Various methods are disclosed for additively manufacturing a feedstock material to create an AM preform, wherein the AM preform is configured with a body having an internal passage defined therein, wherein the internal passage further includes at least one of a void and a channel; inserting a filler material into the internal passage of the AM preform; closing the AM preform with an enclosure component such that the filler material is retained within the internal passage of the AM preform; and deforming the AM preform to a sufficient amount to create a product having an internal passage therein, wherein the product is configured with wrought properties for that material via the deforming step.

Methods of producing wrought products with internal passages

A tie down assembly adapted to be installed within a structure includes a cup and a plate fastened removably to the cup by fasteners. The cup includes a first sidewall, an interior portion, and a plurality of seats that extends within the interior portion. The plate an aperture to receive tie down connectors. The plate includes a plurality of tabs. The plate is positioned within the interior portion of the cup and rests on the seats. When the plate requires repair or replacement, it may be removed from the cup by unfastening the fasteners without the need to remove the cup from the structure. Each of the tabs of the plate is positioned within a space between adjacent pairs of the seats of the cup and is adapted to engage the seats of the cup so as to inhibit rotation of the plate relative to the cup.
