    [0003] FIELD OF THE TECHNIQUE
    [0004] The present invention is framed in the area of three-dimensional printing technology and, in particular, in the field of cooked food printing technology.
    [0005]
    [0006] STATE OF ART
    [0007] Three-dimensional printing has advanced greatly in recent years and many techniques have been created to print three-dimensional objects. Three-dimensional printing involves the creation of objects by superimposing successive layers of the material. There are three more common 3D printing manufacturing methods, including stereolithography (SLA), sintered selective laser (SLS) and fused deposition method (FDM).
    [0008]
    [0009] In US9321215B2 a 3D printing machine is described that allows three-dimensional printing of structures in vertical orientation. Products are printed directly from data handled by a computer that reproduces accurately, in a short time, using a fully automated process. More precisely, it describes the dispensing of a photocurable substance on a transparent substrate, the selective curing and solidification of said materials and the recovery of the solidified product.
    [0010]
    [0011] In the patent application US20160135493A1 a 3D printer system for printing a product using different materials in a process defined by a set of instructions is described, in which each of the materials is contained in a capsule and has different parameters and rheological properties. associated to it. Those parameters are what determine how the printer will handle each material contained in them.
    [0012]
    [0013] The way in which the printing material acquires the viscosity necessary to be extruded by the nozzle and then, once deposited on the previous layer of the object, already printed, solidifies and adheres firmly on it is specific to each material of impression. Some examples are the fusion of polymeric material in the form of a filament or contained in a print cartridge melts in the hot nozzle itself and solidifies and adheres to the layer of material already printed upon cooling. Other cases such as thermosetting resins require a curing reaction for which they are exposed, once deposited on the layer of material already printed, to a source of electromagnetic radiation, in other cases a powder is deposited that is sintered by exposure to lightning. To be.
    [0014]
    [0015] In the case of the production by 3D printing of an edible product, in addition to the treatment required for the formation of a three-dimensional edible object sufficiently solid to maintain its shape during printing, a simultaneous cooking to the printing is necessary or subsequent to the object once Edible has already formed.
    [0016]
    [0017] In WO2014190217A1 a machine and a printing process of three-dimensional edible products are described. Once a desired food mixture has been created, the final food mixture can be heated or cooked using an integral oven or other appropriate heating mechanism. Allows automatic adjustment of recipes.
    [0018]
    [0019] A method for 3D printing of edible products is described in US20170164650A1. It is a method for the production of edible objects that uses the powder bed printing technique. It is based on an edible powder composition and at least one edible liquid, and said composition is subjected to powder bed printing by depositing the edible liquid on the powder in the form of layers and thus obtaining the 3D edible object with desired and adjustable microstructures.
    [0020]
    [0021] In US9723866B2 a system for manufacturing solid and free-form edible foods, controlled by software, is described.
    [0022]
    [0023] In US20170245682A1 a heating and cooking apparatus is described within the cooking chamber of a 3D food printer. It includes a cooking appliance by laser controlled by a processor that implements specific instructions of the specific computer program for the operation of the cooking and heating apparatus. The laser cooking apparatus includes at least one laser system with at least one laser beam capable of heating the food product to its cooking temperature. This device may also include an electromagnetic radiation heating apparatus that is controlled by the processor and emits electromagnetic radiation to heat the food product inside the cooking chamber at a temperature below its cooking temperature.
    [0024]
    [0025] The present invention adapts 3D printing to the production of cooked dishes from printing cartridges each containing a food product preserved under conditions that allow storage at room temperature or frozen. The layer-by-layer formation of the plate, from several print cartridges, allows the different ingredients to be combined to form the plate according to a recipe, cooking it at the time of printing so that once the printing of the object is finished it can be consumed immediately. To achieve this, technological advances are required that go beyond the state of the art and are the subject of this invention. These advances include the incorporation into the printing machine of heating systems that can be applied at each moment of printing to cook the food at the time required by the recipe and a control system of all the mobile elements of the machine adapted to the circular form of the plates and that allows to print simultaneously a sufficient number of plates occupying a limited space.

