In particular, if necessary, a side wall beaks outward in the shape of a beak when the bottom region of the trough is bent. Through the formation of the beak-shaped bulge, a targeted dumping of the mass in the tub can be made possible.
    Optionally, the trough comprises one or more dividers such that two or more sub-troughs are formed. For example, two sub-wells can be formed by a single divider. For example, in the two separate sub-wells, different masses may be arranged to form objects of different masses. Optionally, there are a plurality of dividers so that a plurality of laterally separated part-troughs are formed. In the sub-pans different masses or the same mass may or may not be arranged.
    The dividers may be integrally connected to the trough or be part of the trough. Optionally, the dividers are subsequently inserted webs. If necessary, the dividers are subsequently inserted webs, which are positively or stoffschlüssig connected to the tub or are, and in particular glued or welded to the tub.

    Base body to the outside. Optionally, in all embodiments, the base body may be a part of the object or a part of the product to be formed.
    Optionally, in all embodiments, the interior of the housing, the ground, the base body, the interior of the second housing part, and other components of the system may be heated or heated. For example, radiators, in particular radiant heaters, IR radiators or inductive heating devices, etc., may be provided as the heating device. Optionally, the base body can also be heated. Optionally, these emitters are directed inside the housing to the mass 2 and in particular from below to the mass. Optionally, the emitters are directed from above onto the mass. Optionally, a radiator or a plurality of radiators are connected to the holding device, so that they can preferably be moved with the holding device. Optionally, however, the heater is also a heating element that delivers heat to the housing interior via artificial or natural convection. By heating the mass, in particular, its consistency, for example its viscosity, can be changed in order to optimize the build-up process of the object. In particular, the adhesion tendency of the mass to the tub can also be optimized.
    Optionally, the tub is made by an injection molding process. In particular, the tub and optionally the dividing elements and the sub-tubs are manufactured as a single tub body, which is formed in particular by an injection molding process and / or an embossing process. Preferably, the tub is formed of an elastic material. In particular, this material is or contains silicone.
    Optionally, the movement device is designed so that a substantially free accessibility of the tub from the outside, with lifted second housing part, is made possible. In particular, the elements of the moving device are rod-shaped and narrow, so that free surfaces are provided between them, whereby the handling of the internal elements of the device is facilitated. Thus, for example, during the construction of the object, the second housing part can be removed, for example, to observe the construction progress or umeine To refill mass in the tub.
    The invention will be further described below with reference to the figures and by means of specific embodiments.
    Figures 1a, 1b and 1c show oblique views of a system according to the invention from outside in different positions. Fig. 2 shows an oblique view of the system according to the invention, with some components, in particular parts of the housing, being hidden. Figures 3a, 3b and 3c show three different positions of the system according to the invention, with parts of the housing and the base as well as other components hidden. Fig. 4 shows several views of possible configurations of a tub and a base body. Fig. 5 shows details of a tub. Fig. 6 shows a possible embodiment of a base body and in particular a slide. Fig. 7 shows several views of a system according to the invention comprising a handling device. FIG. 8 shows a further embodiment of a base body according to the invention or a slide according to the invention.
    FIGS. 1a, 1b and 1c show an embodiment of a system according to the invention comprising a main body 3 and a housing 8. The housing 8 is made of several parts. In particular, the housing 8 comprises a first housing part 12 and a second housing part 13. On the housing 8 and / or on the main body 3, as shown in this embodiment, a display device 24 and / or one or more operating elements 25 may be provided. The display device 24 may be formed as a conventional display device such as an LCD display device. Optionally, the display device is also a touch-sensitive display device and in particular a touch screen. In one embodiment of the display device 24 as a touch screen, the display device 24 itself is also a control element 25. If necessary, however, a self-contained control element 25 is provided. Such controls may, for example, allow for control of the system according to the invention.
