R. K. Kramer and co‐authors report a direct writing method for Ga‐In alloys based on an extrusion process. Liquid Ga‐In exposed to ambient conditions forms a Ga‐oxide skin, which governs the wetting dynamics and printability of Ga‐In alloys on silicone‐based substrates. The direct writing method and corresponding design algorithm developed on page 3501 lead to free‐standing liquid structures, which are applied to create stretchable and conformable electronic devices.
