Polylactic acid is a bio-degradable polymer that can be produced from lactic acid, which can be fermented from crops such as maize. This makes it an ideal candidate for use in certain energy rich, cash poor areas of the world.

Polylactic acid is a bio-degradable polymer that can be produced from lactic acid, which can be fermented from crops such as maize. This makes it an ideal candidate for use in certain energy rich, cash poor areas of the world. PLA is harder than ABS, melts at a lower temperature, around 190° and has a glass transition temperature between 60°-65° 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 is the ideal material for 3D printing. It is dimensionally stable, so there is no need for a heated bed. It is relatively inexpensive, and is not hard to source in filament form. 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. Source: http://reprap.org/wiki/PLA