    [0161]
    [0162] A final aspect of this invention relates to the use of the three-dimensional printing machine for the production of edible products.
    [0163]
    [0164] DETAILED DESCRIPTION OF THE INVENTION
    [0165] The present invention relates to a 3D printing machine that produces a three-dimensional edible object layer by layer with an additive manufacturing method. The machine is specially designed for three-dimensional printing and simultaneous cooking of food products through complex elaborations, which include various ingredients and particular three-dimensional shapes.
    [0166] This section describes a printing machine according to a particular embodiment, mentioning in some fragment alternatives to some of the characteristics of the machine.
    [0167] According to a particular embodiment, it is a three-dimensional printing machine for cooked food (Figure 1) that is based on the vertical movement of at least three moving bodies: a printing block containing the cartridges and their guidance system (1.6 ), a printing base on which the plate (1.2) is printed and an oven (1.8) that can be positioned around the printing base or away from it depending on the needs of the recipe, capable of sliding independently on a system of bars or spindles that are anchored to a lower and an upper base forming a fixed body (1.1) and that allow to construct an edible object with a three-dimensional shape (the plate (1.2)) previously defined in a data file, starting from of one or several ingredients each contained in a cartridge (1.3) containing a nozzle (1.4) through which the ingredient is released in the form of a filament (1.5) that is deposited on the edible object under construction at the same time that it is cooked with four independent heating elements according to a series of instructions contained in the data file following a particular recipe.
    [0168] The fact that the three moving bodies can slide vertically along the bars of the fixed body allows stacking several printing modules (Figure 1a) that will move independently governed by a computer to place them at different heights thus allowing the Simultaneous printing of several dishes. Once the printing of a plate is finished, the corresponding printing set will move to the convenient height for an operator to take out the printed plate, remove the used cartridges and load the new ones for a new print. In this way the modular machine of the present invention occupies the floor surface that would be required for a machine capable of printing a single plate. On the other hand, this configuration allows heating of the plate assembly by introducing the printing base in the oven at the times that are required by moving either the oven or the printing base. Thus, it is possible to cook a printed piece at high temperature and subsequently add a cold ingredient (all this occurs within the machine of the invention, since the dish leaves the machine fully cooked and ready to consume). Also in this way oven and print base can be distanced from the print head while cooking a partially printed plate, so as not to alter the ingredients that may remain in the cartridges.
    [0169]
    [0170] One of the essential characteristics of this machine is that it incorporates four heating modes that allow cooking the ingredients while the dish is printing.
    [0171]
    [0172] It contains an orientation system (called the orientation disk of the filament heating element) of the heating element that cooks the filament of an ingredient immediately after being deposited on the plate.
    [0173]
    [0174] Another essential feature of the machine is to control the position of the printing nozzle (4.2) in a polar coordinate system by a combination of a rotation and a displacement. The polar coordinate system allows you to effectively adapt the movement of the head to the common circular shape in cooking recipes.
    [0175] The configuration of the guiding of the printing nozzle (4.2) by means of a mobile ring incorporates a diametral axis along which the head moves.
    [0176]
    [0177] Next, various sections of the machine according to a particular embodiment are described in the sections called A, B and C:
    [0178]
    [0179] A.- The printing block (Figures 2, 3 and 4) comprises:
    [0180] - a circular or polygonal support plate (2.1), capable of sliding vertically along vertical bars or spindles fixed to the machine housing, (2.2)
    [0181] - a movable ring (2.3), capable of rotating with respect to its geometric axis by means of a linear guidance system (2.4) fixed to the support plate and comprising a sliding guide arranged diametrically, which we call R axis (2.5), consisting in one or several bars or spindles supported on the movable ring by means of supports (2.6),
    [0182] - a printhead (2.7), with the ability to move along the R axis (2.5) so that the printhead moves in a polar coordinate system, by means of the combined rotational movement of the moving ring and displacement in the R axis. The print head allows to accommodate at least one print cartridge (3.1) that contains an ingredient and incorporates a plunger (3.2), capable of increasing the pressure inside the cartridge so that the ingredient is extruded through of a printing nozzle (3.3) incorporated in the print cartridge (3.1) forming the filament (3.4) that is deposited on the plate being printed.
