Title (EN) THREE-DIMENSIONAL PRINTING
(FR) IMPRESSION TRIDIMENSIONNELLE
Abstract:
(EN) According to one example, there is provided a method of distributing build material in a 3D printing system. The method comprises moving a build material support positioned below a hopper, the movement to cause build material stored in the hopper to be deposited on the build material support, and moving a recoater to spread build material from the build material support over a build platform to form a layer of build material thereon, and to return any excess build material back to the build material support.
(FR) L'invention concerne, selon un exemple, un procédé de distribution de matériau de construction dans un système d'impression 3D. Le procédé comprend le déplacement d'un support de matériau de construction positionné sous une trémie, le mouvement permettant d'amener un matériau de construction stocké dans la trémie à être déposé sur le support de matériau de construction, et le déplacement d'un dispositif de recouvrement pour étaler le matériau de construction à partir du support de matériau de construction sur une plate-forme de construction afin de former une couche de matériau de construction sur cette dernière, et pour renvoyer tout matériau de construction en excès au support de matériau de construction.
