Photonic Sintering System to Investigate AI-Assisted Design of Additive Manufacturing Processes for
Abstract
Summary/AbstractPublicly ReleasableONR PO: Dr. Antti MakinenCode: 332This proposal seeks to purchase a cutting-edge, photonic sinter,ing system capable of rapidlyceramizing, sintering, and/or crystallizing various pre-ceramic precursors, powders, and films toadvanc,e the state-of-the-art in additive manufacturing of ceramics and other end uses of interestto the DoD. This photonic sintering syste,m includes units to support powder preparation andthermal analysis that when combined with data informatics will accelerate iterativ,e discovery ofnew process routes for 3D printing of ceramics and other inorganic materials. The flash-lampbasedphotonic sintering to,ol, which is capable of heating surface layers to >1200 ?C within amatter of tens of microseconds while maintaining substrate temper,atures to below 300 ?C, willalso enable greater integration of high-performing ceramic components with temperature-sensitivesubstrat,es like doped semiconductors and flexible polymer sheets. These advances inceramicprocessing will have far-reaching applications of,interest to the DoD, including but not limited tometamaterials, smart antennas, acoustic transduction devices, power generation, ene,rgy storage,RF surveillance, functional optical coatings, and materials for thermal and chemical extremes.Specifically, this photoni,c sintering system will be used extensively by a currently funded DoDresearch program to develop new processing conditions and chemi,stries to achieve rapid sinteringof ceramic powders commensurate with the requirements for additive manufacturing. Today,additive ma,nufacturing of ceramic components remains in its infancy. While polymers are readilyprinted into 3D components, ceramics remain diff,icult to additively manufacture, yet additivemanufacturing of ceramics would be of great use in numerous structural and functionalap,plications of interest to the DoD. While preceramic polymers can be printed and ceramized intoceramic components, most are based on,silicone chemistries, limiting final ceramic chemistries tosilicates. Expanding additive manufacturing capabilities to other structu,ral and functionalceramics including refractories, transformation-toughened ceramics, catalysts, ion conductors,piezoelectrics, ferr,oelectrics, ferromagnetics, electro-optics, and others would open entirely newopportunities for structural and functional systems of, interest to the DoD and commercial use. Newpowder morphologies, powder chemistries, additives, and thermal processing conditions co,mbinedwith artificial intelligence (AI) and materials informatics must be leveraged to achieve these loftygoals. This photonic sinte,ring system will enable rapid development of these process conditionsand significantly advance the state-of-the-art in additive manu,facturing of ceramics. The proposedphotonic sintering system will also enhance the research output of other currently funded DoDprog,rams at Georgia Tech including in 2D materials, thermal management, and ultralow voltageferroelectric transistors. In total, this sy,stem will impact over $23,000,000 in currently fundedDoD projects at Georgia Tech and benefit over 20 different research groups, edu,cating dozens ofgraduate students and postdoctoral researchers in flash lamp annealing technology for photonicsintering and material,s manufacturing. Approved for public release.
