    Invention Patent Descriptive Report for "SOFT COMPONENTS MADE INDIVIDUALLY MADE TO MEASURE". The present invention relates to the design and manufacture of customized components and / or devices, in particular soft components / devices, for example, components for soft ear molds.
    BACKGROUND OF THE INVENTION Individually made-to-measure personal products are known in the art, products of low technology, as well as high technology. Examples are shoes, jewelry, hearing aid devices, dental restorations and the like. The examples mentioned are products that are more or less customized for an anatomical part of an individual to provide the best possible fit. This personalization requires a type of mapping of the individual, or at least a mapping of the specific body part. A detailed mapping can be provided by direct scanning or using prints. The impressions are widely used in dental restorative work and in hearing aid technology. When a mapping of the individual, for example, the mapping of an ear, has been provided, the methods and processes are known in the art to design and manufacture the individually customized devices, for example, through CAD technology / CAM where the only components of the device (or a prototype of the device) can be designed and manufactured to optimally fit the individual. However, this applies, in most cases, to rigid components (or prototype components) that can be directly manufactured using CAM technology. An ear mold is a device used in the ear to conduct sound or protect the ear. When used in hearing aid devices (in particular, hearing aids (BTE)) the earmold is used as a conductor, thereby improving the transmission of sound to the eardrum. For the best fit, the ear molds can be anatomically sized to the ear and the ear canal.
    For general use, ear molds can be produced in different sizes.
    Ear molds can be made of hard or soft materials, however, soft materials naturally provide greater user comfort.
    JP2006197145 discloses a method of fabricating a mounting element in the ear hole, for example, for an ear protector, which produces shape data to measure the shape of the hole in the ear in different states.
    The shapes of the ear orifice (1,2) in different states are measured and some data of the shape of the ear orifice (6,7) are generated.
    The shape data (10) is generated by a computer (8) that uses the required ear hole shape data.
    The format data produced by the computer is sent to a numerical control modeling machine (11) to manufacture the ear hole mounting element (25). The mounting state of the element is maintained in a favorable position even when the shape of the ear hole changes.
    Document KR20090092519 discloses a method of fabricating a hearing aid housing comprising: a step of taking an impression of the ear using silicone; a step of digitizing the ear impression; a step of designing the housing of the hearing aid using the computer program; a step of producing the hearing aid apparatus housing using rapid prototyping equipment; and a step of assembling the electronic components and the housing of the hearing aid and managing the quality.
    The stage of digitizing the ear impression uses a three-dimensional scanner in consideration of the complexity and diversity of the ear shape.
    US2004026163A discloses a method for manufacturing ear devices with at least one ventilation passage that extends substantially substantially over the length of said ear protection device between the regions that, respectively, face the eardrum and the external environment of the ear which comprises the steps of: providing data that include a three-dimensional shape of said ventilation passage; to build parts for said hearing devices by respectively depositing a layer of one of a liquid and a porous material, respectively and solidifying through a laser arrangement, in said layer, the individually sized layers of said parts, thereby controlling said laser arrangement with said data to solidify in said layers respectively a contour of a cross section of said ventilation passage.
    According to a modality, an auricular device is made flexural or compressible in a predetermined region.
    The housing of the hearing aid, in particular that of a hearing aid inside the ear, for this purpose, is fitted in one or more predetermined areas with a corrugated or accordion-like bellows structure, where flexibility or compressibility are required.
    WO02071794A discloses a method for computer aided modeling of personalized ear pieces comprising at least one part that is individually combined with an ear canal and / or an opening, the said method comprising the steps of: a) obtain a three-dimensional computer model, a 3D model, of at least part of the ear canal, the said 3D model having an external surface, b) initially having at least one component in relation to the 3D model, c) initially have a cutting curve or cutting surface with respect to the external surface of the 3D model, and said cutting curve or surface divides the 3D model into an external part and an internal part, d) initially forming a surface of connection that connects at least one component and the internal part of the 3D model, and said connection surface is, therefore, part of the 3D model, e) perform an assessment of the layout of at least u m component, said assessment comprising a collision detection of at least one component with respect to one or more parts of the 3D model and / or other components, and f) adjusting the arrangement of at least one component, the arrangement the cutting curve or the
    surface, and / or the formation of the connecting surface based on the result of said assessment. According to a modality, different materials are assigned to the different parts of the model taking into account the location of the rigid and soft parts of the ear canal and / or shell and / or opening. 5 US2006239481 A discloses a method for producing an impression mold for a component of the hearing device, comprising the steps of: providing CAD data representing a three-dimensional shape of a component of the hearing device; forming negative data regarding the shape of said component of the hearing device; and molding a negative mold of said component of the hearing aid from said negative data using a rapid prototyping technique.
