    The invention relates to a method for producing a motor vehicle interior component from a base body having a top side and a bottom side, wherein an attachment element based on at least one polymer plastic is arranged on the base body.
    Furthermore, the invention relates to a motor vehicle interior trim component with a base body having a top side and a bottom side, wherein an attachment element based on at least one polymer plastic is arranged on the base body.
    In addition, the invention relates to the use of a 3D printer.
    Currently attachments are applied to automotive interior trim components of the automotive industry, such as hat racks, load floors, side and door panels, using a variety of methods, such as welding (ultrasonic, friction, infrared welding), gluing, riveting, screwing, clipping, etc. For this purpose, it is necessary that the attachments previously in a tool, e.g. an injection molding tool, an extrusion tool, etc., manufactured and then applied with an additional step on the automotive interior trim component.
    The present invention has for its object to provide a method for producing automotive interior trim components with add-on elements or to create such a vehicle interior trim component.
    The object of the invention with the aforementioned method, in which the attachment element is produced by means of a 3D printing method, is achieved.
    Next, the object of the invention is achieved by the aforementioned automotive interior trim component in which the attachment is made by means of 3D printing.
    In addition, the object of the invention is achieved by the aforementioned use of a 3D printer, according to which it is provided that the attachment element is applied to plastic base on a base body of a vehicle interior trim component by means of 3D printing.
    The advantage here is that the attachment can be made freely in terms of shape and color and in terms of the plastic base used. So it can be produced with the process without changing the machine equipment a variety of attachments. Optionally, several attachments can be made in one step. In addition, the formation of very narrow extension elements is easily possible, which can be produced with other methods only with great effort. The attachment can be made in one step and applied to the blank for the automotive trim component and optionally connected to this. This makes it possible to realize a corresponding cost reduction. Another cost reduction is the elimination or reduction of development costs and the elimination of tool cost for injection molding tools, extrusion tools, foaming tools, etc., transport costs, reachable. 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 the automotive trim components by the customer can be simplified by providing the data for the Fierstellung of the attachment, i. its specific desired shape and its color as well as the location on the automotive interior trim component, etc., einspielt in the system of Fierstellers the automotive interior trim component. Together with data of the capacity utilization at the Fiersteller the delivery time can be determined thereby 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.
    Preferably, as attachment elements as fasteners, retaining elements, reinforcing elements, acoustically active elements, optical elements, damping or balancing elements are produced, which can be visibly attached, since - as already mentioned - the shape (if not exclusively for technical reasons) and the color the attachments are freely selectable. These attachments must therefore no longer be hidden, but can be adapted to the space requirements in a car also be made visible on the body in the car. In other words, the attachments can be made more adapted to their use.
    For these reasons, it is also possible that the attachment is made on the top or the bottom of the body. This also has the advantage that the production of attachments can be simplified because these surfaces of the body are usually better accessible.
    For better connection of the add-on element to the main body, i. For more tear-resistant connection with it, can be provided according to a variant that the attachment is the base body frontally made at least partially encompassing, so that a positive connection is formed. The attachment can additionally take over the function of edge protection.
    Also, to improve the connection of the attachment with the body can be provided that in at least one end face of the body a, in particular undercut, groove is formed and the attachment is made reaching into the groove. By the undercut a positive connection can be achieved, which can lead to a further improvement of the connection of the attachment element with the main body.
    If the attachment element is attached to the upper side or to the underside of the base body, it is advantageous for the same reasons if a recess is made in the base body and the attachment element is produced starting in the recess, it being possible according to an embodiment variant to provide the recess is made with an undercut, whereby the pull-out strength of the attachment can be further improved.
    It is particularly advantageous if, according to another embodiment variant, the base body is produced from a core layer on which at least one cover layer is applied on both sides and is arranged over the part of the attachment element in the recess, the two cover layers being connected to one another. It can thus be significantly increased the necessary pull-out forces to remove the attachment element.
