Additive manufacturing (AM) technologies feature the selective addition of material, commonly in a layer-wise fashion, governed by volumetric digital process instructions to produce three dimensional structures. These manufacturing technologies are capable of processing metal, polymer, composite, and ceramic materials. Compared to other manufacturing technologies, AM presents several benefits, including lightweight structures (lattices, triply periodic minimal surfaces, and other organic shapes), consolidation of parts, limiting necessity for tooling, and lead time reduction. These benefits present potential to augment manufacturing productivity, yield, and cost. For these reasons, AM has been considered for a variety of aviation, automotive, marine, energy, space, and defense applications. AM has also challenged the way in which manufacturing technologies are selectively utilized. AM has shown substantial merit to support rapid testing and evaluation of novel design concepts. The merits of AM for product development have been realized for the manufacturing of test equipment, jigs, fixtures, as well as test parts. AM also offers the ability to impact product life cycle cost as a repair technology. The session will feature a variety of key topics which detail the current state of AM technologies, recent innovations, and future trends.
Key topics to be covered include:
- AM design methods and tools
- AM materials development – Testing, characterization, and modeling of metal, polymer, composite, ceramic, and graded materials
- AM process development – novel AM technologies, advanced process controls, AM hardware and software advancements, hybrid AM technologies, post-processing (heat treatment, finishing, joining, coating), and modeling
- Product qualification and certification
- Monitoring and inspection technologies – process health monitoring, in-situ process monitoring, and ex-situ inspection (NDE)
