3D laser printing in ambient conditions is demonstrated by M. Zenou and co‐workers on page 4082. The fabrication of the 3D structure consists of overlapped copper droplets a few tens of femtoliters each. The fast solidification of the molten metal droplet as it lands reduces its spreading, allowing the fabrication of high aspect‐ratio structures. The letters shown in the image are 50 μm wide and are gradually of a higher height from 40 μm (‘s’) to 190 μm (‘l’). The image was taken with tilt of 55 degrees.