    SUMMARY OF THE INVENTION An object of the invention is to be able to efficiently manufacture a customized soft component for personal devices. This is achieved by a computer-implemented method to create a custom CAD model of a molding mold, defined as the molding CAD model, for forming a custom device, where the molding mold is used for molding. molding of at least a partially soft shape as part of the custom device, and where the molding mold is adapted to be manufactured through rapid prototyping, such as 3D printing, the said method comprising the steps of: - purchase a 3D entry model that represents the custom device, where the 3D entry model is acquired through 3D scanning, - generate the mold mold CAD model as a print of at least a part of the input 3D model, the mold mold CAD model thereby comprising the negative geometry of the custom device, and - defining at least one sectioning of the mold CAD model molding olde by means of at least one separation plane and / or separation groove.
    In the preferred embodiment of the invention, the customized device is sized and / or sized to fit an anatomical part of the person.
    This would be the case if the personalized device was a BTE hearing aid device for a person and the component was the corresponding earmold, that is, the earmold is sized to fit the person's ear canal.
    The personalized device could also be a shell-type hearing device that comprises a soft mold part, where the hearing device can be of the receiver type in the channel (RIC), inside the ear (ITE), inside the channel (ITC) , completely inside the channel (CIC), invisible in the channel (IIC) etc.
    Thus, with the present invention a CAD process can be applied to the project and produces a soft, smooth-cased mold for the application of a hearing device or hearing aid when using a manual and / or automatic set of computations in an application. computer program to generate a mold for pouring or injection molding.
    One embodiment of the invention, therefore, discloses a way to design and manufacture individually tailored soft ear molds.
    The manufacture of soft molds can be produced by means of molding due to the fact that it is not possible to manufacture a soft mold, for example, of silicone, by means of 3D printing.
    Thus, the present invention can be used to manufacture molds that cannot be produced using other techniques, for example, 3D printing.
    A custom device, such as an earmold, can comprise either a hard or soft part, so a custom device can consist of just a soft part or comprise a combination of hard and soft parts.
    Soft can be defined as giving in to physical pressure, unduly susceptible to influence, complacent, etc.
    The 3D model of entry is preferably the starting point
    in the process of designing a molding mold, due to the fact that the 3D entry model is the model that represents the customized device.
    Thus, an object of the present invention is to provide the means and methods to provide a real physical replica of the incoming 3D model or at least a part of said 3D model.
    It is an advantage that the method is implemented by a computer instead of being performed by handicrafts, since if handicrafts are used, it is not possible to make some very small components, parts or resources in the mold, but this is possible when a computer-implemented method is used.
    Very small resources, for example, may be needed when creating a hearing device with a mold or shell for children who have very small ears.
    Furthermore, the quality and / or the manufacturing capacity that is obtained by craftsmanship may not be good enough for the customized device, such as hearing devices, where the fit or complexity of the device is very important .
    In such cases, a computer-implemented method must be used to achieve a satisfactory result.
    Another advantage of using a computer-implemented method is that it reduces the consumption of soft material as long as there is no waste.
    Some of the materials that are used to produce, for example, ear molds for hearing devices are very expensive, and therefore it is very desirable to use as little material as possible, and even, for example, 5% less material used can be very advantageous in financial terms.
    When using a computer-implemented method of creating an earmold, no material will be discharged, but when making an earmold using manual labor, for example, tubes for creating ventilation channels must be drilled afterwards of the manufactured earmold, and then this possibly very expensive earmold material will be non-reusable.
    The different styles of dies can be used when making a mold mold CAD model for, for example, an ear mold, such as: - an open shell matrix which is a simple reusable design for pouring the customized soft molds when a complex outer surface is not required; 5 - a closed matrix that is a completely closed design that does not produce joining lines.
    This matrix cannot be reused, as it is broken and opened.