    [0183] - at least one first heating element, called cartridge heater (3.5) fixed on the print head, to heat a cartridge.
    [0184]
    [0185] - at least a second heating element, called nozzle heater (3.6), for uniformly heating a printing nozzle, arranged at the end of the cartridge fixing means located in the print head,
    [0186]
    [0187] - at least a third heating element called filament heater (4.1), orientable, so that said heating element is arranged at all times behind the printing nozzle (Figure 4a) and in the direction of the advance of the print head. To orient the heating element of the filament it is located of fixed way on an orientation ring (4.3) of the heater, with the ability to surround a printing nozzle, without making contact with it thanks to its own design that allows the incorporation of heating elements in parts with 360 ° rotation capacity,
    [0188]
    [0189] B. - The printing base (5.1, Figure 5) is fixed on a support (5.2), which can slide on at least one displacement device, for example, one formed by one of the vertical bars or spindles (5.3), allowing the vertical displacement of said printing base.
    [0190]
    [0191] C. - The oven (6.1, Figure 6) is in the form of a cylindrical or prismatic housing, with heating elements arranged on its wall (6.2), said oven is capable of sliding on vertical bars or spindles (6.3) - example of a sliding block - so that it allows the printing base to be housed inside it at the time required by cooking the plate (see Figure 6b).
    [0192]
    [0193] The orientation disk of the filament heater can also have an element capable of depositing a layer of an ingredient, for example, a liquid, on the face of the filament that is on the outside of the plate (for example, an oil or other type of fatty matter, a derivative or analog of the egg or one of its components, a sugar or its derivatives or analogues, honey).
    [0194]
    [0195] The pressure exerted on the ingredient contained by the print cartridge and which drives it out through the printing nozzle is controlled by a computer using the sliding of a plunger (3.2).
    [0196] The movements are executed by stepper motors located either in the mobile elements themselves, joined to the moving elements by means of rigid axes or spindles, and moving with them, or at fixed points of the housing.
    [0197] The temperature of the print cartridge, the temperature of the printing nozzle, the temperature of the filament heater and the oven temperature are controlled by a computer during the printing process, using the temperature sensors and activating the necessary heating elements . In addition the cabin (that is, the inside of the machine) has fans (7.10, Figure 7b)) located in the upper base (7.7) of the fixed body behind the vents (7.9) that release the hot air from the interior at the times that are required to lower the interior temperature of the cabin, these fans are also operated by the computer.
    [0198]
    [0199] The process of obtaining a food cooked by 3D printing comprises printing said food layer by layer in polar coordinates and is based on a series of steps:
    [0200] - introduce enough cartridges for a cooked food into the housing for print cartridges, each containing an ingredient,
    [0201] - arrange a flat tray on the printing base
    [0202] - slide the printing base vertically to the proper position for dispensing the food ingredients, in the form of a printing filament, - start a computer program that reading a data file places the print body at the appropriate height for printing Once the assembly is positioned, the printing base is placed at the necessary distance from the support plate, adjusts the temperatures necessary for the start of printing on each of the heated elements, moves the print head on the R axis and / or rotate the movable ring so that it places the print nozzle of a cartridge at the starting point of printing and from there adjusts the filament exit speed and the movement of the nozzle to draw a layer with that ingredient. At each point the filament output speed and the orientation of the filament heating element is controlled so that it falls exactly on the deposited filament. Then repeat the operation with each of the ingredients that make up the recipe and once the printing of the first layer is finished, move the print base vertically to separate it from the print nozzle (4.2) the amount stipulated in the data file and Repeat the process with the next layer, repeating the printing process in as many layers as necessary to finish the plate. The temperature of each element is controlled by the computer in each layer that is printed.
