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...

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

Jul. 18, 2016 -  
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...

3D printing could revolutionize laser design

Jul. 18, 2016 -  
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...

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

Jun. 29, 2016 -  
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...

Lab engineers garner DOE tech transfer awards

Jun. 28, 2016 -  
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...

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...
