Definitions
- the invention relates to an additive manufacturing (AM) process and an apparatus for carrying out the process.
- AM additive manufacturing
- the invention relates to an additive manufacturing (AM) / SD printing process.
- Additive Manufacturing is a manufacturing process that builds SD objects based on data from a CAD source layer by layer.
- the invention is therefore based on the object to present an additive manufacturing method and apparatus for performing the method, which also allow an untrained user to apply the method and this with a simple investment.
- powder layers are applied to a support surface and then powder is removed from the layer again in regions and the layer is thus contoured. Then the layer is fixed.
- the AM process of the present invention thus functions similarly to other powder-based AM technologies in which the starting material is used in powder form and applied sequentially on a mobile platform in a powder bed. Subsequently, during the building process of each layer, the unwanted area or a plurality of undesired areas of the powder bed are removed with a movable object based on the CAD data.
- Confirmation copy End of the removal process of each layer remains corresponds to the desired contour of the layer, which is then sintered or melted using a heating element and fixed by solidification or by a chemical reaction.
- the support surface can be moved to remove unwanted powder or unwanted areas of the powder bed.
- the sintering phase or melt can be achieved with various heating methods such as electric heating elements, infrared, microwave, etc.
- the platform can be returned to the starting position in order to be able to extract from the powder the objects integrated therein.
- a preferred embodiment provides that the powder is removed with a magnet.
- a magnetic scanner unit is used to remove the unwanted contour areas of the material from the powder layer and to separate them in a container or at a remote location before the layer is fixed.
- the magnetic scanner unit is based on the physical operating principle of magnetic force to remove the material, possibly in combination with the use of magnetic brushes.
- the removed material can also be removed from the magnetic unit of the scanner by means of a second, more powerful magnetic head to separate it.
- an electromagnet with electromagnetic pulses is advantageous
- the magnet it is proposed to remove the powder with a vacuum pump.
- the powder can be removed with a slider or a brush.
- a special embodiment provides that the powder is removed by evaporation.
- the fixation can be done in different ways. It is advantageous if the fixing takes place by means of a heat input, which melts or activates at least partial regions of the outer surface of the powder particles.
- the particles can also have a surface which can be activated by heat, radiation or chemical substances, which permits a time-controlled fixation.
- the powder used may be a metal, a polymer or a ceramic powder. Particularly preferred is a fabric that is removable with a magnet.
- the heating element enables simultaneous sintering or melting of the entire layer, the construction time is significantly reduced compared to selective additive processes such as Selective Laser Melting (SLM) or Fused Deposition Modeling (FDM).
- SLM Selective Laser Melting
- FDM Fused Deposition Modeling
- the heater may also gradually heat the entire surface of the powder bed. Even if the heater is moved slowly over the powder bed, for example, in order to gradually expose the entire powder bed to the same heat input, the method is far faster than if all contours of the object, for example with a laser, are treated in a controlled manner.
- the fixing devices of the device according to the invention are a surface radiator.
- the intensity of the homogeneously radiating cross-sectional area of the heat source is large enough to reflow the powder without requiring extremely high power densities, thereby avoiding the need for using laser or other costly heat sources.
- FIG. 1 shows a base plate in which a building platform is embedded, which is in Z-
- FIG. 2 shows the construction platform from FIG. 1 with a powder layer on its surface, in which powder has been removed in partial areas
- FIG. 3 shows the build platform shown in FIG. 2 after the powder has been fixed in a central area.
- FIG. 1 shows a base plate 1 into which, for example, a rectangular building platform 2 is embedded and which is covered with powder 3.
- a magnet 5 (or another tool suitable for removing the respectively used powder) is fastened to an arm 4 and this arm 4 can be driven in a controlled manner over the powder layer 3 so that powder is removed from the building platform 2 from specific areas.
- a metallic powder is used, which is removable with the magnet 5.
- the block 2 can be moved by a movement of the base 1 relative to the arm 4 in order to remove powder in specific areas.
- FIG. 2 shows this block after removal of powder in the regions 5, 6, 7 and 8. This results in particular in a clearly delimited central region 9, which can subsequently be fixed.
- the powder has also been removed on the surfaces 10 to 17, so that only a central central square surface 12 remains after the fixation.
- This technology can be used on Earth and especially on the Moon or Mars.
- lunar or Martian regolith have magnetic properties
- a body mission can be made on a space mission by means of a magnetic scanner from the material present on the moon or Mars.
- the absence of oxygen in the atmosphere of the moon or Mars simplifies the process since no protective glass is needed.
- solar heaters can be used to provide the necessary energy to build up the bodies.
