Abstract

Embodiments of the disclosure relate to the aligning of a melting beam source in an additive manufacturing (AM) system. Methods of the disclosure may include forming a first test article and a second test article of different shapes on a build plate. The method further includes measuring a vertical scale, vertical alignment, horizontal scale, and an alignment of the melting beam source using the first and second test articles. The method includes determining whether one of the vertical scale, the vertical alignment, the horizontal scale, or the horizontal alignment of the melting beam source is not within a corresponding tolerance of a target specification. If at least one of the vertical scale, the vertical alignment, the horizontal scale, or the horizontal alignment is within the corresponding tolerance, the method includes adjusting the melting beam source of the AM system to align the melting beam source to yield the target specification.
