We review recent results and methods at NSLS-II applicable to additive manufacturing.
In this article, we describe some of the additive manufacturing capabilities that have been implemented on these beamlines, including in-line 3D printers for Continuous-flow Direct Writing (CDW), Fused Filament Fabrication (FFF) printing, and an instrument for Electrospray Deposition (ESD). We also describe a development program in autonomous experimentation that will be critical for addressing the complexity involved in optimizing additive manufacturing processes and materials. These capabilities and approaches have been co-developed in partnership with Brookhaven Lab's Center for Functional Materials (CFN) as well as collaborative users from universities (Stony Brook and Yale University), government labs (Air Force Research Laboratory, National Institute of Standards and Technology, Lawrence Berkeley National Laboratory), and industry (Henkel Inc.).
