A pure‐copper pillar with a height of 860 μm and a width of ca. 5 μm is shown in the inside back cover image. The pillar is printed by C. W. Visser, R. Pohl, and co‐workers as described on page 4087, using laser‐induced forward transfer (LIFT), in which droplets with a diameter of around 1 μm are ejected and can be stacked to yield pillars, lines, or more‐complex shapes. The results show that LIFT allows pure‐metal 3D printing in the micrometer‐size range, which has been a long‐standing challenge. The edge of the microscope slide on which the pillar is standing is still visible at the bottom. The insets show the top, center, and bottom of the pillar.
