3D-printed foam outperforms standard materials

Apr. 27, 2016 -  
Lawrence Livermore National Laboratory (LLNL) material scientists have found that 3D-printed foam works better than standard cellular materials in terms of durability and long-term mechanical performance. Foams, also known as cellular solids, are an important class of materials with applications...

New 3D printer unlocks 'mind-blowing' possibilities with electronics manufacturing

Mar. 22, 2016 -  
Installation of a highly advanced 3D printer for electronics at Lawrence Livermore National Laboratory has opened the door for creating miniature circuits on surfaces and substances that could never be used before. The Optomec Aerosol Jet 500 system, which became operational in January, is capable...

Researchers 3D print ultralight supercapacitors

Feb. 9, 2016 -  
For the first time ever, scientists at Lawrence Livermore National Laboratory and UC Santa Cruz have successfully 3D-printed supercapacitors using an ultra-lightweight graphene aerogel, opening the door to novel, unconstrained designs of highly efficient energy storage systems for smartphones,...

Researchers 3D-print with reactive materials

Dec. 16, 2015 -  
Reactive composite materials are everywhere, from the life-saving air bags in your car to the dazzling pyrotechnics in Fourth of July fireworks. But one of the main drawbacks to using these materials has been the unpredictability of their reactions. Historically, the way to alter the performance in...

Engineer develops 'leap forward' with 3D-printer

Dec. 11, 2015 -  
Lawrence Livermore Lab engineer Bryan Moran wasn’t necessarily looking to improve on 3D printing technology when he moved over to Additive Manufacturing three years ago, but he may have done just that. Moran’s creation, a new take on a process called projection micro-stereolithography, which uses...

Researchers 3D print 'living' blood vessels

Dec. 3, 2015 -  
The cardiovascular system is a complex web of tens of thousands of miles of arteries, capillaries and veins, branching throughout the body like tributaries of a great river. And now, researchers at Lawrence Livermore National Laboratory are recapitulating this intricate network using an emerging...
