected parts, so that the automotive interior trim component 1 is collapsible or collapsible. Such embodiments are known from the prior art.
    As shown in FIG. 1, at least one recess 6 can be arranged or formed on the upper side 4 of the automotive interior trim component 1.
    The decorative layer 3 can be, for example, a carpet, a fleece, a felt or the like. The core layer 5 can be formed by a foam, for example a polyurethane foam, wherein this foam can be a so-called new foam or a composite foam in which foam particles of waste and residues are joined together with new foam. There is also the possibility that the core layer 5 may be replaced by a honeycomb panel, e.g. is made of cardboard or paper or a plastic, in particular polypropylene, at least partially formed or this core layer 5 may also be formed by a plastic layer, in particular a fiber-reinforced thermoplastic layer. As fibers, both inorganic, for example, glass fibers, carbon fibers, and organic fibers, such as polyester fibers, natural fibers, etc. may be used.
    Such automotive interior trim components 1 are usually made by stacking the individual layers and inserting this layer material in a mold with subsequent pressing, wherein the layer material is usually formed larger than the final automotive trim component 1, so that it is necessary that in the area at least one the side edges 7 a trimming to form at least one trim edge 8 (Fig. 2) is performed. The main body 2 may have such a trimming edge 8 at several or all side edges 7.
    In the area of this trim edge 8, the layer structure appears, so that therefore the core layer 5 can be seen. To cover the trim edge 8 is provided that at least partially a cover 9 is formed or arranged on this. The cover 9 serves on the one hand to cover the exposed layer structure at the end faces of the body or to avoid injury, since the side edges 7 of the body 2 u.U. sharp edged or u.U. Fibers, such as glass fibers, emerge from the core layer 5, if last is formed from a fiber-reinforced plastic.
    The covering element 9 extends in the direction of the circumference of the motor vehicle interior component 1 over at least one part of at least one of the side edges 7. Preferably, the covering element extends entirely along all the side edges 7 at which the layer structure of the base body 2 has been exposed by its processing , in particular continuously along the entire circumference of the basic body 2.
    The cover element 9 is produced by means of 3D printing from at least one, optionally melted, plastic, as will be explained in more detail below.
    FIG. 2 shows a variant of the cover element 9 of the automotive interior trim component 1 connected in the region of the trim edge 8 and in particular to the base body 2. The main body 2 consists in this embodiment of the first, upper decorative layer 3, the core layer 5 and another, arranged on a bottom 10 decorative layer 11, wherein the two decorative layers 10,11 may consist of the same or different materials. As indicated by dashed lines in FIG. 2, at least one further layer 12 may be arranged between the decorative layer 3 and the core layer 5 and / or between the further decorative layer 11 and the core layer 5. It should thus be clarified that the layer structure of the main body 5, in particular the number of the layer, is not limited to the described and shown embodiments.
    In a first embodiment - in FIG. 2, several embodiments are shown - has the cover 9 at least partially with a height 13 which is greater than a layer thickness 14 of the base body 2 viewed in the same direction. This makes it possible that the cover 9 engages around the base body 2 in the region of the side edges 7, so that the cover 9 abuts with legs 15,16 formed thereon on the top 4 and the bottom 10 of the body. It is thus formed a positive connection between the cover 9 and the base body 2.
    In principle, it is also possible for the cover element 9 to cover the base body 2 only on the upper side 4 or only on the lower side 10 so that only one of the legs 15, 16 is formed on the cover element.
    The cover 9 of this embodiment has a substantially symmetrical cross-section, wherein a facing away from the base body 2 front portion 17 of the cover is performed rounded.
    But it is also possible, as indicated by dashed lines in Fig. 2, that the cover 9 is formed in the front region 17 at least approximately tapering, wherein the foremost region is preferably also performed rounded.
    In addition, there is the possibility that at least one reinforcing element 18 is arranged or embedded in the cover element 9, as shown in FIG. 2 with dashed circles. The position and shape of these reinforcing elements 18 depends on the mechanical requirements of the automotive interior trim component 1.
    FIG. 3 shows a further embodiment variant of the automotive interior trim component 1, in which the trim edge 8 at least partially has a cross-sectional taper, so that the base body 2 tapers in the direction of the side edge 7. It should be noted, however, that the illustrated shape of the cross-sectional taper of the base body 2 is not restrictive. In particular, this cross-sectional taper need not be sharp-edged as a offset 19, but may also be provided with a rounding. Furthermore, there is the possibility that the base body 2 is beveled in the region of the edge edge 8.
    The offset 19 may preferably be formed on both opposite surfaces of the base body 2, ie on the upper side 4 and also on the underside opposite this upper side 4, wherein only one of these surfaces may be provided with the offset 19. The offset 19 can be produced for example by the removal of the decorative layer 3 in this area (or by the provision of a decorative layer 3 with smaller dimensions). Due to the offset 19, there is the possibility that the cover element 9 terminates at least approximately planar with the two surfaces of the main body 2.
