  • Method and apparatus for additive manufacturing of a component, and component manufactured in accordance with the method
    Patent number: 12691498
    Abstract: A method and an apparatus for additive manufacturing of a component are described. At least one powder is provided. A plurality of component layers of the component to be manufactured are produced, wherein at least one powder fraction of the at least one powder is deposited to produce a component layer by electrostatically charging the powder fraction, electrostatically charging a deposition unit at least in some regions and picking up the electrostatically charged powder fractions by means of the deposition unit, which is electrostatically charged at least in some regions, and transferring it to a deposition surface. Various powder fractions to be deposited to produce the component layers are electrostatically charged with different polarity.

  • Method and apparatus for additive manufacturing of a component, and component manufactured in accordance with the method
    Publication number: 20260001134
    Abstract: A method and an apparatus for additive manufacturing of a component are described. At least one powder (P2) is provided. A plurality of component layers (B1, B2, B3) of the component to be manufactured are produced, wherein at least one powder fraction (A3) of the at least one powder (P2) is deposited to produce a component layer (B3) by electrostatically charging the powder fraction (A3), electrostatically charging a deposition unit (7) at least in some regions and picking up the electrostatically charged powder fractions (A3) by means of the deposition unit (7), which is electrostatically charged at least in some regions, and transferring it to a deposition surface (F). Various powder fractions (A3) to be deposited to produce the component layers (B1, B2, B3) are electrostatically charged with different polarity.
