A fascinating and beautiful world of tiny structures Once a year, researchers from the SNI network submit their most impressive images of the nano and micro world to the Nano Image Award competition. These fascinating images are one way for the SNI team to generate interest in the nanosciences among a wide audience. This colorful crystal orientation map was one of the images to win the Nano Image Award in 2022. It shows 3D-printed (additively manufactured) stainless steel fol- lowing surface etching. This technique is used by researchers from the Paul Scherrer Institute to reveal melt pool tracks and thereby to gain a better under- standing of the relationship between 3D printing parameters and material structure.