    The main body 3 is preferably arranged stationary and can be parked, for example, on a solid surface such as a table or a floor. The main body 3 is surrounded by a housing 8 at least partially, preferably completely. Optionally, openings 8 are provided in the housing 8, for example for the inlet and outlet of cooling air or for plug connections. The base body 3 is optionally surrounded by a first housing part 12 or integrally connected to a first housing part 12. Furthermore, a second housing part 13 is provided. This second housing part 13 is preferably designed in such a way that, together with the first housing part 12, the housing 8 completely surrounds and thus forms a substantially closed housing 8. The second housing part 13 preferably has one or more housing openings 20.
    Preferably, the housing openings 20 or the housing opening 20 are closed executed. The closing of the housing opening 20 is done, for example, by a lid that completes the shape of the housing 8 or the housing 8.
    Furthermore, a base body 6 is provided. This base body 6 is used in particular to the An- or construction of the object to be formed 1. Preferably, the base body 6 from outside the housing 8 is accessible, removable or removable. In particular, the base body 6 extends from the outside into the housing 8. In this case, as in the present embodiment, different sized housing openings 20 may be provided. The base body 6 is preferably held by a retaining device 7 which is not visible in this illustration. The holding device 7 is formed according to a preferred embodiment of a moving device 10 - also not visible - against the base body 3 movable. Via the movement device 10, the system according to the invention can be brought from a first position 15, as shown for example in FIG. 1b, into a second position 16, as shown for example in FIG. 1a. Between the first position 15 and the second position 16, the holding device 7 sets a path 17 back. The path 17 taken in the formation of an object corresponds approximately to the height of the formed object.
    Optionally, or according to the present embodiment, the second housing part 13 is coupled or connected to the holding device 7. When moving the holding device 7 via the movement device 10, the second housing part 13 is also moved. The housing 8 is thereby made extendable or telescopically extendable. In the present embodiment, the housing 8 is box-shaped. The first housing part 12 has a slightly smaller outer dimension than the internal dimension of the second housing part 13. As a result, the second housing part 13 can be slipped or pushed over a part of the first housing part 12 in a box-shaped manner. It goes without saying, however, that the first housing part 12 is slightly oversized with respect to the second housing part 13, according to the invention.
    In particular, in all embodiments, the overlap distance 19 is in particular that distance by which the two housing parts overlap, for example the distance between the lower edge of the second housing part 13 and the upper edge The overlap distance runs in particular along the direction of movement of the relative movement of the two housing parts 12, 13. The overlap distance 19 of the first position 15 in the present embodiment is greater than the overlap distance 19 of the second position 16. In both positions the two housing parts 12 and 13 overlap one another, so that the housing at any time, and / or in any operating position, is formed substantially closed. Preferably, the overlap distance 19 of the housing in the first position 15 is greater than the traversed W eg 17 for the formation of the object.
    An advantage of the extensible housing parts is that the system according to the invention can be brought together to a small pack size. As a result, in contrast to rigid housings, the size of the system according to the invention can be reduced. A further advantage of the embodiment of the housing and the holding device according to the invention is that the base body 6 can extend outwards or that the base body 6 can be directly accessible or removable from the outside. As a result, the object 1 to be formed and / or the base body 6 can extend outward regardless of the space within the housing 8. As a result, objects 1 may be formed that would not in principle fit into the housing 8 from their external dimensions.
    Further, base bodies 6 to which the object 1 is attached may also be used. These base bodies 6 can likewise be designed largely independently of the housing size, since the base body 6 can protrude through the housing 8 to the outside.
    In particular, this translatory movement is a parallel displacement of the holding device 7 relative to the base body 3. Preferably, the direction of the movement is substantially perpendicular to the environment.
    The two housing parts are preferably designed box-shaped, wherein the second housing part 13 is optionally hood-shaped and is downwardly open, so that the second housing part 13 may extend around the base body 3 and in particular around the first housing part 12 around. Preferably, the second housing part 13 has a peripheral end edge, which extends substantially horizontally, for example in the lower region.
