AM represents a new paradigm and offers a range of opportunities for design, functionality, and cost. Opportunities for many industries largely remain to be identified. AM is a dynamic, evolving field with many researchers and industrial users continually improving the state-of-the-art, while moving to develop and qualify combinations of material and process for commercial exploitation. Factors increasing the potential suitability for commercial and government applications include: - Nominally unmanufacturable components - High added value, long lead-time items - Repair and replacement of legacy aircraft components However, much work is required across many fields to realize the promise of AM and overcome the barriers of cost for materials property data, qualification, and certification costs, particularly for aerospace parts. Some items on the horizon that will overcome current barriers and enable this promising technology to be deployed in production include: Development of design databases in MMPDS to allow aerospace designers to select the AM process with confidence. Use of modeling and simulation at the design stage to optimize for performance at an early stage and compress the development timeline in the manufacturing process. Established industry standards that facilitate the business processes for parts production. Education and training for designers, engineers, and technician staff. Lower cost machines (ubiquitous like CNC machine tools), although some posit that the cost of AM machines is not necessarily an impediment to those who purchase multi-million dollar CNC equipment. Open architecture machines with embedded sensors and controls for parts certification and reduced cost of nondestructive inspection. Development of the supply chain leading to the commoditization of AM, which will drive the need for lower cost processes. AM in space and mission to Mars based on the work of NASA and others. Morphing UAVs and MAVs with hybrid metallic/composite structure and embedded Direct Write electronic circuitry. Mobile parts hospitals for field use by the Army, Navy, and Air Force. Combined functionality and functionally gradient materials.