    But it is profitable due to its small size of printing and minimal use of material and the need for further processing; - an assembly matrix, which is a reusable design that allows for complicated parts, but that can use more material due to the assembly structure.
    Also, the final product may require some amount of further processing to remove excess material along the seam lines.
    The 3D input model can be provided directly as input data for the design and manufacturing process, for example, through a ready-to-use CAD model.
    However, as an object of the invention refers to a custom device sized to fit a person's anatomical part, an additional embodiment of the invention comprises means for acquiring one or more 3D models of at least a part of said anatomical part , and / or a print of said anatomical part.
    The input 3D model is then preferably based on said one or more 3D models.
    In addition, said one or more 3D models can be provided through 3D scanning of said anatomical part and / or through 3D scanning of an impression of said anatomical part.
    3D scanners are known in the art.
    In a particular embodiment of the invention, the personalized device is a soft ear mold, the anatomical part is the human ear and the 3D model is a model of the human ear and / or the human ear canal and / or a model of a impression of the human ear and / or the human ear canal.
    As the manufactured soft product is individually tailored, the corresponding impression mold can be seen as a disposable impression mold. With the progress in technology and the expected future cost savings in 3D printing technology, individually made 5 molds and disposable molds make sense. As 3D printing can be a standard domestic application in the future, the methods and systems revealed in the present with regard to the design and manufacture of molds can be widely applied, for example, to toys, to various tools , design objects, kitchen and household utensils, jewelry, ornaments and / or the like. True 3D printing is limited in material selection, but impression molds and, in particular, disposable molds can open up a new variation of materials, for example, the silicone that can be applied in the forming process . The present invention is therefore, in some way, the optimization and modernization of the prior art of mold making.
    DEFINITIONS Molding Molding is a manufacturing process by which a liquid material, such as plastic, glass, metal, silicone or ceramic, is usually poured into a mold and then allowed to solidify. The mold contains a hollow cavity of the desired shape. The liquid hardens or adjusts within the mold, adopting its shape. The solidified part is also known as a mold, which is ejected or broken from the mold to complete the process. Molding materials are usually metals or various cold-setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Molding is most often used to make complex shapes that would otherwise be difficult or uneconomical to make using other methods. Modeling Modeling is the manufacturing process when dimensioning the
    foldable raw material using a rigid frame or model, so a mold can be a hollowed block.
    A mold is the opposite of a matrix.
    In the literature and in this order the terms "modeling process" and "molding process" can be used in the same sense.
    As an example, "injection molding" is, in fact, a molding process.
    In this order, the "impression mold" is the physical realization of the "impression mold CAD model". The impression mold can, for example, be manufactured on a 3D printer based on the digital input of the impression mold CAD model.
    Ear mold Unlike earmould and matrix terminology, an ear mold is a used device inserted into the ear for ear protection or sound conduction (in a hearing aid device). All BTE (behind-the-ear) and body hearing aid devices need a separate earmold.
    The earmold helps to ensure that the hearing aid remains securely in the ear.
    A well-fitted earmold helps to prevent the whistling feedback from the hearing aid by preventing sound leakage.
    The earmold must therefore fit snugly into the ear, so the earmolds must be personalized for the hearing aid user.
    An ear mold can be manufactured from an impression matrix to be an exact replica of the ear shape.
    Thus, an ear mold is not a mold in the normal sense of the word mold.
    On the contrary, an ear mold can be the result of a molding process, such as injection molding.
    When used in hearing aid devices (in particular, hearing aids) the earmold is used as a conductor, thereby improving the transmission of sound to the eardrum.
    For the best fit, the ear molds can be anatomically sized to the ear and the ear canal.
    For general use, ear molds can be produced in different formats.
    Ear molds can be made of hard or soft materials, however, soft materials naturally provide more comfort to the user.
    It is not uncommon for children to need a new earmold every 6 months or so, because as the child grows older, the earmold no longer fits properly. The present invention discloses a way to produce individually tailored soft ear molds. 5 Occlusion effect The occlusion effect occurs when an object fills the outside of a person's ear canal, and the person perceives the "hollow" or "booming" echo sounds of his own voice, because the vibrations of the sound guided by the bone are reverberating the object that fills the ear canal. When speaking or chewing, these vibrations normally escape through an open ear canal and when the ear canal is blocked, the vibrations are reflected back towards the eardrum. 3D printing 3D printing is an additive manufacturing technology where a 3D object is created by successive layers of material. 3D printers are generally faster, more accessible and easier to use than other additive manufacturing technologies. 3D printers are most often used for prototyping.
