Lawrence Livermore reinventing metal 3D printing with new direct...

March 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...

Lab employees author X-ray imaging book

March 28, 2017 - After three current and former Lawrence Livermore National Laboratory (LLNL) employees and a university professor found a need, they started down the long road to meet it. When the LLNL trio -- physicist Harry Martz, retired engineer Clint Logan and retired computer scientist Dan Schneberk -- and...

Engineer wins scholarship for women veterans

March 23, 2017 - U.S. Marine veteran Destiny Goddu has spent her whole life working with machines. As a young girl growing up in Livermore, she helped her father, a mechanic, disassemble and rebuild car engines and tinkered with auto parts in the family garage. After joining the Marines, she worked on missile...

The softer side of NIF hohlraums

March 17, 2017 - Considering that nothing precious comes from an online retailer without protective padding, could precision laser targets also benefit from similar high-tech swaddling? So far the answer is yes, for a group of scientists developing new target technologies for NIF that are intended to neutralize...