    [0203]
    [0204] - Once the printing and cooking process is finished, the printing body and each of the three moving bodies will be positioned in a certain way to allow the extraction of cartridges and the plate built on the printing base. The dish is removed from the machine ready to be consumed.
    [0205]
    [0206] According to the 3D printing and cooking process of the invention, an edible product (dish) cooked from several ingredients collected each in a separate cartridge is obtained, and can be dispensed by means of a plunger that acts as an extruder integrated in the cartridge itself, with a particular design adapted to each ingredient, thermostated both in the extrusion nozzle and in the body of the cartridge and with independent temperature control for one and the other and which is the object of this invention. The machine controller allows to create a three-dimensional object (the plate), on a cylindrical, or polygonal, printing tray with additive manufacturing technique, using in each of the layers one or more ingredients according to the recipe. The thread that is generated when the ingredient is extruded from its cartridge (the filament) acquires the rheological properties necessary for printing by using certain food additives and controlling the temperature inside the cartridge and that of the extrusion nozzle. The cooking of the food starts immediately after being deposited on the edible object that is being printed. Again the action of certain food additives and cooking itself gives it the consistency necessary to print the plate and adheres it on the previously deposited layer. The additives, if necessary and for each ingredient, are included in the print cartridges, so that for example, an additive such as a thickener that must have a cream so that when it comes out of the nozzle of the cartridge solidify, it is included in the print cartridge containing said cream. For this, the machine has a filament heater orientation disc, object of this invention, which allows the filament heating element to be oriented, to be placed at all times behind the printing nozzle (4.2) and in the direction of advance of the print head The controller determines at each moment both the angular position of the filament heating element and the parameters that determine the heat received by the filament (temperature of a hot tip, flow and temperature of the air, oil or water driven, intensity or pulses of radiation electromagnetic), to adapt them to the speed of movement of the head and the needs of the recipe.
    [0207] The three moving bodies (printing block, printing base and oven) have vertical displacement capacity so that, as required, once the printing of the plate is finished or at any intermediate time the printing base on which it has been deposited can be surrounded by a contour in the form of a cylinder or prism that contains in its inner surface heating resistors (the oven). The oven can slide vertically to surround the printing plate, commanded by the controller, and heat the plate either to produce an external browning, to finish cooking, or simply to heat the plate assembly.
    [0208] In the realization of the dish, the combination of the four cooking modes implemented is essential: heating of the cartridge, heating of the nozzle, heating of the filament and final baking allows obtaining the final result.
    [0209] This three-dimensional printing machine for cooked food is used for the production of edible products.

    [0235] EXAMPLES
    [0236] Next, the invention will be illustrated by some examples of embodiment.
    [0237]
    [0238] Composition of the fixed body and the moving bodies in a 3D printing machine of cooked food.
    [0239] Figure 7 shows an exemplary embodiment of the fixed body and the moving bodies in a machine with a single printing set. It is formed by a configuration of 3 groups of vertical bars (7.1), spindles (7.2), according to specific arrangement (in the figure they are represented, by way of example, by two bars and a spindle arranged between them), to drive the movement of the elements that must slide on the z axis: the support plate (7.3), the printing base (7.4) and the oven (7.5). The bars are fixed at its lower end to the lower base (7.6) of the structure, and at its upper end to the machine head, or upper base (7.7). Both spindles and bars will be fixed at the base and head of the structure. The displacement is made by stepper motors located on the mobile body itself, by means of gears that rotate on the spindle.
