PLA is harder than ABS, melts at a lower temperature (around  180Â°C to 220Â°C), and has a glass transition temperature between 60-65 Â°C, so is potentially a very useful material. It does exhibit higher friction than ABS however which can make it difficult to extrude and more susceptible to extruder jams.
Gallium is not the only metal that melts into a liquid near room temperature or body temperature. Francium, cesium, and rubidium also would melt in the palm of your hand. However, you seriously don't want to attempt this demonstration with any of them! Francium and cesium are radioactive.
