Definitions
- a process for the additive manufacturing of components is specified.
- generative manufacturing processes also known as additive manufacturing or 3D printing processes - are known in the state of the art. These are computer-controlled processes in which components are manufactured from liquid or solid materials according to specified masses and shapes using chemical and/or physical processes, in particular using melting and/or curing processes. Generative manufacturing processes are suitable, among other things, for the economical production of prototypes, unique pieces or components with complex geometry.
- melt-based printing processes currently known in the art, e.g. B. “Fused Deposition Modeling” (FDM), “Fused Filament Fabrication” (FFF) or “Fused Granular Fabrication” (FGF), an individual print head (nozzle) is used to print components.
- FDM Fusion Deposition Modeling
- FFF Filament Fabrication
- FGF Femented Granular Fabrication
- an individual print head (nozzle) is used to print components.
- print heads running in parallel are also used, for example in portal systems (e.g. desktop printers).
- the publication DE 10 2019 124 311 A1 shows a nozzle arrangement for an extruder head that is used in an additive manufacturing system.
- the extruder head has an arrangement of several nozzles in a front panel.
- the nozzles are integrated in a common head, which can be used for the component-forming process by rotating around the axis and switching on the respective nozzles. This enables more efficient printing or the printing of different materials.
- a printing device for the additive manufacturing of components has an extruder device, a distributor device connected to the extruder device, and a plurality of nozzles spaced apart from one another.
- the extruder device is preferably a central extruder for melting the material to be printed.
- the extruder device which is preferably located statically in the production environment, thus serves as a central material or melt supply.
- the distribution device is preferably a distribution system for guiding the melt or for guiding the extrusion material.
- the distribution system can be a hot runner system made from injection molding tools.
- the melt or the extrusion material can be conveyed to the nozzles directly connected to the distributor device via the distribution device or the distribution system.
- the nozzles can, for example, be spaced apart from one another at a uniform distance, ie all nozzles directly adjacent to one another can each have the same distance.
- the distance between two adjacent nozzles is preferably larger than a lateral extent of the components to be manufactured or manufactured or larger than the individual component dimensions of the components in the x-direction and / or y-direction (the z-direction, which is perpendicular to the x -direction and y-direction, here refers to the direction in which the components are built up during printing or in which one Component platform on which the components are printed in the process can be moved or lowered).
- a large number of components are manufactured by means of the printing device, with extrusion material being fed from the extruder device via the distributor device to the nozzles, and with the components being manufactured at the same time or simultaneously.
- a separate component is preferably produced using each of the nozzles.
- the components to be manufactured or manufactured by the method can in particular be identical.
- the components are manufactured in the method in such a way that the construction or printing of identical component sections takes place simultaneously with respect to all components.
- the production of the components or an additive manufacturing process is preferably a melt-based printing process.
- the manufacturing process can be a so-called fused deposition modeling process (FDM), a fused filament fabrication process (FFF) or a fused granular fabrication process (FGF).
- FDM fused deposition modeling process
- FFF fused filament fabrication process
- FGF fused granular fabrication process
- the printing device has a movable construction platform or component platform onto which extrusion material emitted from the nozzles is printed in the method described here or during the manufacture of the components.
- the printing device can have an actuator for moving the component platform, in particular for moving the component platform in the z direction.
- the actuator can be, for example, a manipulator or robot.
- the nozzles of the printing device can preferably be arranged with respect to the component platform in such a way that they are each at the same distance from the component platform. This is possible in a particularly simple way, simultaneously using the method described here or to print or manufacture a plurality of components at the same time, the components manufactured by the method preferably each being identical.
- the construction time when producing 3D components is a very time-consuming and therefore important factor in the production costs of printed components.
- the method described here advantageously enables a significant reduction in construction times and thus a significant reduction in manufacturing and/or investment costs.
- Figure 1 shows a schematic representation of a method described here for the additive manufacturing of components 2.
- a printing device 1 for the additive manufacturing of components 2 is provided.
- the printing device 1 has a central extruder device 3 for melting the material to be printed and a distributor device 4 connected to the extruder device 3.
- the distribution device 4 can be designed, for example, as a melt distribution channel and can, for example, be a hot runner system made from injection molding tools.
- the printing device 1 has a plurality of nozzles 5 spaced apart from one another, which are connected to one another via the distributor device 4.
- the printing device 1 has a component platform 6 that can be moved by an actuator or robot (not shown).
- a large number of components 2 are manufactured simultaneously by means of the printing device 1, with extrusion material being fed from the extruder device 3 via the distributor device 4 to the individual nozzles 5 and the extrusion material being printed onto the plane component platform 6 by means of the nozzles 5.
- the flat construction platform 6 can be moved below the exit of the nozzles 5, on which the printed parts or components 2 are built.
- the components 2 can thus be printed or manufactured simultaneously by means of the plurality of nozzles 5, to which extrusion material is supplied via the common extruder device 3 and the distributor device 4.
- a separate component 2 can be manufactured using the method using each of the nozzles 5.
- the individual components manufactured by the method are preferably identical in each case after the printing process has been completed.
- the printing process can in particular be a melt-based printing process.
- the construction time can be significantly reduced, particularly with melt-based printing processes, and in particular when using extruder technology (e.g. direct printing from granules, pellet printing) in the production of two or more components 2.
- extruder technology e.g. direct printing from granules, pellet printing
- the construction time can be halved or the investment in an additional system (depending on the number of units) can be prevented.
- the exemplary embodiment shown in the figure can have further features according to the embodiments of the general description.
