- US 2018/0345573 Al describes an extrusion-based manufacturing process based on 3D printing in which a metal wire (thread) is used, in which it is fed to a liquefier, which has a
- Melt is generated, which is applied in layers to a surface of a workpiece table via an extrusion pipe.
- An inert gas pressure is used to force the melt out of the extrusion tube. There is one for ordering
- the tool table should be heatable in order to strengthen the metal and the
- Aluminum alloys. DE 10 2014 018 081 A1 provides for additive manufacturing by means of extrusion of metal composite in a 3-stage process, namely the manufacture of a green part, the debinding of the green part and the sintering of the green part. During the printing process, only the composite part is plasticized here, which takes place at a low temperature level.
- Ultrasonic transducers are used to prevent the nozzle from being attached to the walls.
- the object of the invention is to meet the conditions for extrusion-based additive manufacturing of workpieces from thixotropic (partially liquid processing) metal alloys e.g. Identify and optimize aluminum alloys.
- Engaging merged rods are pushed into the channel so that they simultaneously act as pistons for the extrusion of the semi-solid material produced serve, with a preheating device by an induction coil including a cap for field concentration, which enclose the channel, with a heater in the form of a resistance heater for

- the channel is formed in the area of the induction coil for preheating by a sleeve made of glass or ceramic. This has the advantage that the electromagnetic field can heat the rods almost unhindered.
- the nozzle channel has a ceramic non-stick coating, e.g. has a boron nitride coating to adhere
- a further embodiment of the device according to the invention provides a time control which can be set so that when globulites become larger, the for
- a waste collector is arranged on the workpiece table.
- the inventive method for extrusion-based additive manufacturing of products from a thixotropic metal alloy in which a supplied starting material is brought into a semi-solid processing state by heating, extruded through a nozzle and applied in layers to a product to be built, takes the idea of using the starting material as an extrusion piston, in which the not yet liquefied starting material has a ready-to-use structure with a globular structure, is rod-shaped, with a male and a female end, so that the rods can be joined together one after the other to form a rod by inserting the male end into the female end The end engages and the rod is used as a piston for the extrusion by inserting into this
- a feed force is introduced, with a preheating device and a heater in the form for heating a resistance heating can be used, the
- the heating surface of the resistance heating is kept so small that aging of the raw material in the form of the enlargement of the globulites is minimized.
- the feeder for the starting material is in a device for the extrusion-based production of products from a thixotropic metal alloy, with a magazine for
- the rod-shaped starting material can be connected on the input side into the channel to form a rod, in that a male end of a rod engages in a female end of the preceding rod, before that the magazine and the guide channel for the
- Fig. 1 shows a device according to the invention for extrusion-based additive manufacturing of products from a metal alloy, preferably from thixotropic aluminum alloys and in particular from the alloys A-356 / EN AC-42100 / EN 1706 (AlSi7Mg0.3 and THIXALLOY 540 (AlMg5Si2Mn) .
- the device has a feeder 2 for the
- the starting material which is arranged outside the housing 1.
- the starting material is rod-shaped 3, with a male and a female end 4, 5, so that the rods 3 can be joined together one after the other to form a rod.
- the joined rods 3 are moved through a channel 6 to a heatable nozzle channel 12 of a nozzle 11 and here in the partially liquid state on an adjustable one
- Workpiece table 15 used to build up a product in layers.
- the housing 1 which is filled with an inert gas, so that there is a risk of contamination by reactive air occurring during partial melting Gases such as B. oxygen and carbon dioxide is excluded.
- the workpiece table 15, which is also arranged in the housing 1, can be moved in the coordinates x, y and z by means of an adjusting device 16. That is because of the extensive equipment
- Equipment around the channel 6 and the connection to the feeder 2 is more advantageous than moving this equipment.
- the workpiece table 15 has a waste collector 17 which picks up aged starting material or coarsened starting material (e.g. globulites larger than 1/8 of the nozzle outlet opening).
- a waste collector 17 which picks up aged starting material or coarsened starting material (e.g. globulites larger than 1/8 of the nozzle outlet opening).
- Fig. 2 shows the equipment for processing the
- the joined rods 3, which have a ready-to-process globular structure, preferably with an average grain size ⁇ 100 mpi, are through a Propulsion generating device 20 pressed into the channel 6 so that they also serve as a piston for the extrusion of the semi-solid material to be discharged.
- Gear conveyors or screw conveyors are used as the propulsion generating device 20, which engage in corresponding recesses in the joined rods 3, comparable to a rack or a threaded rod.
- the joined rods 3 have a guide groove and the channel 6 one with the
- Processing devices a preheating device with an induction coil 8 and a cap for field concentration 7,
- the induction coil 8, the cap for field concentration 7 and the heater 10 encase the channel 6, which is formed in the area of the induction coil 8 for preheating by a sleeve 9 made of glass or ceramic.
- the heater 10 is preferably a multi-circuit resistance heater to the metal alloy in an accurate to bring and maintain a partially liquid state. The fact that the heating surface is kept small allows
- a laser or an induction coil is used to preheat the layers of material that have already been deposited.
- the aforementioned two-stage heating counteracts this, as does the ultrasonic generator 14 arranged in the area of the nozzle 11.
- the latter promotes the maintenance of the uniform distribution of the solid (globulites) and liquid
- the nozzle channel 12 has a ceramic non-stick coating (e.g. a boron nitride coating).
- the feeder 2 for the starting material comprises the magazine 18 for exchangeable rod-shaped 3
- Raw material is prepared for extrusion.
- the rod-shaped 3 starting material can be connected on the input side into the channel 6 to form a rod in which a male End 4 of a rod 3 each engages in a female end 5 of the preceding rod 3. Approved
- Release pins 21 ensure that the following rod 3 only emerges from the guide channel when the
- the rod-shaped starting material is preferably inserted horizontally into the magazine 18 and is rotated in the guide channel 19 about a perpendicular to the longitudinal axis of the rod, so that the rod-shaped starting material then slides vertically into the channel 6.
- This arrangement has the advantage over vertical magazine storage that gravity is used to advance the rods or that the magazines can easily be exchanged during operation.
- the magazine 18 and the guide channel 19 are with a