    1c shows a system according to the invention with the base body 6 lifted away. A trough 9 is provided below the housing opening 20. In the trough 9 there is a mass 2 in the ready position. In the first position 15, at least part of the base body 6 is immersed in the mass 2 or applied to the mass 2. By selective solidification of the mass 2 in the region of the base body 6, the object 1 can be grown on the base body 6. The base body 6, as in the present embodiment, may be formed as a pure slide, which is not part of the object or product to be formed. In this case, the object 1 to be formed after formation is detached from the base body 6 formed as a slide. Optionally, however, the base body 6 itself is an object 1 formed by the system according to the invention. Optionally, the base body 6 is a part of a product, the object 1 being grown on the base body 6.
    The base body 6 can, as can be seen in the present embodiment, extend outside the housing or outwards and is therefore only slightly limited in size and shape.
    Fig. 2 shows an oblique view of a system according to the invention, wherein parts of the housing 8 are hidden or removed. In particular, the second housing part 13 is hidden or removed. Optionally, the second housing part 13 is removably connected or coupled to the retention device so that by simply removing the second housing part 13, for example by lifting it up, internal components of the system are accessible.
    The first housing part 12 surrounds or optionally forms the main body 3 of the system. Furthermore, a holding device 7 is provided. The holding device 7 is connected or coupled via a movement device 10 with the main body 3. The moving device 10 in the present embodiment comprises a plurality of members through which the mobility of the holding device 7 with respect to the base body 3 is enabled.
    On the base body 3 or connected to the base body 3, a trough 9 is arranged. In the trough 9 is preferably located in its operative position a mass 2 or more masses 2.
    Figures 3a, 3b and 3c show a system according to the invention in different positions, wherein in the views of Figures 3a, 3b, 3c the base body and the housing are hidden. Other components, such as the power supply or the display device 24 are hidden.
    Figures 3a, 3b, 3c show parts of the system according to the invention, in particular a holding device 7 in a first position 15 and a second position 16, a radiation source 4, a movement device 10, drives 11, guide devices 21, a trough 9 with one in the trough 9 intended mass 2.
    FIG. 3 a shows the components in a first position 15, wherein the base body 6 is held by the holding device 7. The base body 6 optionally extends outwardly as in the previous embodiments. In particular, the base body 6 is formed as a slide in the present embodiment. He preferably has an outwardly facing handle. However, in all embodiments, instead of a base body 6 formed as a slide, a base body which is a part of the object to be formed or a part of the product to be formed may also be provided in all embodiments.
    To bring the device from the first position 15 to the second position 16, a drive 10 is provided. In particular, two drives 10 are provided in this embodiment, which preferably spaced apart on the one hand on the base body and the other hand on the holding device 7 attack. In particular, the drives 11 are designed as linear drives. By actuating the actuator or drives 11, a relative movement of the holding device 7 relative to the main body is effected. In the present embodiment, the two drives 11 are arranged on opposite sides of the holding device 7 and the base body 3, respectively.
    Furthermore, the movement device 10 preferably comprises guide devices 21. These guide devices 21 comprise, for example, elongate guide elements which are guided, for example, by bushes.
    In the present embodiment, a plurality of guide devices 21 are provided at a distance from each other. In particular, the spacing from one another causes tilting of the guide devices to be avoided. Optionally, the guide devices 21 are provided on opposite sides of the holding device 7 and the base body 3, respectively. Preferably, three or four guiding devices are provided on the outer side edges or corners of the holding device 7 or of the main body 3.
    Optionally, it is provided in all embodiments that the holding device 7 comprises a frame-shaped component 38, in particular a frame 38 having an exemption 39 through which the trough 9 is preferably horizontally feasible and connectable to the base body 3. As a result, a trough 9 filled with a liquid mass 2 can be introduced from above into the housing, without the liquid being released. Optionally, it is provided that the second housing part 13 is held by the frame-shaped component and optionally moved, and that the base body 6 of the holding device 7 and / or the housing 8 is held.

Preferably, the holding device 7 is guided parallel to the base body 3. In this case, the second housing part is preferably also displaced by the same path 17.