    DETAILED DESCRIPTION OF THE INVENTION The final molding mold must be an accurate negative replica of the customized device. This is provided by digitally providing an "impression" of the incoming 3D model and integrating this impression into the impression mold CAD model, which thus comprises the negative geometry of the custom device. Thus, the generation of a mold mold CAD model comprises the step of providing a negative impression of the incoming 3D model. In addition, a molding mold can comprise several parts that can be assembled as a puzzle in the modeling process and removed again when the modeling process is complete. Thus, the creation of the mold mold CAD model also comprises the step of determining the unique parts of the mold mold CAD model, that is, the separation of the mold mold CAD model in two or more sections of the mold.
    This separation can preferably be specified in the input 3D model, because the format of the input 3D model provides a good indication as to where the separation is most optimally located.
    Thus, the creation of the molding 5 CAD model additionally comprises the step of arranging at least one separation / curve / spline plane in the 3D entry model.
    This arrangement can be provided by a manual operation of the CAD user and / or by automatic arrangement, for example, based on one or more algorithms for a better fit.
    The arrangement of a separation plane and / or separation groove can also be provided to remove the lower cuts.
    In some embodiments, the method further comprises the step of providing a locking mechanism for the mold mold CAD model.
    The mold mold CAD model can provide some type of interlocking mechanism and / or lock and hold to ensure that the different parts of the mold mold fit together in a unique way and to allow tight coupling of the mold mold molding assembled.
    The locking mechanism of the mold mold CAD model is not necessarily a lock in the rigorous interpretation of the word.
    The locking mechanism, however, preferably provides some kind of assembly guide, for example, a guide for assembling the puzzle unambiguously.
    This guide can be provided, for example, by including one or more interlocking pins and / or one or more connector filaments in the mold mold CAD model.
    In some embodiments, at least one interlocking pin and / or at least one connecting filament is provided in the mold mold CAD model.
    To further assist the user in the CAD design process, a mold mold CAD model can be based on a pattern, that is, the mold mold CAD model is generated from a mold mold CAD model standard molding.
    The pattern can be a predefined pattern.
    A standard is a CAD model at least partially
    predefined.
    Thus, for example, a mold mold CAD model can be generated from a standard CAD model based on a plurality of configuration parameters.
    The standard mold mold CAD model can, for example, comprise one or more 5 patterns of single geometry and / or a plurality of interlocking geometry section models that when printed on a 3D printer can be assembled into a mold closed molding.
    Thus, in a direct design process in particular a standard mold mold CAD model is selected and after applying the negative geometry of the input 3D model to the standard mold mold CAD model the mold mold CAD model molding can be ready for printing.
    However, the actual generation of a standard mold mold CAD model may not be necessary.
    In one embodiment of the invention, the molding CAD model itself is generated from a plurality of configuration parameters.
    The configuration parameters of a mold mold CAD model and / or a standard mold mold CAD model are selected from one or more of the following parameters: - number of interlocking sections, - mold housing type of molding, such as open or closed molding mold, see, for example, figures 6 and 8, - the width of the molding mold wall, - setting of the locking mechanism, - quantity, size and location of the support struts for the impression mold, - type and location of one or more identification elements, - size and orientation of the filament (s) connector (s) between the sections of the impression mold, - dimension of the mechanism (s) ( s) locking between the mold mold sections.
    A mold mold CAD model can be additionally
    individualized when applying some kind of identification means.
    Thus, a further embodiment of the invention comprises means for defining and positioning at least one embossed or embossed identification element on the surface of the impression mold CAD model, an identification element (ID), such as a label. ID.
    Each section of the mold mold CAD model can be provided with an ID element.
    This can additionally help and guide the assembly of the different sections of the molding mold during the assembly phase of the modeling process.
    One or more ID tags placed inside or outside the molding mold surface can also provide visual and / or automatic identification of the produced part, for example, in the context of a production order.
    Thus, in some embodiments, the identification element is arranged on the surface inside the molding mold, such that the identification element will also be present in the personalized device.
