LLNL finds reason behind defects in 3D printing

Aug. 1, 2017 -  
High-speed images of a common laser-based metal 3D printing process, coupled with newly updated computer models, have revealed the mechanisms behind material redistribution, a phenomenon that leads to defects in printed metal parts, Lawrence Livermore National Laboratory (LLNL) researchers reported...

Lab loans state-of-the-art 3D printer to Cal Poly

Jun. 7, 2017 -  
California Polytechnic State University (Cal Poly) San Luis Obispo engineering students now have access to the state-of-the-art in metal additive manufacturing and the ability to perform contracted work for Lawrence Livermore National Laborator y (LLNL), thanks to a new Selective Laser Melting (SLM...

NIF technology could revolutionize 3D printing

May. 25, 2017 -  
A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility ( NIF ) can be used to 3D print metal objects faster than ever before, according to a new study by Lawrence Livermore researchers. A team of Lab scientists report the findings in...

LLNL and LBNL researchers explore more energy-efficient solutions for paper industry

May. 16, 2017 -  
If you had to name the industries in the United States that use the most energy, paper manufacturing probably wouldn't immediately come to mind. In fact, the paper-making industry ranks third among the country's largest energy users, behind only petroleum-refining and chemical production, according...

Lawrence Livermore unveils 'heart-on-a-chip'

May. 11, 2017 -  
Prescription drugs have enabled millions of Americans with chronic medical conditions to live longer and more fulfilling lives, but many promising new drugs never make it to the human trials stage due to the potential for cardiac toxicity. Through "heart-on-a-chip" technology -- modeling a human...

DOE HPC4Mfg Program funds 13 new projects to improve energy technologies through HPC

May. 8, 2017 -  
A U.S. Department of Energy (DOE) program designed to spur the use of high performance supercomputers to advance U.S. manufacturing is funding 13 new industry projects for a total of $3.9 million. The High Performance Computing for Manufacturing (HPC4Mfg) Program unites the world-class computing...

Lab developed aerodynamic devices improve tractor trailer fuel efficiency

May. 8, 2017 -  
Lawrence Livermore National Laboratory ( LLNL ) researchers, as part of a Navistar SuperTruck I team, helped design a new type of tractor-trailer truck that significantly improves fuel economy. The new SuperTruck vehicle achieved 13 mpg on public roads and a 104 percent freight efficiency...

Lab breakthrough in 3D printing of glass

May. 2, 2017 -  
Lawrence Livermore National Laboratory scientists and academic collaborators have demonstrated the synthesis of transparent glass through 3D printing, a development that could ultimately lead to altering the design and structure of lasers and other devices that incorporate optics. A team of LLNL...

Experiments validate models predicting failure modes in miniaturized lightweight structures

Apr. 5, 2017 -  
Lawrence Livermore National Laboratory (LLNL) researchers have adapted theoretical models to predict the failure behavior of miniaturized 3D lattice structures and have used advanced characterization techniques to demonstrate that these failures exist. Specifically, experiments showed a transition...

McCallen recognized by Chico State University

Apr. 4, 2017 -  
It's been more than three decades since Rose McCallen graduated from California State University, Chico , but in the intervening years she hasn't forgotten her alma mater. And just the other day, the university remembered - and honored - her. McCallen, who graduated from Chico State in 1980 with a...
