Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize integrated ribs to support thin walled annular structures. An annular wall fabricated using AM has a thickness less than 0.022 inches across a majority of a surface of the annular wall and a plurality of ribs having a thickness greater than 0.030 inches. The annular wall has a mean thickness less than 0.100 inches. The annular wall conforms to a surface of the component and a mean distance between the annular wall and the component is less than 0.080 inches.

Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize table support structures in the process of building objects, as well as novel table support structures to be used within these AM processes. The table support structures include a first leg portion extending vertically from a build platform; a platform portion including a horizontal top surface supported on the first leg portion; and a plurality of supports extending from the platform portion to a downfacing surface of the object.
