Abstract: The demanding and ever-evolving missions of the Department of Energy call for increased responsiveness to the mission ‘pull’ while staying on the cutting edge of scientific advancements and anticipating programmatic needs through a technological ‘push.’ In this talk I will give an overview of activities in the Materials Science Division at Lawrence Livermore National laboratory and describe how these efforts feed into our latest developments in advanced manufacturing. Along with highlights of work in polymer chemistry, actinide science and energetic materials, I will focus on work involving the materials science of metal 3D printing which represents one of many growth areas of the lab. Prepared by LLNL under Contract DE-AC52-07NA27344.
