TEMPERATURE

Summary from the TLDR newsletter

A new type of gel allows 3D printers to print heat-sensitive electronics. It enables the 3D printing of metal objects at room temperature. The gel temporarily turns a metal alloy into a liquid-metal state - it becomes rigid and highly electrically conductive after it is left to dry. It can create objects that can change shape in a predictable fashion if heat is applied while it is drying, allowing for the production of items with complex 3D shapes that are easier to print as a flat pattern.
