Scientists create highly conductive metallic gel for 3D printing at room temperature

Posted by in categories: 3D printing, space travel

This metallic gel is made from a mixture of micron-scale copper particles suspended in water and a small amount of a liquid indium-gallium alloy.

The origins of three-dimensional (3D) printing can be traced back to the 1970s when Johannes F Gottwald patented the Liquid Metal Recorder. This device used continuous inkjet technology to create metal objects that could be removed and reused or melted down for printing again.

Since then, innovations in 3D printing have happened at an unprecedented speed, with the most recent reports of 3D-printed Lamborghini and 3D-printed rocket engines.
