Definitions
- the invention relates to a method having the features of the preamble of claim 1 and a device having the features of the preamble of claim 7.
- the solidification of the powder particles by means of the electron beam can take place via at least partial melting and solidification.
- the process chamber is that area of the device for the additive manufacturing of a component in which a controlled atmosphere, preferably a vacuum, can be produced and maintained.
- the additive manufacturing by the electron beam takes place within a partial area of the process chamber, which is referred to as a construction area.
- the electron beam causes an electrically negative charging of the powder particles to be solidified and the structure produced by the solidification of the powder particles.
- WO 2016/00448 A1 describes a powder of spherical powder particles having a size greater than 10 micrometers and an average BET surface area of greater than 0.08 m 2 / g. This powder is better versinterbar.
- the disadvantage here is that not all materials with a spherical particle shape can be produced inexpensively with such a high surface area.
- the object of the invention is to provide a simple and inexpensive method and a simple and inexpensive device in which at least one, preferably several or all, of the problems discussed above are avoided. This object is achieved by a method having the features of claim 1 and an apparatus having the features of claim 7. Advantageous embodiments of the invention are defined in the dependent claims. It is provided that
- the structure resulting from the solidification of the powder particles is electrically discharged after solidification by a plasma.
- the charges introduced into the material by the electron beam first penetrate into the volume of the material and then migrate to the surface.
- the plasma forms a very well electrically conductive medium surrounding the powder particles or the structure and can thus efficiently dissipate the charges that are located on the surface.
- the hitherto known irradiation of the powder particles with the strongly defocused electron beam is ideally no longer necessary. This causes a shortened process time and thus a significant cost reduction.
- the invention has at least one of the following advantages:
- the invention has the advantage that the powder particles to be solidified need not already be introduced into the apparatus for additive production in pure form, since existing impurities are removed before solidification anyway by the cleaning by means of plasma or at least reduced so far that they no Represent problem more. Certain impurities, eg. B. with oxygen can not be avoided if the powder particles come into contact with an uncontrolled atmosphere before solidification. Also, such impurities can be removed in the above sense.
- metallic powder particles are used, for.
- titanium or titanium alloys high-alloy steels, aluminum or aluminum alloys, refractory metals or refractory metal alloys, cobalt alloys or nickel-base superalloys.
- an electron beam is used in a power range of at least 2 kilowatts.
- the plasma generating device is formed separately from the beam generating device for generating the electron beam, so it is not formed by these.
- the powder particles to be solidified have a spherical initial shape.
- Spherical initial form is to be understood as the following forms:
- agglomerated or aggregated primary particles which, as an agglomerate or aggregate, have a spherical shape or a rounded shape
- the plasma generating device may be arranged - at least partially or completely - outside or inside the process chamber.
- a low-frequency or high-frequency alternating voltage can be used by the plasma generating device, or the plasma can be excited by electromagnetic radiation in the microwave range.
- a process atmosphere is provided and the plasma is prepared from the process atmosphere.
- This is one possibility for producing a low-pressure plasma.
- Such a method could, of course, also be produced on the basis of a gas different from the process atmosphere.
- the use of a low-pressure plasma has the advantage that a large area (eg the powder layer) can be applied simultaneously.
- a low-pressure plasma can act on the powder particles from all sides and thus produces an effective discharge effect.
- a low-pressure plasma can be excited from outside the process chamber.
- a plasma can be excited by:
- a low-pressure plasma which is produced by capacitive coupling (for example produced by a plate reactor), inductive coupling (for example generated by a coil) or by electromagnetic radiation (for example by a magnetron generated) is generated. It may also be provided that an atmospheric pressure plasma is used. This can be generated in a manner known per se. The generation of the plasma can be independent of any existing process atmosphere or in vacuum, z. B. also outside the process chamber.
- powder particles to be solidified are provided as a powder layer prior to solidification.
- the powder layer typically has a layer thickness of 50 to 150 microns.
- a controlled process atmosphere can be maintained in the process chamber.
- the process atmosphere can be added to a reactive gas.
- the at least one plasma-generating device has at least one electrode pair, wherein the construction area for the additive manufacturing is arranged at least partially between the electrodes of the electrode pair.
- One of the electrodes of the electrode pair may be formed by a portion of a wall of the process chamber or the construction chamber.
- One of the electrodes of the pair of electrodes is grounded, while an alternating electrical voltage can be applied to the other electrode of the pair of electrodes.
- the at least one plasma generating device has at least one induction coil (which can be acted upon by an electrical alternating voltage), the construction region being arranged at least partially within at least one winding of the at least one induction coil.
- the at least one plasma-generating device has at least one magnetron, the magnetron being arranged inside or outside the process chamber.
- a feeder device for feeding powder particles to be solidified to the construction area (eg a squeegee, preferably with steel, rubber or CFK lip), wherein it is preferably provided that the feeder device is in communication with the at least one plasma generating device and has at least one discharge opening, via which plasma can be discharged.
- a process atmosphere with a pressure p of 1 10 millibar ⁇ p ⁇ 1 millibar can be provided.
- Fig. 1 shows a device with low-pressure plasma, generated by a
- Fig. 2a, 2b a device with low-pressure plasma, generated by a
- Fig. 3a, 3b a device with an atmospheric pressure plasma
- a provision unit 13 for providing and maintaining a process atmosphere in the process chamber 2 is provided. It is a non-illustrated pressure reduction device for providing and maintaining a relation to the environment lowered pressure or a vacuum in the process chamber 2 is provided.
