Title (EN) THREE DIMENSIONAL PRINTING SYSTEM WITH EFFICIENT POWDER HANDLING SYSTEM
(FR) SYSTÈME D'IMPRESSION EN TROIS DIMENSIONS DOTÉ D'UN SYSTÈME DE MANIPULATION DE POUDRE EFFICACE
Abstract:
(EN) A three dimensional (3D) printing system includes a print engine, a first powder handling module, a sieve, a second powder handling module, and a controller. The controller operates the print engine to fabricate 3D articles of manufacture. The controller operates the first powder handling module to transfer excess powder from the print engine to the first powder handling module and to receive new powder. The first powder handling module dispenses powder to the sieve. The controller operates the second handling module to transfer powder from the sieve to the second powder handling module. The second powder handling module provides powder to the print engine.
(FR) La présente invention concerne un système d'impression en trois dimensions (3D) comprenant un moteur d'impression, un premier module de manipulation de poudre, un tamis, un second module de manipulation de poudre et un dispositif de commande. Le dispositif de commande actionne le moteur d'impression pour fabriquer des articles en 3D. Le dispositif de commande actionne le premier module de manipulation de poudre pour transférer la poudre en excès du moteur d'impression au premier module de manipulation de poudre et pour recevoir une nouvelle poudre. Le premier module de manipulation de poudre distribue de la poudre au tamis. Le dispositif de commande actionne le second module de manipulation pour transférer la poudre du tamis au second module de manipulation de poudre. Le second module de manipulation de poudre fournit de la poudre au moteur d'impression.