    According to one embodiment variant of the method, provision can be made for the base body to be heated at least in the area in which the attachment element is printed, before the covering element is imprinted. 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 the printing of the attachment 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 attachment element, the plastic base material flows better for the attachment, whereby the replica of the contour of the body in the area in which the attachment is to be arranged, can be done easily and with higher accuracy. Due to the relatively cooler application of 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 Fomnaebuna for the attachment can be made with a higher precision. Due to the reduced flow movement of the plastic base material at the end of the order of the add-on element also the programming of the add-on element can be simplified because influencing factors can be reduced to the form-true deposition of the add-on element. This embodiment variant is also particularly advantageous in combination with the embodiment described above, in which an (undercut) groove or a (rear-cut) recess formed as the groove or the recess o-the improved flow of the plastic base material for the attachment The undercut can be filled in more easily and with greater safety with the plastic base material.
    According to one embodiment variant, it can be provided that the printing of the attachment element on the base body using a temperature rgradienten between the first temperature and the second temperature takes place, whereby a slower lowering of the temperature over time can be achieved. It can thus better avoid errors in the structure of the attachment, which may be caused by excessive temperature differences during deposition.
    It is also possible for at least one reinforcing element to be formed from a second material in the attachment 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 adapted to the needs better adapted to the attachment. There are also non-linear versions of such reinforcing elements easier to implement.
    On the other hand, it is also relatively easy with the method to produce the attachment with a hardness gradient. It is thus an embodiment of the attachment easier to represent, in which the adjoining the body portion of the attachment harder and the outer end portion of the attachment to it is relatively softer or vice versa. This design of the attachment element so that the system of the car Innenausstattunasbauteils can be improved to another component, since the Kon tures of the other component can be better represented by the softer in the investment area attachment of this. On the other hand, it can also be used to easily adapt the acoustic effect of the add-on element.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    In FIGS. 1 to 3, various automotive trim components 1 are shown. Thus, Fig. 1 shows an inner door panel, Fig. 2 a loading floor and Fig. 3 a sound insulation for an engine compartment. These automotive trim components 1 are representative of a number of other automotive interior trim components 1, such as hat racks, (side) trim for a trunk or a pillar, such as the A, B or C pillar of a motor vehicle. 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 illustrations in FIGS. 1 to 3 are therefore not intended to be limiting for the scope of the invention.
    This automotive interior equipment components 1 according to FIGS. 1 to 3 has in common that they have at least one attachment element 2 (mounting element). This at least one attachment element 2 is arranged on an upper side and / or a lower side and / or an end face 5 of a base body 6 of the motor vehicle interior component 1 and at least partially connected to the base body 6.
    The attachment element 2 may be, for example, a door handle (FIG. 1), a fastening element (FIG. 2, bottom), a reinforcing element on an outer surface of the automotive interior trim component (FIG. 2, dashed line), or an acoustic element (FIG. 3). However, other types of attachments 2 used in automotive construction are also possible, such as hooks, eyelets, speaker mounts, armrests, axles, clamps, buffers, fixing members, such as those shown in FIGS. Tabs, slots, etc.,.
    The attachment 2 consists at least partially, in particular entirely, of at least one polymeric plastic. This polymeric plastic may be a thermoplastic, a thermoset or an elastomer or a mixture of at least two of these plastics. For example, as the plastic, PA, PP, PET, ABS-PC, ABS, PLA, TPE, PUR, etc. can be used. Preferably, a thermoplastic material is used, in particular ABS or PP.
    The main body 6 of the automotive interior trim component 1 may be formed one or more layers. For example, the main body 6 can have at least one decorative layer 7 on the top side 3 and a core layer 8 arranged below this decorative layer 7 and preferably connected thereto, as shown in FIG. 4. If appropriate, at least one further layer can be arranged between the decorative layer 7 and the core layer 8. Likewise, on the underside of the vehicle interior trim component 1, a further decorative layer 9 can be arranged if necessary, as can be seen from FIG. 5. Such embodiments of automotive interior trim components 1 are known per se.
