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.
Whereas PLA is known to have low melt strength and does not show strain hardening, co-agent modification of PLA led to substantial strain hardening, suggesting improved melt strength. Improvement of melt strength and crystallization rate of polylactic acid and its blends... with medium-chain-length polyhydroxyalkanoate through reactive modification
