Students get a taste of Lab machinist work
Foothill High junior Lauren Graham has wanted to be an engineer since she took a class in eighth grade. Still undecided about her precise career path, she wants to expand her knowledge base and learn about all aspects of manufacturing. After seeing the many milling and welding machines, lathes and precision tools used at Lawrence Livermore National Laboratory (LLNL), and…
New open-air facility will be testing ground for autonomous drones, vehicles and robots
The multicopter drone’s blades whirred, lifting it off the ground with a distinct hum, kicking up dust and propelling the craft through its preprogrammed flight path. The drone’s operators gazed at their laptop screens, closely monitoring the performance of the drone’s sensors while it carried out its maneuvers. Carrying a payload for the Department of Defense, the drone…

New facilities to support stockpile stewardship
Leadership from Lawrence Livermore National Laboratory (LLNL), the National Nuclear Security Administration (NNSA), Livermore Field Office (LFO) and contractor Hensel Phelps broke ground earlier this month on the Applied Materials and Engineering (AME) campus at LLNL. The groundbreaking was for the start of new building construction in the 2200 block of the Laboratory and…
High-powered laser diodes can reduce residual stress in metal 3D printed parts
In 3D printing, residual stress can build up in parts during the printing process due to the expansion of heated material and contraction of cold material, generating forces that can distort the part and cause cracks that can weaken or tear a part to pieces, especially in metals. Researchers at Lawrence Livermore National Laboratory (LLNL) and the University of California,…
NFL comes to Lab to hear latest on TBI research
Officials from the National Football League visited Lawrence Livermore National Laboratory (LLNL) recently to hear how the Department of Energy’s (DOE) national laboratories are using high-performance computing and artificial intelligence to advance scientific understanding of traumatic brain injury (TBI). San Francisco 49ers chairman John York and NFL Executive Vice…
LLNL scientists use X-ray imaging, simulations to mitigate the defects in metal 3D-printed parts
Lawrence Livermore National Laboratory (LLNL) researchers, along with scientists at the SLAC National Accelerator Laboratory (SLAC), have discovered a solution to a major type of defect in metal 3D-printed parts. Combining high-performance computer simulations with X-ray imaging of the laser powder-bed fusion (LBPF) metal additive manufacturing process obtained with SLAC’s…
New call for HPC4EnergyInnovation proposals
The Department of Energy (DOE) and Lawrence Livermore National Laboratory (LLNL) today announced the spring 2019 call for proposals for the High Performance Computing for Energy Innovation (HPC4EI) Program, including three of its pillar programs. Managed by LLNL in partnership with other national laboratories, the HPC4EI program aims to provide industry with HPC expertise…
HPC4Manufacturing Program names four awardees for latest round of DOE funding
The High Performance Computing for Manufacturing Program (HPC4Mfg) today announced the recipients of $1.2 million in federal funding for four public/private projects aimed at solving key manufacturing challenges in steelmaking and aluminum production through supercomputing. The summer 2018 HPC4Mfg call for proposals, the sixth overall for the program, had a special focus —…
LLNL/UCSF-developed implants enable unprecedented recordings of brain activity
Lawrence Livermore National Laboratory (LLNL) scientists, working with researchers at University of California, San Francisco (UCSF), have developed a novel system for recording widespread brain activity, using high-density implantable devices to collect real-time data over longer timescales and across multiple areas of the brain. The new platform, as recently reported in…
New multibeam metal 3D printer testbed to understand laser-material interactions
Lawrence Livermore National Laboratory (LLNL) scientists and engineers have created the first research-grade, open-architecture multibeam metal 3D printer and are developing advanced diagnostics to understand the mechanics behind the multibeam process under a project funded by the Air Force Research Laboratory. To address the need for larger builds and faster print times,…
Researchers look to computing's past to unlock 3D-printed mechanical logic gates for the future
Taking a page from the past, Lawrence Livermore National Laboratory scientists and engineers are combining mechanical computing with 3D printing as part of an effort to create "sentient" materials that can respond to changes in their surroundings, even in extreme environments that would destroy electronic components, such as high radiation, heat or pressure. Original…
Going deep: Lab employees get an introduction to world of machine learning, neural networks
Deep learning is one of the most popular and widely used machine learning methods due to its success with autonomous vehicles, speech recognition and image classification, to name a few emergent technologies. But what exactly is deep learning, and how can it best be applied to Lab projects? Lawrence Livermore National Lab (LLNL) employees discovered the answers during a…
3D printing method creates objects in one piece
It looks like something you might find aboard the Starship Enterprise. A projector beams a three-dimensional video into a container of photosensitive resin. The video plays while the container rotates for a few minutes — then the fluid drains, leaving behind a complete, fully formed 3D object. Though it seems like science fiction, it’s not, thanks to scientists and…
Playing video games may help researchers find personalized medical treatment for sepsis
A deep learning approach originally designed to teach computers how to play video games better than humans could aid in developing personalized medical treatment for sepsis, a disease that causes about 300,000 deaths per year and for which there is no known cure. Lawrence Livermore National Laboratory (LLNL), in collaboration with researchers at the University of Vermont,…
Lab develops metamaterials that change mechanical properties under magnetic fields
Lawrence Livermore National Laboratory (LLNL) researchers have introduced a new class of metamaterials that can nearly instantly respond and stiffen 3D-printed structures when exposed to a magnetic field, a development that could be applied to next-generation helmets, wearable armor and a host of other innovations. The Lab-developed "field-responsive mechanical…
