  • Publication number: 20240091858
    Abstract: Various embodiments of the teachings herein include a method for fusing one or more cross sections in a powder layer for building one or more objects layer by layer with electron beam powder bed fusion. The method may include: pre-sintering only the cross sections in the powder layer by scanning the cross sections with a first line energy; and fusing the cross sections by scanning the cross sections with a second line energy. The second line energy exceeds the first line energy by at least a factor of 2.

  • Publication number: 20230302540
    Abstract: In summary, the teachings herein concern methods and/or systems for preheating a build plate for additive manufacturing with at least one energy beam emitting a power. In some examples, the method comprises controlling a power distribution (PXY) of the power (P) over dimensions (X, Y) of the build plate comprising: determining the power (P) of the beam based on a target temperature (TSET) for the base plate and determining the allocation of the power (P) to the dimensions (X, Y) based on a temperature distribution (?T) in the base plate.
