| Summary |
When the earliest additive manufacturing (AM) technologies were developed in the 1980s and 1990s, their primary application was for the rapid manufacturing of prototypes. In the last decade, however, AM has rapidly emerged as a legitimate manufacturing process for a range of applications beyond prototyping, from tooling to end-use functional part production. Aerospace companies of all sizes have realized this earlier than most, and today, approximately 15% of all revenue generated in the AM industry can be traced back to aerospace applications [1]. There are a wide range of AM processes to choose from, broadly classified into six categories that between them span metals, polymers, ceramics, and biomaterials [2]. The one thing common to these technologies is a layered approach to building a part that uses an energy source such as light, heat, or an electron beam to convert a raw material such as a powder, filament, or resin into a part. |

Companies may have several strategic reasons for choosing to pursue AM, three of which are cost reduction, lead time reduction, and supply chain simplification. All these reasons stem mostly from an essential aspect of AM--that parts are manufactured layer-by-layer from raw materials and do not need tooling or preformed stock materials. In addition to these drivers, AM processes enable an inherently greater amount of design freedom. In the coming decades, the growth in AM will likely be driven by production parts that leverage this increase in design freedom to manufacture parts of higher performance and improved material utilization. Contrary to popular opinion, however, AM processes do have their constraints and limitations--not everything can be manufactured with AM, and even when it is feasible, not everything should. Finally, even if a part can and should be manufactured with AM, it is important to truly appreciate the design possibilities enabled by AM to maximize the performance, life-cycle cost, and sustainability benefits the technology has to offer--in other words, to understand how we can design for this technology to truly maximize its potential. |

In the following sections, considerations for AM are first presented that address the appropriateness (should) and feasibility (can) of using AM for manufacturing of parts and tooling. This is followed by a discussion of four different design concepts (how) that are ideally suited for AM technologies to exploit, which tend to drive the value proposition of using AM higher. The ten papers included in this compilation have been selected since they embody these ideas--while some of these papers were published before AM technologies were widespread, they are, nonetheless, a study of how designers in previous generations had to accommodate stringent design constraints. |
