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.
You can get slightly higher quality surface finish with ABS over PLA, but on the whole PLA works better in the machine, requiring lower temperatures and giving stronger, more hard-wearing products. It does have a slightly higher coefficient of friction in the drive and transport than ABS, but this is more than compensated for by its lower viscosity when molten. This means lower pressure in the melt chamber and hence a lower driving force. PLA filament can break when stored under stress:
