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.
PLA prints nicely directly to a very lightly oiled sheet of polycarbonate/Lexan. 1  Some tips for printing on Polycarbonate: 2  If you have trouble getting it to stick, try raising your extrusion temp a few degrees. At 185C I have no trouble, but at 180C it is almost impossible to get a good first layer.
