How to Specify Additively Manufactured Aluminum Parts

Specifying “Additively Manufactured” (AM) aluminum is challenging and involves an approach guided by ASTM and ISO standards that require more engineering decisions throughout the manufacturing process than typically encountered with a purchased component. With this additional complexity, ISO/ASTM 52910 guides a designer to first establish the general AM potential of the part, which involves material, build size, and a host of feature trade-offs. Next, the designer must select from several AM processes that can provide a range of properties for a given material.

Addressing Foreign Object Damage in Manufacturing

Addressing Foreign Object Damage in Manufacturing

Foreign Object Damage (FOD) is a major concern in the aviation, space, and defense industry, as well as other manufacturing industries.  It is interesting that no FOD requirements are noted in the AS9100D standard.  While there is a large amount of infomation and guidance available in the AS9146 FOD Standard.
