| Abstract Scope |
While working with NASA and the DoD the Open Additive (OA) team has gained extensive experience developing or using a wide range of in situ sensing modalities, some for commercial product development and some simply for physical process understanding. This talk will highlight the capabilities and limitations of a broad range of sensors, ranging from coaxial melt pool imaging to optical tomography to exotic spectroscopy systems. Trade-offs between different in situ sensing approaches will be discussed so the types of sensors chosen for a given application, and the rationale, can be understood. To conclude, the talk will show how users can access and use live in situ data streams, and ways in which in situ sensing data may be used in the future for R&D, quality assurance, and developing new AM processes. |