    In some embodiments, the identification element is arranged on the outside surface of the impression mold, such that the identification element can be used when mounting more sections of the impression mold.
    Even if the impression mold is supplied in several separate sections, it may be necessary to break the impression mold further after the modeling process to extract the device from the impression mold.
    A further embodiment of the invention, therefore, comprises means for defining and positioning at least one surface area in the mold mold CAD model by means of lines, grooves and / or plans, said at least one area of the mold. surface adapted to act as breaking point (s) when extracting the device subsequent to the molding process.
    These surface areas can be perceived as weak and / or fragile points or lines in the printed impression mold that must break at the weak and / or fragile points or along the weak and / or fragile lines when pressure is applied (for example, merely by hand) in the impression mold.
    The shaping process necessarily involves the step of adding material to the shaping mold.
    The molding material can be arranged in one or more of the different sections of the molding mold prior to assembly and / or the molding material can be added to the closed molding mold.
    In addition, an abundance of impression material may have been added to the impression mold in the impression.
    A further embodiment of the invention, therefore, comprises means for defining and positioning at least one injection point in the mold mold CAD model, said at least one injection point being adapted for pouring and / or material injection. soft in the molding process.
    Furthermore, the means for defining and positioning at least one drainage hole in the mold mold CAD model can be understood, with said at least one drainage hole being adapted for the release of excess soft material during the molding process.
    The threading holes and / or the injection points can be positioned in the mold mold CAD model merely by manually indicating the points on the surface of the said model, that is, points where the threading holes / Injection points have entrances and exits.
    The completion of the tapping holes and / or the injection points can then be completed using CAD models predefined by such tapping holes and / or injection points.
    There may be multiple injection points and drain holes or drains arranged in the matrix.
    A ventilation duct in an earmold can reduce the sensation of a plugged ear, or in a speaking way, in a barrel.
    A further embodiment of the invention, therefore, comprises means for defining and positioning at least one ventilation channel in the mold mold CAD model.
    It may be a good idea to keep different sections of the molding mold together in the molding process.
    Thus, an additional embodiment of the invention comprises means for defining and positioning at least one securing section for a plurality of sections of the design model.
    CAD of the molding mold, said securing sections being adapted to fix the CAD model sections of the molding mold to each other, said fixing sections being preferably adapted to be breakable by hand. 5 The identification element (s), injection point (s), drainage hole (s), ventilation channel (s), surface area (s) and / or attachment section (s) mentioned above can be supplied as one or more predefined CAD models.
    For example, the clamping sections themselves are a predefined CAD model, for example, selected from a database of CAD models and integrated with the mold mold CAD model.
    In addition, the positioning and / or arrangements mentioned above can be provided manually by a user of the CAD process or automatically by the CAD computer program, for example, by the predefined placement rules, or by a combination of them.
    As the molding mold will typically be manufactured on a 3D printer, an additional object of the invention is to minimize the amount / volume of material required for the molding CAD model, both to speed up the manufacturing process, but also to to be profitable in terms of used printing material.
    An additional embodiment of the invention, therefore, comprises means to minimize the amount / volume of material required for the mold mold CAD model.
    This can, for example, be provided as a last step in the CAD design process, that is, when the mold mold CAD model is finished, an additional step may be to reduce the volume of essentially all parts of the model, either manually or automatically or a combination of them.
    Preferably, the volume of the support struts is reduced and / or minimized.
    In some embodiments, the molding mold CAD model is a molding housing CAD model that comprises a groove into which the soft material is adapted to be poured and a space retainer to provide a hollow housing.
    It is an advantage, since due to the groove and the space retainer the resulting molded part will be hollow.
    The soft material can be silicon, which provides a comfortable soft housing that can be used as a soft outer surface for a hearing device, and the rigid material can be arranged inside the soft housing, for example, to secure electronics, etc. to the hearing device.
    In addition, the molding housing CAD model can also comprise all the usual elements, such as a tube for creating a ventilation channel as part of the housing.
    A still further embodiment of the invention comprises means for grading the mold mold CAD model, such as grading along the geometric axes x, y, and / or z, and / or uniform grading of all parts.
