Putting pressure on 3D-printed structures

Jun. 27, 2016 -  
Through a series of dynamic compression experiments on additively manufactured (AM) structured lattices, a Lawrence Livermore National Laboratory team, supported by colleagues at Los Alamos National Laboratory, has found that the assemblies have unique properties not exhibited by disordered...

Purpose and sacrifice mark offsite assignment

Jun. 23, 2016 -  
When Daryl Boyer was asked to lend his technical expertise to help shape the future of the U.S. nuclear deterrent, he knew it meant relocating to Omaha, Nebraska, without his parents and children. But the challenge called him and the timing was right. He acted decisively. Boyer is an LLNL engineer...

Lawrence Livermore team improves 3D-printed graphene aerogel supercapacitors

Jun. 16, 2016 -  
Lawrence Livermore National Laboratory (LLNL) researchers, along with a team from UC Santa Cruz (UCSC), have devised a method for doubling the performance of 3D-printed graphene-based supercapacitors. The method, which involves sandwiching lithium ion and perchlorate ion between layers of graphene...

‘Human-on-a-chip’ could replace animal testing

Jun. 2, 2016 -  
Development of new prescription drugs and antidotes to toxins currently relies extensively on animal testing in the early stages of development, which is not only expensive and time consuming, it can give scientists inaccurate data about how humans will respond to such agents. But what if...

Lawrence Livermore discovery a ‘big step forward’ for metal 3-D printing process

May. 25, 2016 -  
Researchers at Lawrence Livermore National Laboratory (LLNL) have taken a major step toward answering a question plaguing a common metal 3-D printing technique: What interactions can lead to the porosity found in parts produced by laser powder-bed fusion processes? In a paper published in the May...

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...
