Virginia Tech 3D Prints Liquid Metal Composite for Heat
5 min read
Virginia Tech researchers 3D printed a liquid metal composite that guides heat 40 times better than plain silicone. The material, eutectic gallium-indium mixed into PDMS, forms droplets that stretch to conduct heat directionally. A 2025 paper measured 9.9 W/mK thermal conductivity. The lab demonstrated self-healing electrical circuits and points to custom heat sinks and stretchable wearables as applications.