    [0240] The support plate slides on the three sets of two bars by means of bearings or linear guides and its vertical movement is driven by three stepper motors meshed each of them on a spindle.
    [0241] The printing base slides on one of the two bar assemblies and a spindle by means of a support that makes it cantilever, as shown in Figure 5, its vertical movement is driven by a single stepper motor engaged on this spindle
    [0242] The oven slides on a set of two bars and a spindle different from that used in the printing base, being cantilevered and sliding by means of a motor located on the oven itself and engaged with its spindle. An opening in the side wall of the oven allows sliding vertically to completely surround the printing base as shown in Figure 6.
    [0243]
    [0244] Realization of modular machine with several printing sets
    [0245] The fact that the motors are fixed in each of the moving elements allows the vertical sliding of the moving bodies of different printing sets to use the same spindles and the machine can be constructed with three fixed spindles containing only any number of printing sets, such as It is shown schematically in Figure 1. The vertical movement of each mobile element is independently controlled by the computer.
    [0246]
    [0247] Other embodiments that allow vertical scrolling
    [0248] The sliding by means of axial bearings along the vertical bars can be replaced by any other sliding system with linear guidance, consisting of fixed vertical guides with any transverse profile and wheels or bearings that slide on them (Figure 8).
    [0249] The vertical spindles can be replaced by belts or serrated guides fixed vertically in the structure of the fixed body. The sliding is carried out in this case by means of gears located in the mobile body (Figure 8).
    [0250]
    [0251] Arrangement of the movable ring on the lift plate
    [0252] The head can move on the R axis located diametrically in the moving ring, which is rotated by a linear guidance system (2.4; 9.1). Plate The lift has an inner cut in a circular shape and its outer shape can be circular or prismatic, adapting to the arrangement of the vertical bars (Figure 2). The movable ring rests on the support plate by any system that allows the movable ring to rotate with respect to the lift plate, keeping the geometric axes of the inner circle (Figure 9) of the lift plate and the one of the bearing plate invariable and coincident at all times. mobile ring Both the displacement of the print head on the R axis and the rotation of the moving ring with respect to its geometric center are controlled by stepper motors governed by the computer.
    [0253] The movable ring can have any cross section that allows the support points to be installed on the support plate and a drive system. In a particular application and without loss of generality, the movable ring is anchored by three or more bearings (linear guidance system 2.4; 9.1), which can rotate freely on its axes that are fixed on the support plate. The edge of the outer or inner contour of the movable ring slides over the linear guidance system (2.4), which in a particular embodiment are the bearings. These three or more fixed points of the contour of the moving ring determine and make the position of its axis invariable in any displacement of the printing nozzles. Also in a specific application and without loss of generality, the contour of the movable ring is fitted with a toothed belt (9.2) that meshes with a pinion (9.3) whose axis is fixed to the support plate. The gear formed by the pinion and the belt transmits the movement to the moving ring from a stepper motor placed on the lift plate.
    [0254]
    [0255] R axis layout
    [0256] The head can move along at least one axis that is arranged diametrically in the movable ring and supported on it at its two ends by means of two supports (2.6). The displacement of the head on the shaft is driven by any means capable of transmitting the rotation of the motor shaft of a stepper motor to the sliding of the head. In two specific applications and without loss of generality, this type of mechanical transmission can be carried out by means of a spindle or by a transmission belt. The motor (2.8) will be located on the moving ring (2.3).
    [0257]
    [0258] Print head
    [0259] In the printing of the layer-by-layer object it is necessary that some kind of physical or chemical transformation takes place in the printing material from the time it passes through the nozzle until it adheres firmly to the lower layer of the object and becomes mechanical consistency. For example, in the case of molten plastic printing, this transformation simply comes from the temperature change since the polymer passes through the nozzle, at high temperature, melting and acquiring a fluid consistency to cool down by touching the already printed surface of the object, solidifying again. In other cases, however, adhesion to the previous layer of the object requires that a chemical reaction occur which can be accelerated by an increase in the temperature of the material once it has already been deposited on the lower layer of the object.