    Furthermore, the embodiment according to FIG. 3 comprises a radiation source 4. This radiation source 4 is designed, for example, as a projector. The radiation source 4 is preferably arranged such that it can be moved or moved via one or more radiation source drives 26. The movement of the radiation source takes place in particular in a plane parallel to the layer of an object 1 to be formed. This is preferably a horizontal plane. Optionally, two radiation source drives are provided, over which a radiation source can be moved in two directions. These two directions are in particular normal to one another, so that an x-y displacement of the radiation source 4 in a plane parallel to the object layer is made possible.

    Fig. 3b shows the same device as Fig. 3a, wherein in Fig. 3b, the base body 6 is hidden or removed. The illustrated parts of the device according to the invention are in the first position 15.
    3c shows parts of the device according to the invention in the second position 16. In this position, the holding device 7 is displaced relative to the base body 3 and opposite the first position 15 by a distance traveled 17. This displacement occurs via the actuation of the drive or drives 11. The displacement of the holding device 7 also results in a displacement of the holding device relative to the tub 9. This displacement can be effected stepwise. In particular, the holding device can be stopped in a number N intermediate positions lying between the first and the second position. By stepwise moving the holding device relative to the trough and / or with respect to the base body and simultaneous or timed activation of the radiation source 4, a layered structure of an object 1 can take place. Preferably, the radiation source emits the radiation in the intermediate positions in which the holding device is in the rest position (s). Furthermore, the radiation 5 is also shown schematically, as it may be provided in all positions and embodiments. Also, the bottom 14 of the tub may be located at all points in this embodiment.
    4a, 4b and 4c show different possible embodiments of the trough 9. Fig. 4a shows a trough 9 according to the invention, which is formed substantially as a continuous trough. Connecting elements 27 are provided in the edge region of the trough. Furthermore, the trough preferably comprises one or more handles 28. The connecting elements 27 of the trough 9 are in particular adapted and arranged to be connected to the system according to the invention or to the base body. The connecting elements 27 may, for example, be parts of the trough and optionally recesses in the edge region of the trough. Optionally, the connecting elements 27 comprise further elements, such as rigid plates or additional bodies, which are particularly suitable for improving the stability or the manageability of the trough.
    Fig. 4b shows a trough 9, in which a separating web 22 is provided. In the present embodiment, two sub-wells 23 are formed by the separation land 22. The two sub-wells 23 are separated by the divider 22. In particular, a lateral, horizontal separation is provided so that two different masses 2, one mass 2 in the first sub-well and another Mass 2 is provided in the second part of the tub, not automatically mix together and / or are separated.
    Fig. 4c shows a further embodiment of a trough 9, in which a plurality of dividers 22 are provided. In particular, eight sub-wells 23 are formed by the dividers 22 in this embodiment. It goes without saying that in all embodiments of the invention, by suitable choice of the separating webs 22, an arbitrary number of sub-wells 23 can be formed.
    Optionally, the dividers 22 of all embodiments are formed as subsequently inserted dividers. These may for example be materially or form-fittingly connected to the trough 9 to form sub-troughs 23. Optionally the dividing webs 22 are integrally connected to the trough 9 and, in particular, formed as a part of the trough.
    Optionally, the tub 9 is at least partially formed of an elastic material. Also, the dividers 22 may be formed in all embodiments of an elastic material. Also, any adhesive through which dividers 22 may be connected to the trough 1 preferably has some elasticity to ensure the elasticity of the entire trough, and in particular the splices.
    Fig. 4d shows a possible embodiment of the base body 6. In particular, this base body is adapted to cooperate with the trough 9 of Fig. 4c. However, this base body 6 is basically also suitable for being inserted with the troughs 9 of the figures 4a and 4b.
    The base body 6 shown in Fig. 4d has a plurality of extensions 29. The extensions 29 preferably extend parallel to each other from a base plate of the
    Base body 6 to the outside. In the operative position, the base body is held by the holding device or applied to the holding device. The extensions 29 protrude in this operational position in the direction of the trough and in particular in or on the mass 2. Preferably, the extensions 29 are laterally exposed. This has the advantage that when immersing the extensions 29 of the base body 6 less mass 2 must be displaced, as if a body formed over the entire surface is immersed in the mass 2. Thereby, the mounting of the object 1 to the base body 6 is improved and facilitated. Optionally, in all embodiments, the base body may also be smooth or wedge shaped towards the ground.