    It is also possible, as is also shown in Fig. 3, that the base body 2 at least partially a recess 20 which is designed in particular groove-like, wherein the cover 9, that is, the plastic of the cover 9, into this groove-shaped recess 20 gives out, whereby the connection between the cover 9 and the base body 2 of the vehicle interior trim component 1 can be improved. Preferably, this particular groove-shaped recess 20 has a dovetail-shaped cross-section or at least one undercut, whereby the anchoring and connection effect between the cover 9 and the base body 2 is improved. However, it is in principle also possible to provide other cross-sectional shapes, for example a rectangular or a square cross-section, for this recess 20. Furthermore, although this is the preferred embodiment variant, this recess 20 does not necessarily have to be groove-like, but rather several recesses or recesses 20 can be arranged on discrete areas on the base body 2 in the area of the trim edge 8. It is also possible to arrange at least two groove-shaped recesses 20 on the front side.
    In one embodiment, there is the possibility that such, in particular groove-shaped, recesses 20 are arranged not only frontally in the region of the cover 9, but that at least one of the surfaces, that is, for example, the top 4 or the bottom of the base body 2 at least Such a recess 20 for the same purpose in the region of the trim edge 8, that is, the cover 9, is provided.
    Dashed line is indicated in Fig. 3, that in the cover 9 and at least one cavity 21 may be present, which may in particular extend continuously over the entire length of the cover 9 in the circumferential direction of the automotive interior trim component 1. By means of this at least one cavity 21, the covering element 9 can be given a reduced rigidity, whereby it can, for example, better reshape contours on which it comes into contact, even if the covering element 9 itself is made of a harder plastic or if a damping effect is produced ,
    4, for the sake of completeness, a simple embodiment variant of the automotive interior equipment component 1 is shown. Its base body 2 consists only of the core layer 5 and a decorative layer 3. The cover 9 is designed as a simple bar, for example with a rectangular cross-section.
    It is also possible, as is known per se for hat racks, that at least one fastening element 22 is arranged on the motor vehicle interior component 1 in order to be able to fasten the rear parcel shelf to a tailgate of a motor vehicle. Such fastening elements 22 are known from the prior art and consist for example of a holding device 23, an associated, in particular cord-shaped, element 24 and connectable to the tailgate, in particular suspended ring member 25 (Fig. 1). This fastening element 22 or the holding device 23 or the fastening elements 22 or holding devices 23 can be subsequently arranged on the automotive interior trim component 1, in particular on the front side, or they are already attached to the base body 2 of the motor vehicle trim component 1 prior to the formation of the cover element 9 so that the plastic for the production of the cover 9 of this fastener 22 and this holding device 23 at least partially encloses and thus partially anchored in the cover 9. For this purpose, the fastening element 22 or the holding device 23 may also have appropriate provisions, such as hook-shaped elements or the like, which are optionally profiled and / or provided with openings, so that a better anchoring of the fastening element 22 and the holding device 23 in the cover 9 reaches can be.
    It is within the scope of the invention, the possibility that the base body 2 has a plurality of trimming edges 8, e.g. when the main body 2 is cut from a larger molded part, stamped, etc., wherein at least two such trim edges 8 adjoin one another. In this case, it is advantageous if the transition between two trim edges 8 is provided with a rounding.
    It should be noted that the embodiments of the automotive interior trim component 1 described above are not restrictive in terms of shape and layer structure, but merely illustrative
    Have character, although these variants are preferred embodiments of the automotive interior trim component 1.
    Furthermore, the term "trim edge" is to be seen broadly. It is not absolutely necessary that the trimming of the basic body 2 of the motor vehicle
    Interior equipment component 1 is carried out in the course of the method according to the invention. It is also already ready-made materials for the construction of the body 2 of the automotive interior trim component 1 are used. In addition, the trimming of the body does not necessarily have to be done by punching, but other cutting tools can be used. In addition, a trimming is not absolutely necessary if the individual layers of the main body 2 of the automotive interior trim component 1 are already produced in the correct size.
    The cover element 9 for the at least partially, in particular entire, edge surround of the main body 2 of the automotive interior trim component 1 is produced with a 3D printing process from a polymer plastic, i. printed. The polymeric plastic may be a thermoplastic, a thermoset or an elastomer or a mixture of at least two of these plastics. For example, PP, PET, ABS-PC, ABS, PLA, TPE, PUR, etc. can be used as the plastic. Preferably, a thermoplastic material is used, in particular ABS or PP. But it is also possible that the cover 9 is made of more than one plastic by, for example, various polymeric plastics are printed in layers or by a polymeric plastic from another polymer plastic is at least partially covered, for example, a certain surface finish of the cover 9 reach, or by the above-described at least one reinforcing element 18 is also made of a polymeric plastic which is different, to the polymeric plastic of the remaining cover member 9, in particular harder or stiffer. The 3D printing method has the advantage that the different polymeric plastics can be printed in one step.