    Preferably, the base body 6 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, first and / or second cover layer only.
    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.
    If the base body 6 is designed as a single layer, the one layer is the core layer 8.
    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.
    The decorative layer 7 and / or the decorative layer 9 can be formed, for example, by a carpet, a fleece, a felt or the like. The core layer 8 may be formed by a foam, for example a polyurethane foam, which foam may 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 8 is covered by a honeycomb panel, e.g. is made of cardboard and / or paper and / or a plastic, in particular polypropylene, at least partially formed or this core layer 8, inter alia, by a plastic layer, in particular a fiber-reinforced thermoplastic layer, be formed. As fibers, both inorganic, for example, glass fibers, carbon fibers, and organic fibers, such as polyester fibers, natural fibers, etc. may be used.
    Multilayer automotive interior trim components 1 can be produced by laying the individual layers on top of one another and inserting this layer material into a press mold with subsequent pressing. The core layer 8 alone can be pressed into shape accordingly.
    The at least one attachment element 2 is produced by means of 3D printing from at least one, possibly molten, polymeric plastic, as will be explained in more detail below.
    The concrete shape of the attachment 2 depends on the particular purpose.
    FIG. 4 shows a section of a motor vehicle interior component 1. In the base body 2, a recess 10 is formed. The recess 10 extends in the concretely illustrated embodiment of the top 3 through the upper decorative layer 7 into the core layer 8. It is also possible that the recess 10 is formed only in the decorative layer 7. For the sake of completeness it should be noted that the recess 10 can also be formed on the underside 4, if the attachment element 2 is arranged on the underside of the base body 2.
    As further shown in broken lines in FIG. 1, the recess 10 can also be designed with an undercut 11.
    In this embodiment variant of the vehicle interior trim component 1, the attachment element 2 extends into the recess 10 and preferably completely fills it, whereby a better connection with the base body 6 is achieved and thus the peel strength or tear resistance can be increased. The attachment 2 is thus made starting in the recess.
    FIG. 5 shows a detail of a motor vehicle interior component 1, in which-as has already been explained above-the base body 6 consists of the decorative layer 7, the core layer 8 connected thereto, and the decorative layer 9 connected thereto. However, the recess 10 not only extends into the core layer 8 but extends the recess 10 from the top 3, i. the outer surface of the decorative layer 7 up to or into which the second core layer 9. The recess 10 thus penetrates the core layer 8 in its entirety.
    The attachment element 2 in turn extends into the recess 10 and fills these partially or preferably entirely. In any case, the add-on element 2, i. its part, which is formed in the base body 6, from the upper side 3 to the lower decorative layer 9, whereby the two decorative layers 7, 9 are connected to each other via the add-on element 2. This is particularly because the add-on element 2 is printed from a, possibly molten, plastic and thus can also form a connection with the two decorative layers 7, 9 and optionally the core layer 8. It can thus be achieved a further improvement of the connection with the base body 6 and thus the peel strength or tear resistance can be increased. The Anbauele element 2 is thus produced in this embodiment, starting in the recess 10.
    In a continuation of this embodiment of the automotive interior trim component 1, the recess 10 can be formed to extend through the entire cross section of the base body 6, so that the attachment element 2 extends at least from the upper side 3 to at least the lower side 4.
    In Fig. 6 it is shown that the attachment element 2 and the front side 5 of the main body 6 of the vehicle interior trim component 1 can be arranged encompassing, wherein the clasping can be formed so far that the attachment 2 from the top 3 on the front page. 5 extends to the bottom 4, as indicated by dashed lines. It can thus be formed a positive connection between the attachment element 2 and the base body 6. In order to achieve this, the main body 6 and / or a nozzle or nozzle unit of the 3D printer can be correspondingly moved / rotated during the pressing.
