In Lawrence Livermore National Laboratory's latest study, a team of researchers led by Juergen Biener is studying the use of 3D printing for the production of targets to be used for testing material strength under extreme conditions. Using an additive manufacturing process known as two-photon polymerization direct laser writing, the team has produced millimeter-sized, low density foam reservoir targets with nanoscale features. Designed for material strength testing at the OMEGA laser in Rochester, New York, the targets are the first precision macroscopic parts to be fabricated with two-photon polymerization direct laser writing technology.