    If the at least one reinforcing element 18 is provided and produced by means of the 3D printing method, a plastic material selected from a group comprising or consisting of PET, PA, PUR, epoxy resin, ABS can be used as the polymeric material for this purpose. Other suitable plastics are also usable. However, it is also possible for the reinforcing element 18 to be made of fibers, e.g. Glass fibers, carbon fibers, basalt fibers, etc., can be formed.
    As shown schematically in FIG. 5, according to the 3D printing method, the base body 2 of the motor vehicle interior component 1, which as described above may have the core layer 5, the decorative layer 3 and the decorative layer 11, or may consist of these layers, means a printing head 26, the cover 9 made of the at least one, optionally molten, polymeric plastic by the polymeric plastic is printed on the base body 2 at the appropriate locations (see above description). The print head 26 can be mounted on a robot 27 for this purpose. Further, the print head 26 may be multi-dimensionally movable. Alternatively or additionally, it is also possible that the base body 2 with a corresponding holding device, in particular multi-dimensional, is kept movable.
    The print head 26 is designed such that it can discharge the material to be printed in small, layered webs, to which the print head 26 has discharge elements, which are designed accordingly. Preferably, the printhead 26 may be heated and / or cooled. If appropriate, the printhead 26 can also have at least one UV lamp for processing UV-curing plastics.
    The print head 26 is connected via a line 28 with at least one reservoir 29. In the reservoir 29, the raw material or the polymer material from which the cover 9 is to be prepared, kept in stock and fed from this the print head 26.
    As indicated by dashed lines in Fig. 5, the cover 9 is constructed in layers. By means of appropriate data, which are made available to the arithmetic unit of the 3D printer, the desired contours of the cover element 9, that is to say the overlapping of the base body 2 by the cover element 9 shown by way of example in FIG.
    Depending on the design of the print head 26 and / or the sequence of movements, the cover element 9 can be constructed in its entirety over its length or in sections in layers.
    As a 3D printing method, in particular, a method with molten material, such as FDM (Fused Deposition Modeling) or with UV-curable material, such as. MJM (multi-jet modeling) applied. However, other 3D printing methods can also be used.
    As can be seen from FIG. 6, the 3D printing method can be part of a production line 30 for (serial) production of the automotive interior trim component 1. The production line 30 may include or consist of a first station 31, a forming station 32 and a printing station 33 in the direction of production. In the first station 31, the individual layers for the production of the main body 2, that is to say, for example, the core layer 5 and the decorative layers 3, 11 or further layers corresponding to the desired layer structure, can be superimposed and optionally heated. In the following shaping station 32, this desired planar shape can be given the desired shape in a press and the individual layers can be connected to one another. It may be possible for the station 31 and the forming station 32 to be combined so that the layer materials are stacked, deformed and shaped directly in the forming station and joined together. The trimming of the vehicle interior trim component 1 can take place in the shaping station 32 or in a downstream station, before the covering element 9 is applied. The stations 31 and / or 32 can be formed or used according to the state of the art. You can be equipped with at least one Beschnittele element for the automotive interior trim component 1. Any necessary trimming can also be done in a separate tool.
    After the forming station 32, the printing station 33 follows, in which the cover element 9 is produced with the print head 26 (FIG. 5). This printing station 33 can have a processing chamber or processing cabin, in which the print head 26 and optionally the robot 27 is or are arranged. The processing chamber or processing cabin can be made closed. The printing station 33 can be arranged directly after the forming station 32. But it is also possible that the pressure takes place after an intermediate storage of the cover 9 in the course of mounting additional attachments.
    According to one embodiment variant of this method for producing the covering element 9, provision can be made for the base body 2 of the motor vehicle interior component 1 to be heated at least in the region of the side edge (s) 7 to be provided with the covering element 9 before the covering element 9 is produced. In particular, the base body 2 (depending on its material) can be heated to a temperature which is selected from a range of 50 ° C to 200 ° C or is selected from a range of 30% to 80% of the melting temperature of the plastic from the the cover 9 is made. For several plastics used, this is the temperature of the plastic melting at the lowest temperature.
    The temperature of the base body 2, for example, by means of infrared radiator, hot air, hot stamp, etc., take place.
    It can further be provided that at the beginning the covering element 9 is produced on the base body 2 at a first temperature and at the end at a second temperature, wherein the first temperature is usually higher than the second temperature.
    According to one embodiment, it can be provided that the production of the cover 9 on the base body 2 using a
    Temperature gradient between the first temperature and the second temperature takes place. The temperature gradient can be selected from a range of 10C / layer application to 10 ° C / layer application.
    It can further be provided that the cover 9 is made with a hardness gradient. The hardness gradient can be controlled, for example, by appropriate data and / or choice of material, wherein based on the data and / or choice of material, the raw material composition for producing the cover 9 is changed. The 3D printing device may have more than one storage container 29, in which different polymeric plastics or raw materials are contained for this purpose.
    The exemplary embodiments show possible embodiments of the automotive interior equipment component 1, the 3D printing device and the production line 30.
    For the sake of order, it should finally be pointed out that for a better understanding of the structure of the automotive interior trim component 1, the 3D printing device and the production line 30, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
