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.
Final strength is reached later. Reactive polyurethane hot melts yield rubbery and plastic cured films. Curing hot melts have the advantage that they can be applied at very low temperatures, 125 to 250 o F (50 to 120Â°C). In contrast, standard hot melts are applied at higher temperatures 250 to 470 o F (120 to 240Â°C).
