Revolutionary changes to materials and structures are now possible with 3D printing, bringing concepts that were previously only imagined into reality. In conventional manufacturing processes, such as machining, material is typically removed. Additive manufacturing (AM), commonly known as 3D printing, is a breakthrough technology which fabricates components by adding material layer by layer from the bottom up. This allows for the creation of highly complex and previously unrealizable structures which have radically improved performance and capability such as high strength and low weight. Additionally, these technologies enable mass customization and rapid design iteration. For example, medical implants can be designed to fit a specific patient and rapidly printed. This presentation will discuss 3D printing technologies and how they work, as well as how to design for these processes, create the feedstock materials, and test the performance of the products. At LLNL, we are working with existing AM technologies and materials, as well as inventing our own, and pushing the boundaries of size scale, material composition, and geometric complexity.

Dr. Eric Duoss

Dr. Eric Duoss is currently an Engineer at Lawrence Livermore National Laboratory (LLNL), where he conducts research in the areas of advanced materials, manufacturing and micro-architected design. At LLNL, Eric is responsible for developing novel additive manufacturing processes and feedstocks, with particular focus on creating designer micro-architectures for mechanical, thermal, and functional properties for applications in the fields of transportation, energy, aerospace, defense, and others. Prior to joining LLNL, Eric was a postdoctoral and graduate research associate at University of Illinois, where he focused on developing new materials and applications for three-dimensional printing technologies for a broad array of applications, including photonic crystals, sensors, and antennas. Eric has a Ph.D. in Materials Science and Engineering from University of Illinois and dual B.S. degrees in Chemistry and Mathematics from St. Norbert College in Wisconsin.

Dr. Christopher Spadaccini

Christopher M. Spadaccini, Ph.D., is currently the Director of the Additive Manufacturing Initiative at the Lawrence Livermore National Laboratory (LLNL) as well as the leader of the Center for Engineered Materials and Manufacturing. He has been working in advanced additive manufacturing process development and architected materials for the last decade and has over 30 publications and several dozen patents awarded and pending. Dr. Spadaccini founded several new fabrication laboratories at LLNL for process development focused on micro and nano-scale features and mixed material printing. He received his B.S., M.S., and Ph.D. degrees from the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology (MIT) in 1997, 1999, and 2004 respectively and has been a member of the LLNL technical staff for over 12 years. He has also been a lecturer in the Chemical, Materials, and Biomedical Engineering Department at San Jose State University where he taught graduate courses in heat, mass, and momentum transfer.

Julie Jackson

Julie Jackson received her B.S. in Mechanical Engineering from UC Davis in 2013. Julie graduated from Livermore High School in 2008 and went to Las Positas Community College for 3 years before transferring to UC Davis. She started as a summer intern at LLNL in 2012. In 2014, she was hired as a Staff Engineer working in the Center for Engineered Materials and Manufacturing. Her research interests are in 3D printing, metamaterials, and mechanics of materials. Julie is currently pursuing a M.S. degree from UC Davis in Mechanical and Aeronautical Engineering as part of LLNL’s "Distance Learning Program," which allows employees to complete graduate engineering and computer science programs over the internet.

William Smith

Originally hailing from the Chicago area,  William Smith obtained his B.S. in Engineering Mechanics from the University of Illinois at Urbana-Champaign in 2013.  Will started at LLNL as an Engineering intern in the summer of 2012 working in microfluidics. Since being hired as a Staff Engineer in 2014, he has ventured into the design of 3D printed metamaterials and  studying their mechanical properties.  While working at LLNL, Will is concurrently pursuing his M.S. degree in Mechanical Engineering at UC Davis through the lab's "Distance Learning Program".

Melody Golobic

Melody Golobic received her B.S. in mechanical engineering from Cal Poly SLO in 2014. During her time at Cal Poly, she was involved in designing nanosatellites for the CubeSat program and became interested in materials for harsh environments. She started working at LLNL as a summer intern in 2013; in 2015, she was hired as a staff engineer with the Center for Engineered Materials and Manufacturing. Melody is currently pursuing a Ph.D. in Materials Science and Engineering from UC Davis through the Distance Learning Program. Her research focuses on colloidal suspensions and the surface science behind creating 3D-printable inks.

Dean Reese

Physics and Biology Teacher
Tracy High School

Dean Reese received his undergraduate degree in physics from the University of Massachusetts in Amherst. Currently, he is the Science Department Chairperson at Tracy High School and has been teaching there since 2002. He teaches IB Physics, Conceptual Physics, and ELL Conceptual Physics. He has been a Master Teacher for LLNL’s Education Program since 2007 and currently instructs in the Computer Simulation Teacher Research Academy. Dean has co-presented with various scientist in many Science on Saturday Presentations. In 2006, Dean had a DOE Academies Creating Teacher Scientists internship where he interned for 3 consecutive summers at the Center for Accelerator Mass Spectrometry at LLNL. In 2011, Dean was awarded the Cortopassi Family Foundation Excellence in Science Teaching Award. He is a dedicated advisor for the Tracy High Earth Club, Scientifically Speaking Club, and Computer Programming Club. Dean is a master instructor for the SIMMS (Secondary Integration of Modeling in Math and Science) Project with the intent of developing computer modeling skills for high school science and math teachers within the San Joaquin County. Prior to becoming a teacher Dean was a soldier in the United States Army National Guard.