    An additional object of the invention is to manufacture the realization of the personalized device (or merely a component of it). This is achieved by a system for producing a soft matrix for a personalized device, a device, such as an earmold for a hearing aid, said system comprising: - means for creating a mold model of mold according to with the system described herein, - means for providing a molding mold based on said molding CAD model, - means for injecting and / or pouring the soft material into the molding mold, - means for assembling the different sections of the mold, and - means for extracting the mold from the mold: - when disassembling each section of the interlocking mold, and / or - when breaking the mold along one or more fragile lines.
    Equally, the invention relates, in addition, to a method for producing a soft matrix for a customized device, a device such as a hearing aid device for hearing aids.
    cular, and said method comprises the steps of: - designing a molding CAD model according to all the steps of any of the methods described above, - printing a molding 3D based on said mold 5 mold mold CAD model, - inject and / or pour the soft material into the mold mold, - assemble the different sections of the mold mold that contain the soft material, thereby producing the soft matrix, and - extract the mold mold matrix by: - disassembling each section of the interlocked matrix, and / or - breaking the matrix along one or more of the fragile lines.
    In the actual process of producing the mold, the order of assembly and injection can vary, that is, soft material, such as silicon, can be added (for example, poured) before the assembly of the mold sections. molding or soft material can be injected after assembling the molding mold.
    The molding mold can be realized through the rapid formation of prototypes.
    However, 3D printing is the preferred manufacturing process for the molding mold.
    A further embodiment of the invention comprises means for aligning the impression orientation of the impression mold manually or automatically or a combination of them.
    The invention further relates to a computer program product provided with a computer-readable medium, said computer program product providing a system for creating a custom CAD model of a molding mold for molding of a personalized device, and said computer program product comprises means for performing all steps of any of the methods listed herein.

    DETAILED DESCRIPTION OF THE DRAWINGS Figure 1 illustrates an example of the process based on the CAD modeling computer program to create a mold molding CAD model for a hearing aid device. A 3D model of an impression of the ear canal 11 is the basis for the design of the incoming 3D model 12, which is a hearing aid device for BTE earmold (or at least part of it) individually designed for fit the ear represented by the 3D model 11. This part of the process is known in the art and usually a rigid ear mold would be manufactured from model 12, or possibly a 3D prototype of model 12 could be manufactured on a 3D printer and a soft ear mold could be (manually) formed to look like the prototype model.
    However, according to the present invention, a mold mold CAD model 14 can be created "around" the entry model 12. A mold mold that corresponds to this mold mold CAD model 14 can then be manufactured, for example, through rapid prototyping or through a 3D printer, and a soft ear mold that is an exact replica of the entry model 12 can subsequently be supplied in a molding process using the molding mold.
    The mold mold CAD model 14 can be designed with the optional input of a database 13 of predefined mold pattern patterns, patterns which can be single geometry patterns and / or a sequence of geometric sections with optional locking mechanisms between them.
    The mold mold CAD model 14 comprises three 15, 16, 17 which when manufactured can be assembled in a unique way in a closed mold mold, that is, exactly like a 3D puzzle or a mold kit. Assembly.
    Figure 2 illustrates a 3D model of input 21 for a hearing aid with ventilation channels 22 and ID tag 23. In figure 3, a separation plane 33 is applied to the 3D model of input 21 that separates the model 21 in two parts: an internal part 31 and an external part 32. This separation plane 33 also determines the separation of the impression mold that must be created to provide the physical realization of the incoming 3D model 21. The separation 33 can be automatically arranged to provide the most appropriate separation of the entry model 21 in terms of lower cuts, etc.
    The separation plane 33 can preferably also be arranged by the user of the CAD computer program, that is, the creator of the mold molding CAD model.
    The separation plane 33 can be edited in terms of, for example, position and angle.
    The separation plane 33 can preferably be edited at any time during the creation of the 3D model mold.
    The illustrated separation plane 33 is a 2D plane, however, the separation of the incoming 3D model can be any curve or groove that defines a separation of the incoming 3D model.
    Area 34 is a segment of the separation plane 33 that is visible because the separation plane cuts through the entry model 21 at the location of a depression in the entry model 21. Thus, in a CAD model design process of actual impression mold the slope and / or location of the separation plane 33 would be adjusted for practical purposes to prevent this segment 34 from cutting through the entry model 21. A more advanced separation method is illustrated in figure 12 which is almost equivalent to figure 3 with a separation plane 33 applied to the 3D model of entry 21. In this case, a guide line 33 'is added to the separation plane 33 to illustrate more clearly the separation of the entry model 21 A frame 35 is added to indicate the size of a corresponding mold mold CAD model, that is, when changing the size of frame 35 the size of the corresponding mold mold CAD model is changed accordingly.
