In freeze‐printing, the liquid metal alloy (EGaIn) is continuously dispensed and frozen along truly 3D curvilinear paths. The printed solid metal network is encapsulated in elastomers to form a flexible composite at room temperature. Freeze‐printing can be used to generate high density interconnects, analog circuitry, and antennae for flexible electronic devices. The findings on the fluidic, thermal, and mechanical aspects of freeze‐printing are presented.