    [0260]
    [0261] In other cases it may be the dehydration of the printing material once the nozzle leaves the one that makes it acquire consistency and this requires an application of a heat source directly on the printed material cord. This type of action acquires special relevance in the printing and simultaneous cooking of edible products.
    [0262]
    [0263] Each ingredient is contained in a print cartridge. At some point in its base is the extrusion nozzle, a conduit with cross-section and length and geometry appropriate to the rheological properties of each ingredient and the three-dimensional shape of the dish that allows the ingredient to be pushed out by the pressure generated inside the print cartridge by a drive controlled by the computer. In a particular embodiment (Figure 10), the print cartridge has a circular cross-section, is closed at the top by a plunger that acts as an extruder (10.1) sliding inside and pushing the ingredient through the nozzle (10.2) located at the bottom. The piston shaft is attached to a spindle (10.3) that moves forward or backward when turning because it is threaded into a fixed nut (10.4). The print nozzle will be integrated in the cartridge. In a particular embodiment the cartridges are constructed of a material suitable for food preservation and are disposable. The piston is also integrated in the cartridge, has a metal element integral with it on the outside (10.5) and is attached to the spindle by means of a magnet located at the end of that spindle.
    [0264] In a particular embodiment (Figures 9 and 11), to prevent the weight of all head motors from falling on the movable ring, the sliding plate (9.4) is constructed on the vertical bars or guides, and at all times parallel to the plate of support and solidly attached to it containing another ring (9.5) (solidly attached to the mobile ring) and a displacement device that we call a linear guide (9.6; 11.1) (which at all times will be parallel to the R axis and placed on it) which can consist of two bars on which a support plate (11.2) of the motors that houses both the motors (11.3) that govern the pistons, as well as those of guiding the orientation ring of the filament heating element (11.4) slide freely. The movement of this motor support plate is dragged at all times by the print head, without new transmission elements that require computer control.
    [0265]
    [0266] In a particular embodiment, the print head of the machine object of this patent incorporates three of the four heating elements used to cook the food while printing: The cartridge is surrounded by the heating element (3.5) of the cartridge, fixed in the head and its surface houses a temperature probe (3.7). The nozzle is surrounded by the heating element (3.6) of the nozzle and houses at some point on its surface a second temperature probe (3.8). In this particular embodiment the filament heater (4.1 in Figure 4) is located on the orientation ring (4.3) of the filament heater, which surrounds the printing nozzle (4.2) without touching it. The filament heating element may consist of a hot tip, which may be a metal rod ending in a sharp, flat or blunt tip, heated by an electric resistance, or a source of any electromagnetic radiation, a hot air stream or a hot oil jet. This heating element is fixed in the orientation ring. The orientation ring can be rotated, driven by a stepper motor controlled by the machine control software so that the filament heating element is always positioned on the cord of printing material that has just been deposited. The double bearing system (10.6 and 10.7) shown in Figure 10 allows the orientation ring of the filament heater to rotate while both the head body and the print cartridge are fixed. So that the orientation ring of the filament heater can rotate 360 °, a wireless electric charge module is provided with a fixed coil located in the head block (10.8) and a coil mobile located in the orientation ring (10.9) of the filament heater. The fixed coil will be anchored at the bottom of the support plate (11.2) of the motors. Any fluid that uses the filament heating element would be stored inside the hollow bars (10.10) that support the filament heating element. For precise control of the orientation of the filament heating element, the plate data file collects the angle of rotation (referred to a reference orientation set in the printing nozzle) determined by the last two points where it has been located the printing nozzle (scheme in Figure 4). Figure 12 shows a diagram of the importance of the orientation of the filament heating element (12.2). If the position of the filament heater is fixed with respect to the nozzle (12.1), as shown in Figure 12a, at different times (t = 1, t = 2, t = 3, t = 4) the heater of the filament would not be placed at all times on the newly deposited filament and the heat transfer would be imperfect, a second pass of the head on the already printed filament would be necessary placing the heater exactly on the filament as seen in Figure 12b (moments of time t = 5, t = 6, t = 7, t = 8). In the device of this invention (Figure 12c) the orientation capacity of the filament heater means that in a single pass both the nozzle (12.3) and the filament heater (12.4) are placed simultaneously on the newly printed filament, so that The ingredient from which the filament is formed is deposited on the plate and cooked simultaneously.
