Sentences with phrase «photon lithography»
Jan. 3, 2018 - Lawrence Livermore National Laboratory (LLNL) researchers have discovered novel ways to extend the capabilities of two - photon lithography (TPL), a high - resolution 3D printing technique capable of producing nanoscale features smaller than one - hundredth the width of a human hair.

Through the two - photon lithography (TPL) 3D printing process, researchers can print woodpile lattices with submicron features a fraction of the width of a human hair.
«Most researchers who want to use two - photon lithography for printing functional 3D structures want parts taller than 100 microns,» said Sourabh Saha, the paper's lead author.
Two - photon lithography typically requires a thin glass slide, a lens and an immersion oil to help the laser light focus to a fine point where curing and printing occurs.
In the paper, LLNL researchers describe cracking the code on resist materials optimized for two - photon lithography and forming 3D microstructures with features less than 150 nanometers.
«In this paper, we have unlocked the secrets to making custom materials on two - photon lithography systems without losing resolution,» said LLNL researcher James Oakdale, a co-author on the paper.
