Preliminary design setup and experimental results of laser sintering for use in aerosol jet printing

It is imperative to understand the application of emerging advanced manufacturing techniques to nuclear related capabilities. The Advanced Manufacturing thrust of the In-Pile Instrumentation Initiative seeks to apply techniques such as aerosol jet printing to allow for manufacturing of novel sensor designs. As part of this thrust, a laser sintering system is being developed. The preliminary design allows for benchtop experiments that are controlled with a manual stage. The preliminary results did not appear to achieve sufficient temperatures to sinter the specimen, and temperatures were not accurately measured by the IR camera. A calibration to link silver emissivity with temperature must be performed in order to quantitatively measure temperatures with the IR camera. This calibration will be performed, and a second sintering experiment performed in detail to determine required laser exposure times and temperatures to achieve sintering with the system. Future updates for the system include a higher resolution lens for the IR camera to allow for higher magnification temperature observations, as well as a motorized stage and control framework to link the stage movements to the specimen geometry and desired exposure time during the sintering process.
