Généralités

L'impression 3D est une technique additive de fabrication numérique. Il existent plusieurs technologies :

Impression 3D par fil fondu (FDM)

Le principe d’impression 3D FDM repose sur le principe suivant : un filament plastique est fondu et déposé sur une plateforme d’impression, formant l’objet couche après couche.
