This talk will describe some of the many types of 3D printing or additive manufacturing (AM) that we use for research at Lawrence Livermore National Laboratory (LLNL). From printable cars, glass optics, to wearable electronics, there are many different applications that can benefit from 3D printing, and so we use 3D printing to turn ideas a reality. This work is part of teams of engineers, materials scientists, and more, all working together to print objects previously not possible. While much of my work is making materials for printers, we also use multimaterial 3D printers as a tool to speed up and automate materials advancement. We currently use this automated screening system to look for better and safer battery materials. This talk will look to the future of AM, and how LLNL is working to meet these challenges to re-design our world of things.



Johanna Schwartz received a B. S. in Chemistry and Biology from Bard College, M. S. in Organic Chemistry from University of Washington, and Ph. D. in Organic Chemistry from University of Wisconsin, Madison. She is currently a staff scientist in the Materials for Energy and Climate Security group at LLNL. She works as a chemistry and materials expert to improve Additive Manufacturing processes. She is creating an automated, high-throughput materials screening platform centered on improving the ionic conductivity of polymer electrolytes for safer Li-ion batteries. 


Michell Marufu received a B. S. in Chemistry from Whitworth University and a M. S. in Polymer Chemistry from University of Oregon. She first joined LLNL as a graduate intern in the Materials Science Division working on the development of lithium based solid polymer electrolytes for battery applications. She became a staff scientist in 2022, her work focuses on producing sustainable fuels and high-order carbon products, which can be integrated into industrial manufacturing processes. 


Stan Hitomi received a B. S. in Biology from UC Berkeley and a Masters in Athletic Administration from St. Mary's College. He retired in 2020 after 31 years as a teacher, principal and district administrator for the San Ramon Valley Unified School District. He is a Carnegie Scholar, served on the Community Advisory Panel for Station KQED, co-chair for the Teaching and California’s Future Task Force, and founding chair for the California Teacher Advisory Council. Stan has been at LLNL for over 25 years as an intern, faculty scholar, and former Director of the Edward Teller Education Center.
