LLNL wins three R&D 100 awards

Lawrence Livermore National Laboratory researchers have garnered three awards among the top 100 industrial inventions worldwide for 2016. The trade journal R&D Magazine announced the winners of its annual awards, sometimes called the "Oscars of invention," Thursday at the Gaylord Convention Center in Washington, D.C. With this year’s results, the Laboratory has now…

Lab-developed hydrogen sensors put to the test at Southern California refueling stations

As hydrogen fuel cell cars become commercially available and hydrogen refueling stations slowly begin to proliferate throughout California, government agencies are turning to Lawrence Livermore National Laboratory to help detect leaks that could lead to fire. The South Coast Air Quality Management District (SCAQMD), the air pollution control agency for Orange County and…

3D printed metamaterial shrinks when heated

Members of Lawrence Livermore National Laboratory’s Additive Manufacturing Initiative are among a group of researchers who have developed 3D printed materials with a unique property -- instead of expanding when heated, they shrink. In a study published in the Oct. 21 edition of the journal Physical Review Letters, LLNL engineers, along with scientists from the University…

Scientists explore use of 3D printing to speed up target production for testing material strength

Advanced 3D printing promises to redefine manufacturing in critical industries such as aerospace, transportation and defense, and now, Lawrence Livermore National Laboratory is exploring the use of 3D printing to achieve unprecedented flexibility in producing "on-demand" targets for testing how materials behave under extreme conditions. Through an additive manufacturing…

LLNL to lead development of manufacturing training program for energy entrepreneurs

The "valley of death" can make or break a startup enterprise due to the cost and time involved in getting from prototype to profitability. To help clean technology entrepreneurs and engineers navigate across the chasm and make it safely to the other side, the Department of Energy’s (DOE’s) Office of Energy Efficiency & Renewable Energy (EERE) has announced the…

New study unlocks potential for ultra-lightweight and flexible 3D-printed metallic materials

Lawrence Livermore National Laboratory (LLNL) engineers have achieved unprecedented scalability in 3D-printed architectures of arbitrary geometry, opening the door to super-strong, ultra-lightweight and flexible metallic materials for aerospace, the military and the automotive industry. In a study published online July 18 in Nature Materials, LLNL engineers report building…

3D printing could revolutionize laser design

LLNL researchers are exploring the use of metal 3D printing to create strong, lightweight structures for advanced laser systems - an effort they say could alter the way lasers are designed in the future. In a Laboratory Directed Research and Development (LDRD) program, physicist Ibo Matthews and his team are experimenting with a new research-based metal 3D printer, one of…

'Sky's the limit' for latest graduates of the Laboratory's Machinist Apprentice Program

While he was working as a machinist in Oakland and taking classes at Laney College, Wesley Scoggins wanted to improve his skills to find a better job. In 2012, he answered a Craigslist posting for a slot in the Livermore Lab Engineering Directorate’s Machinist Apprentice Program. It was an opportunity he couldn’t pass up. "It’s really one of the only machinist…

Lab engineers garner DOE tech transfer awards

The Department of Energy (DOE) recently announced the selection of two proposals from Lawrence Livermore National Laboratory (LLNL) researchers for grants under the department’s Technology Commercialization Fund (TCF), a program intended to help promising energy technologies move from national laboratories to the marketplace. DOE awarded LLNL engineer Brian Guidry a $432…

Putting pressure on 3D-printed structures
