PLA, polylactic acid, is a fully biodegradable polymer resulting from the fermentation of sugar or starch as a result of synthesizing lactic acid bacteria.
PLA is used in food packaging and in the manufacture of many injected, extruded or thermoformed articles.
The PLA is the material used by the 3D printer at l’Etablisienne.
