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.
By Larry West. Polylactic acid (PLA), a plastic substitute made from fermented plant starch (usually corn) is quickly becoming a popular alternative to traditional petroleum-based plastics.nother downside of PLA is that it is typically made from genetically modified corn, at least in the United States. The largest producer of PLA in the world is NatureWorks, a subsidiary of Cargill, which is the worldâs largest provider of genetically modified corn seed.
