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.
That is, ionic compounds will only convert from the solid state to the liquid state at high temperatures. The melting point of NaCl is 804 Â°C; the melting point of calcium carbonate (the main ingredient in limestone) is 1339 Â°C. Molecular solids contain molecules.