    Optionally, the extensions 29 are arranged in groups. These groups of extensions 29 are preferably spaced from one another and, in particular, spaced laterally apart. Preferably, the groups are spaced apart from each other so that the dividers 22 of the tub 9 can protrude into the space between the groups. Thereby, in the embodiment of Fig. 4d, in combination with the trough of Fig. 4c, in a working method eight different objects can be formed from possibly eight different masses. In a combination of the base body 6 with the trough of Fig. 4b, for example, several objects can be made of two different masses.
    Optionally, a handling device 30 is provided, in particular according to FIG. 7, which enables a displacement of the base body 6 with respect to the trough 9 or with respect to the base body 3. Depending on the design of the handling device, this displacement can take place in all spatial directions. As a result, a group of projections 29, for example when the base body is rotated by 180 ° about a substantially vertical axis, come into contact successively with different masses and thus form one or more objects 1 of a plurality of masses.
    5 shows a detailed illustration of a possible embodiment of a trough 9. The trough 9 comprises a plurality of separating webs 22, which are integrally connected to the base body of the trough 9. Partial trays 23, in this embodiment in particular eight sub-trays 23, are provided by the separating webs 22. If necessary, different masses 2 can be arranged in the different sub-troughs 23 in order to be able to form objects 1 from different masses 2.
    The present embodiment of the trough 9 according to FIG. 5 comprises connecting elements 27. The connecting elements 27 may, for example, be made more in part. Preferably, the connecting elements 27 comprise free positions 31. These clearances 31 are in particular adapted and / or suitable to be connected to elements of the basic body. Via the connecting elements 27, the connection of the trough to the base of the device takes place. Optionally, the connecting elements, which are arranged on the base body, and which are arranged in the connecting elements 27 of the tub engagement, movably, so that, if necessary, a tensioning of the tub, a buckling of the tub or a relaxation of the tub via movement of the connecting elements of the base body can take place.
    Optionally, the connecting elements 27 have magnetic or magnetizable elements 32. These elements 32 are particularly adapted to allow easy connection of the tub to the base. Thus, the tub can be connected, for example, by simply placing the top of the body. Magnetic forces can then be used to hold the tub on the base body.
    The reliefs 31 preferably extend vertically from below into the side regions of the tub. Optionally, the exemptions 31, however, also undercuts, for example, extend substantially horizontally in the tub material. Thus, for example, via hook elements, a further locking of the tub made against the main body.
    In particular, the trough 9 should be secured against lifting upwards. This happens preferably via magnetic forces, undercuts and / or hook elements, in particular via positive-locking elements or optionally over-frictional connections.
    FIG. 6 shows a further possible embodiment of the base body 6. The base body 6 in turn comprises extensions 29. The extensions 29 are preferably directed downwards and more preferably towards the mass 2 of the trough 9. In this embodiment, the base body 6 comprises a reservoir 33 for receiving a mass 2 or a substance for admixture with the mass 2. Optionally, a plurality of separate reservoirs may be provided. A base body with a reservoir may optionally be provided in all embodiments.
    The reservoir 33 is optionally connected via supply openings 34 to that area of the base body 6 in which the extensions 29 are arranged or in which the object 1 is formed. Via this additional reservoir 33 and in particular via the supply openings 34, a mass 2 or a substance can be conducted from the rear side of the base body into that region of the base body 6 in which the object is to be built or grown. This can be achieved, for example, that the spaces between the extensions 29 are filled with the mass 2 or at least partially filled. As a consequence, the base body 6 does not have to be immersed in the mass, but it is sufficient that these are applied to the mass. Thereby, the displacement of the mass 2 in the tub 9 can be further reduced.
    Optionally, the reservoir is configured such that the base body is hollow at its upper side or has a cavity. Optionally, an additive for the mass 2 may be provided in the reservoir. This additive may, for example, be or contain a dye, in particular color pigments, one or more fillers and / or one or more additives. Thereby, during the formation of the object, the consistency or the composition of the mass, in particular of the mass in the tub, can be changed. For this purpose, in all embodiments in the feed openings 34 or in the feed opening 34, a controllable or controllable valve may be provided. By controlling the valve, the supply of the substance or mass in the reservoir can be controlled. For example, this substance can be introduced dropwise into the mass. Optionally, a spray head is provided so that the substance provided in the reservoir can be atomized onto the mass or onto the object.
