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...

Lawrence Livermore reinventing metal 3D printing with new direct writing process

Mar. 30, 2017 -  
Metal 3D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations. Parts produced using selective laser melting (SLM) and other powder-based metal techniques...