    Further, there is the possibility, as also shown in Fig. 6, that the base body 6 at least partially a recess 12 which is executed in particular groove-like, wherein the attachment element 2, that is the plastic of the attachment element 2, into this Recess 12 extends, whereby the connection between the attachment element 2 and the base body 6 of the vehicle interior trim component 1 can be improved. The recess 12 may also have an undercut 13, for example, at least approximately with a dovetail-shaped cross-section, whereby the Veran-kerungs- and connection effect between the attachment element 2 and the base body 6 can be 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 12. The same applies to the recess 10. Furthermore, this recess 12 does not necessarily have to be groove-like, but at discrete areas on the base body 6 several recesses 12 can be arranged on the front side.
    The automotive interior trim component 1 can also have other cross-sectional tapers, for example in the region of or at a trim edge. The cross-sectional taper can be designed so that the base body 6 tapers in the direction of the end face 5, that is, has a deposition. It should be noted, however, that this shape of the cross-sectional taper of the base body 6 is not restrictive. In particular, this cross-sectional taper does not have to be designed as a sharp-edged offset, but can also be provided with a rounding. There is also the possibility that the base body 6 is chamfered in the region of the trim edge.
    The deposition may preferably be formed on both opposite surfaces of the base body 6, ie on the upper side 3 and also on the underside 4 opposite this upper side 3, wherein only one of these surfaces may be provided with the offset. The deposition can be produced for example by the removal of the decorative layer 7 or 9 in this area (or by the provision of a decorative layer 7 or 9 with smaller dimensions). By deposition, there is the possibility that the attachment element 2 terminates at least approximately planar with the two surfaces of the base body 6.
    There is also the possibility that at least one reinforcing element 14 and / or reinforcing fibers (such as, for example, carbon fibers, glass fibers, natural fibers, etc.) are arranged or embedded in the add-on element 2, as indicated by dashed lines in FIG. The number and the position and the shape of these reinforcing elements 14 and / or reinforcing fibers depend on the mechanical requirements of the automotive interior trim component 1. There is also the possibility that the at least one reinforcing element 14 has reinforcing fibers.
    Dashed line is further indicated in Fig. 6 that in the add-on element 2, at least one cavity 15 may be present. By this at least one cavity 15, the attachment element 2, a reduced rigidity can be imparted, so it can, for example, contours, where it comes to rest, better shape, even if the attachment element 9 is made of a hardness ren ren plastic. In addition, it can also be used to achieve a dampening (for example, sound-damping) effect.
    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, although these embodiments are preferred embodiments of the automotive interior trim component 1.
    The attachment 2 is made with a 3D printing process of a polymeric plastic. As the polymeric plastic, a above-mentioned plastic with or without reinforcing fibers can be used. But it is also possible that the attachment element 2 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 attachment 2 to reach, or by the above-described at least one reinforcing element 14 and / or the reinforcing fibers is also made of a polymeric plastic, which is different, to the polymeric plastic of the remaining attachment 2, in particular harder or stiffer. The 3D printing method has the advantage that the different polymeric plastics can be printed in one step. However, the reinforcing fibers may also already be contained in the polymeric plastic.
    If the at least one reinforcing element 14 is provided and produced by means of the 3D printing method, a plastic material selected from a group comprising or consisting of PP glass fibers, PA glass fibers, PP carbon fibers, PP can be used as the polymer plastic for this purpose. Natural fibers, etc.
    As shown schematically in FIG. 7, after the 3D printing process on the main body 6 of the motor vehicle interior component 1 by means of a print head 16, the attachment 2 is made of the at least one, possibly molten, polymeric plastic, by placing the polymeric plastic on the base body 6 in the appropriate places (see above description) is printed. The print head 16 can be mounted on a robot 17 for this purpose. Further, the printhead 16 may be multi-dimensionally movable. Alternatively or additionally, it is also possible that the base body 6 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 16 is connected via a line 18 to at least one reservoir 19. In the storage container 19, the raw material or the polymer material from which the attachment element 2 is to be produced is kept in stock and fed to it from the print head 16.