    Line 36 indicates a second separation from the input model 21 which is thus separated into three parts.
    The corresponding mold mold CAD model then comprises, in an equivalent manner, three mold sections.
    A separation plane for the second separation along line 36 is not indicated in the drawing, however, the second separation of the input model 21 could, for example, be applied along a 2D plane substantially perpendicular to the plane line 33 and along line 36. Figure 4 shows a mold section 41 of the mold mold CAD model that corresponds to the inner part 31 of the inlet model 21. The mold section 41 therefore comprises the negative geometry of the inner part 31 and the separation plane 33 determines the top covering surface for the mold section 41. The mold section 41 is part of a type of mold mold that can receive the term "mold negative open molding ". The tubes 42 for creating the ventilation channels 22 are also visible.
    The width of the wall of the mold section 41 is indicated
    by the arrows 43. The width of the wall 43 should be chosen as thin as possible to minimize the cost and time to manufacture the molding mold, however, strong enough to support the modeling process. 5 Figure 5 is another perspective view of the mold section
    41. A fragile line / curve 51 is visible. This fragile line / curve is designed on the CAD model to be a part of the mold section 41. The fragile line 51 will become a weak point after the modeling process, that is, the molding mold will be easy to break when along the brittle line 41 when the die is separated from the impression mold. Figure 6 shows a perspective view of a mold mold CAD model 61 according to an exemplary embodiment of the invention. The CAD model 61 comprises three sections of the mold 63, 64, 65 that fit together by means of locking mechanisms. The mold sections 64, 65 are combined together by means of the tongue and groove connections 66, 66 '. The notch 67 is compatible with the 67 ', the notch 69 is compatible with the 69', the notch 68 is compatible with the mounted connections 66 and, correspondingly, the notch 68 'is compatible with the mounted connection 66', thus , the 3D model of the open mold mold 61 can be mounted on the closed mold mold CAD model 62. The support struts 71 are provided as a support structure and the locking mechanism is also part of the support struts for highlight the tight coupling of the mounted molding form. The support structure can provide a thinner molding wall and thus use less material for the molding mold. The support struts 71 further guarantee that the assembled molding mold supports the application of pressure during the modeling process. The negative printout of an ID 70 tag is also visible. Figure 11 is a larger illustration of the closed mold mold CAD model 62. Figure 7 also shows the mold mold CAD model 61 with closed filament connector planes 72, 73 between the different mold sections 63 , 64, 65. Connector filaments 72, 73 can
    breakable, thereby simplifying the assembly of the die, as they provide a guide for assembly.
    The molding mold can then be printed on a piece where the different mold sections 63, 64, 65 are connected by the connecting filaments.
    In this way, a single order (for example, a single impression mold) can be kept together after printing.
    During the shaping process, the mold sections 63, 64, 65 are separated by breaking the connecting filaments 72, 73 where the now separate molding sections 63, 64, 65 can be mounted on the closed molding mold 62. The connector filament 73 is a very simple connector filament that merely provides a straight connector filament connection between the two sections of mold 63, 64. However, connector filament 72 is flexed in a semicircle.
    The reason is that a straight connector filament between the two sections of the mold 64, 65 would have to be located on the surfaces of the mold sections 64, 65 that are joined.
    When placing a connector filament in a semicircle 73 on the surfaces of the mold sections 64, 65 that are not joined in the molding process a tight coupling between the mold sections 64, 65 is guaranteed in the molding process because the joined surfaces are kept as flat and smooth as possible.
    Yet another type of mold mold CAD model 81 is illustrated in figure 8 with two mold sections: an upper section 82 and a lower section 83. The separation plane applied to the corresponding 3D input model determines the separation between the two mold sections 82, 83, that is, the upper surface of the mold sections 82, 83. The mold section 41 therefore comprises the negative geometry of the inner part 31 and the separation plane 33 determines the surface of opening from the top to the mold section 41. The mold mold CAD model 81 is a type of mold mold that can receive the term "closed mold mold". The interlocking of the two sections 82, 83 can be provided through the compatible corners 84, 84 '. Indentations 86, 86 ', 86 "are provided for easier separation of the two sections 82, 83 after the modeling process.
