PLA (Polylactic Acid)

PLA is a starch based plastic which can be made from a range of plants. Some of the most common sources are cornstarch, tapioca root and sugar cane.  PLA is currently the greenest material you can use in your 3D printer. In 2010, PLA was the second most important bioplastic of the world in regard to consumption volume. Left to break down, PLA reverts to lactic acid and is classified as being biodegradable.  PLA is more brittle than ABS and parts made from it have a harder surface than ABS. PLA filament is available in a multitude of colours, unlike ABS, PLA is translucent by nature and so many translucent colours are available.  PLA comes in two standard thicknesses. 1.75mm and 3mm

Softens at 50ᵒC (also known as the “glass transition” temperature)

Melts at 60ᵒC

It can be extruded at 160ᵒC

It needs to be extruded at 210-230ᵒC to bond properly to the previous layer.

Bed temperature should be around 60ᵒC

Bed preparation can be done with a glue stick.

PLA is soluble in sodium hydroxide, commonly known as caustic soda which is the basis for many drain cleaning products.

PLA does not offer the same properties as ABS in being able to be glued together.  Joining PLA parts needs to be done with another, separate adhesive.  PLA will also display “stringing” when being printed to a larger extent than ABS.  Stringing can be minimised by setting the “retract” on the extruder to the correct value.  This function will withdraw the filament momentarily and prevent the nozzle from drooling on non-print movements.  Due to its relatively low glass transition and melting temperatures, PLA is not suitable for making objects that could be exposed to heat.  A PLA part could easily distort if left in a hot car for example.