    As indicated by dashed lines in Fig. 7, the attachment element 2 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 add-on element 2 can be produced.
    The add-on element 2 can, depending on the design of the print head 16 and / or the movement sequence, be constructed in its entirety or in sections in layers over its length.
    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. 8, the 3D printing method can be part of a production line 20 for (serial) production of the automotive interior component 1. The production line 20 can have a first station 21, a forming station 22 and a printing station in the production direction 23 comprise or consist of these. In the first station 21, the individual layers for the Fierstellung of the main body 6, so for example, the core layer 8 and the decorative layers 7, 9 or other layers corresponding to the desired layer structure superposed and optionally heated, if the base body 6 is formed multi-layered. In the following shaping station 22, this basic body 6, which is for the time being flat, can be given the desired shape in a press and, if appropriate, the individual layers can be connected to one another. It may be possible that the station 21 and the forming station 22 are combined so that the layer materials are stacked, deformed, formed and bonded together directly in the forming station 22. It is also possible that the base body 6 is already produced in its final form. The stations 21 and / or 22 may be formed or used according to the state of the art. They can be equipped with at least one trim element for the automotive interior trim component 1. Any necessary trimming can also be done in a separate tool.
    After the forming station 22, the printing station 23 follows, in which the add-on element 2 is produced with the print head 16 (FIG. 7). This printing station 23 can have a processing chamber or processing cabin in which the print head 16 and optionally the robot 17 is or are arranged. The processing chamber or processing cabin can be made closed. The printing station 23 can be arranged directly after the shaping station 22. But it is also possible that the pressure after an intermediate storage of the attachment 2 in the course of the final production (which may include quality control, etc.) takes place.
    According to a variant embodiment of this method for the production of the add-on element 2, it may be provided that the main body 6 of the motor vehicle
    Interior equipment component 1 at least in the area in which the attachment element 2 is manufactured or printed, is heated prior to the printing of the add-on element 2. In particular, the base body 6 (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 attachment 2 is made. For several plastics used, this is the temperature of the plastic melting at the lowest temperature.
    The temperature of the base body 6, for example, by means of infrared radiator, hot air, hot stamp, etc., take place.
    It can further be provided that at the beginning of the printing of the attachment 2 on the base body 6 at a first temperature and at the end with a second temperature, wherein the first temperature is usually higher than the second temperature.
    According to one embodiment variant, it can be provided that the printing of the attachment element 2 on the base body 6 takes place using a temperature gradient between the first temperature and the second temperature. The temperature gradient can be selected from a range of 1 ° C. / layer application to 10 ° C. / layer application.
    It can further be provided that the attachment element 2 is produced with a hardness gradient. The hardness gradient can be controlled, for example, by appropriate data and / or choice of material, wherein due to the data and / or choice of material, the raw material composition for the production of the attachment 2 is changed. The 3D printing device may have more than one storage container 19, in which different polymeric plastics or raw materials are contained for this purpose.
    If the attachment 2 is designed as a visible reinforcing element on a surface of the automotive interior trim component 1, this can also be designed in the form of a label.
    In addition, the superimposed printed reinforcing elements in defined areas, which are crucial for the component rigidity, can be applied. With the choice of materials, the stiffness can be influenced both at room temperature and at higher temperatures.
    With the component inscription also assembly arrows or other relevant markings in different colors can be attached to components at the same time.
    The exemplary embodiments show possible embodiments of the automotive interior equipment component 1, the 3D printing device and the production line 20.
    For the sake of order, it should finally be pointed out that for a better understanding of the construction of the automotive interior equipment component 1, the 3D printing device and the production line 20, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