    The support struts 85 are provided as a support structure for the mold mold 81. The support struts 85 provide the use of less material for the mold mold 81 compared to an almost all solid cube.
    However, it is seen that although the support struts 85 are provided, the type of molding illustrated in figure 8 requires more material than the type illustrated in figures 6 and 7. On the other hand, the type of impression mold in figure 8 may be easier to design, because the basic building blocks of the impression mold CAD model 81 can be supplied from the standard impression mold CAD models.
    A CAD model of mold mold 91 with three sections of the interlock mold 92, 93, 94 is illustrated in figure 9. The complex shape of the corresponding entry model required the use of the three mold sections to obtain a complete replica of the model input.
    The interlocking corners 95, 95 'are compatible, just as the other two corners 96, 96' fit together.
    Figure 10 shows a closed triangular plan view of the mold section 101 of a mold mold CAD model.
    In this illustration, the preferred orientation of the geometry axes is indicated with the directions of the geometry axis x 102 and the geometry axis z 103. A connector filament 104 and a part 105 of a locking mechanism are also visible.
    In the preferred embodiment of the invention, any changes to the separation of the input model are instantly reflected and updated in the corresponding mold mold CAD model.
    That is, the 3D input model and the mold mold CAD model are systematically interrelated.
    When designing and creating a mold mold CAD model according to the invention the user of the CAD modeling computer program can be confronted with a plurality of configuration parameters that specify the mold mold CAD model - dosage.
    The configuration parameters can be:
    - numerous sections of the separate interlocking matrix - method (s) of separation of the CAD input model, defined as one or more planes or grooves - configuration of the locking and fastening mechanisms between the matrix sections - a matrix wall width - configuration of the connectors between each section of the matrix separated when printing the matrix assembly - grading the matrix along the geometric z axis - configuration of the struts to support each section of the matrix to support the general matrix when assembled - placement of the ID tag in each section.
    Figure 13 shows an example of a CAD model of the matrix housing.
    The CAD model of the matrix housing 131 comprises a groove 133 into which the soft material, such as silicone, can be poured.
    This will result in a personalized hollow housing instead of a more or less filled ear shape, because due to the groove 133 and the space retainer 134 the resulting formed part will be hollow.
    The CAD model 131 comprises a tube 132 for creating a ventilation channel as part of the housing.
    The soft housing can be used as a soft outer surface for a hearing device, and the rigid material can be arranged inside the soft housing, for example, to hold the electronics etc. to the hearing device.
    Figure 14 shows an example of a closed-type CAD model with an injection point and drain.
    The CAD model 141 comprises an injection point 145 and a drain 146 which is a small hole in the bottom of the CAD model 141. There may be multiple injection points 145 and drains 146 arranged in the matrix.
    The injection point 145 can first be defined and then positioned on the mold mold CAD model 141, and the injection point
    tion 145 is adapted for pouring and / or injecting soft material into the molding process.
    The drain or drain hole 146 can first be defined and then positioned on the mold mold CAD model 141, and drain hole 146 is adapted to release excess soft material during molding process.
    The drain holes 146 and injection points 145 can be positioned in the mold mold CAD model by manually indicating the points on the surface of the model 141, that is, the points where the drain holes 146 and the injection 145 have inputs and outputs.
    Completion of drain holes 146 and injection points 145 can then be completed using predefined CAD models for such drain holes 146 and injection points 145. There may be multiple injection points 145 and drain holes. or drains 146 arranged in the matrix.
    In addition, the mold mold CAD model 141 was individualized by applying an identification element (ID) 147 which is the numbers "123". The ID 147 element has been defined and positioned as an embossed or notched identification element on the outside surface of the mold mold CAD model 141. Each section of the mold mold CAD model 141 can be provided with an element ID 147. One or more ID tags placed inside or outside the molding mold surface can also provide visual and / or automatic identification of the produced part, for example, in the context of a production order.
    In this case, the identification element 147 is arranged on the outside surface of the impression mold, such that the identification element can be used when more sections of the impression mold are assembled.
    In other cases, the identification element 147 can be arranged on the inside surface of the molding mold, such that the identification element will also be present in the personalized device after molding.
