This document gives requirements, guidelines and recommendations for using additive manufacturing (AM) in product design. It is applicable during the design of all types of products, devices, systems, components or parts that are fabricated by any type of AM system. This document helps determine which design considerations can be utilized in a design project or to take advantage of the capabilities of an AM process. General guidance and identification of issues are supported, but specific design solutions and processspecific or material-specific data are not supported. The intended audience comprises three types of users: designers who are designing products to be fabricated in an AM system and their managers; students who are learning mechanical design and computer-aided design; and developers of AM design guidelines and design guidance systems.
