    [0202] FIG. 1 shows a printer cartridge 100 according to the invention. The printer cartridge 100 comprises an outer wall 101 of plastic that at least partially encloses an inner space 102. In the inner space 102 is a chocolate mass 103. The printer cartridge 100 is a 3D printer cartridge that is configured for use in a 3D printer 200. For this purpose, a mould of the outer wall 101 is configured as a positive mould with respect to a negative mould formed by a receiving shaft of the 3D printer 200. The printer cartridge 100 comprises a nozzle 104 with a circular outlet opening 105. The outlet opening 105 has an opening area of 1 mm.sup.2. The printer cartridge 100 further comprises a piston 106 with a plunger 107. When force is exerted on the piston 106, the plunger 107 can reduce a volume of the inner space 102 such that the chocolate mass 103 is pressed through the outlet opening 105 of the printer cartridge 100. The chocolate mass 103 can thus be dispensed from the printer cartridge 100 in strand form. Accordingly, the printer cartridge 100 is configured according to the principle of a syringe. The chocolate mass 103 comprises a total fat content of 42 wt %, based on the total weight of the chocolate mass 103 of 25 g. The total fat content comprises a plurality of fatty acid residues, each without a double bond, and comprising a number of C atoms per fatty acid residue in the range of 12 to 24, to a total content of 54 wt %, to based on the total fat content. Furthermore, the total fat content comprises a plurality of fatty acid residues, each without a double bond, and comprising a number of C atoms per fatty acid residue in the range of 16 to 24, to a total content of 49 wt %, based on the total fat content. The total fat content further comprises a plurality of fatty acid residues, each without a double bond, and comprising a number of C atoms per fatty acid residue in the range of 16 to 20, to a total content of 48 wt %, based on the total fat content. In addition, the total fat content comprises a plurality of fatty acid residues, each without a double bond, and comprising a number of C atoms per fatty acid residue in the range of 16 to 18, to a total content of 48 wt %, based on the total fat content. The total fat content comprises a plurality of fatty acid residues with a number of C atoms per fatty acid residue in the range of 4 to 10 to a total content of 2 wt %, based on the total fat content.

    [0203] FIG. 2 shows a device 200 according to the invention 200 that is a 3D printer. The 3D printer 200 comprises the printer cartridge 100 according to FIG. 1. The printer cartridge 100 is received in a receiving shaft of the 3D printer 200 in such a way that that the nozzle 104 with the outlet opening 105 is arranged over a substrate 202. The nozzle 104 can be guided by means of a rail system 207, a vertical translation of the substrate 202 by a lifting device 203 (shown by arrows respectively) and motors 206 in such a way that the outlet opening 105 can be moved over the substrate 202 at each point of a three-dimensional working volume. In this manner, chocolate products 400 can be produced with the device 200 in a plurality of moulds, each of which fits into the working volume. Guiding of the nozzle 104 by means of the rail system 207 and dispensing of the chocolate mass 103 from the outlet opening 105 are carried out in a computer-controlled manner by a data processing device 205. The data processing device 205 is conductively connected to a power supply (not shown) and connected in a signal-transmitting manner to the motors 206 and a linear motor 208. In this manner, the data processing device 205 can drive the motors 206 and the linear motor 208. The linear motor 208 comprises a runner 209 that can exert a force on the piston 106 of the printer cartridge 100 so that the chocolate mass 103 can be dispensed from the outlet opening 105 onto the substrate 202. In order to allow the chocolate mass 103 to be set to a moulding temperature for this purpose, the device 200 further comprises a temperature setting device, which comprises a heating coil 210 that is arranged around the receiving shaft such that the chocolate mass 103 can be heated in the printer cartridge 100 received in the receiving shaft. The heating coil 210 is shown here in a sectional view. Furthermore, the data processing device 205 comprises a hard drive on which is stored a digital data set with CAD-models of the plurality of forms of the chocolate products 400. The computer-controlled movement of the outlet opening 105 takes place along a three-dimensional trajectory 204 that lies in the working volume. During the movement along the three-dimensional trajectory 204, a distance 201 between the substrate 202 and the outlet opening 105 increases monotonically. The device 200 is therefore suitable for carrying out the method 300 according to FIG. 3. Furthermore, a chocolate product 400 can be produced with the 3D printer 200 at a printing rate of 0.2 min per g of chocolate mass. The chocolate product 400 can be consumed after printing, i.e. does not need to be further processed or actively cooled. The chocolate product 400 is therefore a chocolate finished product.

    [0204] FIG. 3 shows a flow chart of a method 300 according to the invention. In a method step a) 301 of the method 300, the device 200 of FIG. 2 and the printer cartridge 100 of FIG. 1 are separately provided. In a subsequent method step b) 302, the printer cartridge 100 is inserted into the receiving shaft of the 3D printer 200. In a method step c) 303, the chocolate mass 103 is set to a moulding temperature, in this case heated, in the printer cartridge 100 by means of the temperature setting device with the heating coil 210. In a method step d) 304, the chocolate mass 103 is moulded at the moulding temperature by means of the piston 106, the plunger 107 and the nozzle 104 with the outlet opening 105 of the printer cartridge and thereby dispensed onto the substrate 202 of the device 200. In this manner, a chocolate finished product is produced on the substrate 202 as a chocolate moulded body. In the method step d) 304, the outlet opening 105 of the nozzle 104 follows a three-dimensional trajectory 204, along which the distance 201 between the substrate 202 and the outlet opening 105 increases monotonically. Furthermore, in method steps b) 302 to d) 304, the chocolate mass 103 is not heated above the moulding temperature of 29 C. Furthermore, a minimum temperature of the chocolate mass 103 in method steps b) 302 to d) 304 is not below 20 C. From method step b) 302 to d) 304, the method 300 comprises no tempering of the chocolate mass 103 within the meaning of chocolate production, i.e. no pre-crystallization of the chocolate mass 103. Rather, the chocolate mass 103 in the printer cartridge 103 is already pre-crystallized in the method step a) 301 so that it has a high beta-5 crystal content.
