Abstract

Pour délianter et fritter des parties crues d'impression 3D, un liant peut être projeté en couches successives d'une matière première en poudre frittable de façon à construire une forme 3D d'une partie crue 3D souhaitée, des supports de frittage associés et une plate-forme de rétraction associée. Un matériau anti-adhésif peut être déposé de manière à agir entre les parties crues 3D et les supports de frittage. Un matériau de réservation peut être déposé sur une poudre liée de façon à obtenir des formes de couche 2D du matériau de réservation. La matière première en poudre frittable est rechargée et mise de niveau autour du matériau de réservation. Lors d'un déliantage, des cavités internes correspondant aux formes 3D du matériau de réservation sont formées.