    [0267]
    [0268] The printhead is designed to hold up to 6 print cartridges. The different print cartridges are arranged radially in the print head (Figure 3). This arrangement allows you to take full advantage of the print field. When the print head is fully displaced on the R axis, the printing nozzles are arranged on a circumference whose center coincides with the axis of the moving ring. In this way, by rotating the ring, any nozzle can reach any point in a circular area, centered in the center of the moving ring. The dead space, space that the print nozzle cannot access is reduced to a circular crown of width equal to that of the radius of a circle that enveloped the print cartridge, the printable area is represented in gray in Figure 3. This effect is especially interesting in the printing of objects whose base approximates a circular shape or is composed of curved shapes with a circular envelope, but the operation also adapts to the figures formed by straight lines or with rectangular contours. The fact that the rotation that allows the coordinate to be varied is carried out by means of the movement of the moving ring leaves the entire interior surface diaphanous, available for the movement of the printing nozzles (Figure 3).
    [0269]
    [0270] Print tray
    [0271] Printing is done on a flat sheet or tray (5.4), which is fixed on the printing base (5.1) by any system that fixes its position, keeps it horizontal and prevents its displacement during printing. As an example and without loss of generality the tray has a protrusion in its lower part, with any shape. Figure 5 shows the tray with a protrusion at its bottom, as an example of a triangular shape (5.5) that fits into a slot (5.6) made in the printing base, in another application the tray is fixed by magnets (5.8) located on the printing base, while the base of the tray is made of a metal element or has metal plates (5.8) attached to the magnets. Tray (5.4) must be flat to allow layer-to-layer printing. The plate can be served directly on the tray or, for aesthetic reasons, introduce the tray with the plate printed on a support with particular shapes to serve it on the table. In this case the tray would fit on the base of that support exactly the same as it does on the print base.
    [0272]
    [0273] Data file
    [0274] The data file of the plate to be printed will allow the computer to control the entire printing process, including the movement of all the moving bodies, the heat treatment to which each ingredient is subjected both within the print cartridge, as in the printing nozzle and after being deposited on the plate, collecting the temperature values measured by the temperature control probes and activating the corresponding heating elements. It also collects data on the ingredient's drive through the printing nozzle.
    [0275] The information on the three-dimensional shape of the plate is contained in the data file that describes layer by layer the shape of the edible object in polar coordinates, that is, each point of the object is defined by three coordinates: height, z, with respect to a plane 0 that fixes the machine as the origin of this coordinate, the angle of rotation, of the moving ring, with respect to an origin set by the machine and the distance, r, between the nozzle and the geometric center of the moving ring (Figure 3). The points that form a layer of the edible object to be printed are listed in the order in which they must be reached by the printing nozzle during printing and the data file also contains the speed of head movement between each point and the next, the Extrusion rate of the ingredient, the temperatures required in each temperature control probe and, where appropriate, the electrical energy, air flow, water or oil required in each heating element. The data file also includes at each point, the angle a (Figure 4), formed between the line (4.3) (it is the imaginary line that the computer program takes as origin "0" of the alpha angle) that joins that point with the previous one in the printing order (4.3) and a fixed reference line (4.4) in the print head, thereby determining the orientation of the last section of the printed filament. This data will allow the filament heating element to be oriented, just above the filament once deposited.
