  • Publication number: 20210031440
    Abstract: In a photochemical method for the additive manufacture of components a construction material is used which can undergo a further phase transition controllable by cooling between the liquid phase and a solid aggregate state as a second solid phase during the additive manufacture, which does not influence the first solid phase produced by radiation for the construction of the components. The further phase transition is controlled during the construction of the components so that component regions solidified whilst forming the first solid phase are supported by surrounding construction material in the second solid phase. A block of solidified construction material formed by the transition into the second solid phase is conveyed by an advancing device laterally approaching and engaging the block contrary to the construction direction in order to construct the components. This enables a continuous fabrication of the components without interruptions due to a change of the construction platform.

  • Patent number: 10297385
    Abstract: The invention relates to a for a targeted shaping of the magnetic field of a single permanent magnet or an arrangement of a plurality of permanent magnets, wherein magnetic material from selected locations of the single permanent magnet or at least one of said permanent magnets of the arrangement is removed by means of at least one of the following removal procedures for shaping the magnetic field: laser ablation using laser radiation, high-pressure waterblasting using high-pressure water jets and mechanical ablation using a non-magnetic tool.