    Optionally, a movable element may be provided in the tub that removes or shoves the mass in the tub. In a further step, a further, second mass may be supplied via the feed opening or the feed openings, which optionally differs from the first mass.

The handling device 30 is in particular adapted and / or suitable to move the base body 6 in a desired manner via a suitable control. For example, the handling device 30 may be formed as an exchange device. In particular, in this embodiment, the handling device 30 is adapted to remove a new, second base body 6 from a tray or a magazine and with the holding device to connect or couple. As a result, several objects 1 can be automatically formed on several base bodies.
    Optionally, the handling device 30 is adapted and / or adapted to apply a (single) base body 6 in different positions to or on the device of the invention, or to connect the base body in different positions to the device. For example, the base body can be rotated and / or offset.

Optionally, the base body 6 and the handling device 30 have a common base plate via which the centering of the handling device 30 relative to the base body 6 takes place.
    FIG. 7 shows a device according to the invention in two different positions. The handling device comprises an arm 35 which is movably arranged. In particular, the arm 35 is movably arranged opposite to the base body 3 so that a base body 6 can be removed or moved.
    Preferably, the control of the handling device 30 is connected to the control of the device for forming the object 1, connectable or formed as a single control.
    Optionally, the connection of the control is made by merging the base 3 and the handling device 30 automatically. Optionally, the handling device 30 is designed as a changer system. This may optionally be part of the system according to the invention and / or with the
    System combined. Due to the accessibility of the base body from the outside, it is possible for the base body including the object formed to be removed automatically and, if appropriate, for a new base body to be supplied.

The base body 6 comprises a plurality of extensions 29. The extensions are suitable and / or adapted to grow or build up an object 1, in particular from several layers 18. In order to facilitate removal of the object 1 from the extensions 29 or from the base body 6, a separating element 36 is provided. This separator 36 is preferably disposed in the space between the projections 29 prior to the construction of the object. Now, if the object 1 attached to the extensions and in particular at the projecting ends of the extensions 29, so the partition member 36 is located between the object 1 and a base plate of the base body 6. In order to separate the object 1 from the base body 6, the separating element 36 in the extension direction of the extensions 29 are moved. Thus, a force can be exerted between the object 1 and the base body 6 by the separating element 36 in order to release the adhesion along the joining surface between the object 1 and the base body 6. This brings with it advantages, since a non-destructive removal of the object 1 from the base body 6 is facilitated. In the present embodiment of Fig. 8, the separator 36 is formed as a latticed body. This lattice-shaped body comprises a plate-shaped basic structure in which raster-shaped clearances are arranged. The exemptions are in particular arranged as passage openings which pass through the plate-shaped basic structure. The exemptions of the separating element 36 have, in particular, the same shape or arrangement as the extensions 29 of the base body 6 used together with the separating element 36. As a result, the extensions 29 can be passed through the clearances in the separating element 36.
    In principle, however, any construction of a separating element 36 for improving the device according to the invention, in which it is possible to arrange the separating element 36 between the base body 6 and the object to be erected, is suitable. Such a separator may be provided in all embodiments.
    Optionally, the separator is integrated as a perforated grid in the base body or applied to the base body. In this case, the separating element may be connected to the base body by magnets or the like during the formation of the object. After the printing process, by drawing off the separating element or the perforated grid, it is possible to apply surface pressure from the rear side of the object. This allows the object (s) to be released more gently from the base body.
    In particular, in combination with a handling device, this can be an automated separation of the object from the base body. For example, an object could thereby be automatically separated from the base body and stored, if desired, in a container. This can be done by mechanical Zugan the separator. Optionally, the handling device itself has a separating element, which is suitable by its geometry to engage in openings of the base body in order to release the parts by surface pressure.
