Voir la source de PLA

Le PLA est un plastique biosourcé souvent à base d'amidon de maïs ou de pomme de terre, il est utilisé comme filament dans les imprimantes 3D [[RepRap]], ainsi que dans la vaisselle jetable du fait de sa compatibilité alimentaire. PLA est l'acronyme anglais d'acide polylactique. En comparaison du filament ABS, il est moins résistant aux chocs et à la pression.

L'[http://fr.wikipedia.org/wiki/Acide_polylactique/ acide polylactique] utilisé dans nos imprimantes 3D. Il fût découvert avec l'[http://www.societechimiquedefrance.fr/produit-du-jour/ acide-lactique.html| mais est produit à l'aide du maïs.

Plus d'informations sur les caractéristiques du PLA pour l'impression 3D : http://www.reprap.org/wiki/PLA avec les fiches techniques disponibles. A noter que les couleurs peuvent également influencées les valeurs requises.

==problèmes d'humidité==

Le PLA absorbe l'humidité. Donc s'il est stocké dans des conditions humides, il se charge d'eau et cela affecte la qualité de l'impression


===Séchage===

Une technique de séchage sous vide est bien décrite là : http://forums.reprap.org/read.php?1,225427,226091#msg-226091

1 ou 2 h à 40°C à 10-15psi

Une boîte pour faire ça est ici ? http://www.thingiverse.com/thing:35710

===Stockage===

Une fois séché, le PLA doit être maintenu dans un milieu protégé.

La solution la plus simple semble être une boîte/dévidoir
