METHODS AND THIN WALLED REINFORCED STRUCTURES FOR ADDITIVE MANUFACTURING

WIPO Patent Application WO/2018/005889

A3

The present disclosure generally relates to methods for additive manufacturing (AM) that utilize integrated ribs (224) to support thin walled annular structures (220). An annular wall (220) fabricated using AM has a thickness less than 0.022 inches (0,5588 mm) across a majority of a surface of the annular wall (220) and a plurality of ribs (224) having a thickness greater than 0.030 inches (0,762 mm). The annular wall (220) has a mean thickness less than 0.100 inches (2,54 mm). The annular wall (220) conforms to a surface of the component (210) and a mean distance between the annular wall (220) and the component (210) is less than 0.080 inches (2,032 mm).
