Virginia Tech lab 3D prints a liquid metal composite to guide heat, boost thermal conductivity 40x — the nozzle stretches gallium-indium droplets inside soft silicone, can also create self-healing traces
Virginia Tech graduate student Hugh Grennan mixed eutectic gallium-indium (EGaIn) into uncured polydimethylsiloxane (PDMS) silicone in a “3D Printing LIQUID METAL!” video on the 3D Printing Nerd YouTube channel hosted…
