Abstract

On décrit une imprimante 3D basée sur l'internet des objets ayant une fonction de commande en boucle fermée, qui comprend un terminal de communication intelligent (1) et une imprimante 3D connectés sans fil l'un à l'autre. L'imprimante 3D comprend un mécanisme de réglage de déplacement, une buse d'impression et une plate-forme de travail (11), le mécanisme de réglage de déplacement étant raccordé par entraînement à la buse d'impression et comprenant deux organes de réglage de déplacement. L'imprimante 3D basée sur l'internet des objets ayant la fonction de commande en boucle fermée permet à un opérateur de régler et commander à distance et en temps réel l'imprimante 3D à travers le terminal de communication intelligent (1) et l'imprimante 3D connectés sans fil. Un capteur de déplacement (7) mesure avec précision la position de la buse d'impression et coopère avec le mécanisme de réglage de déplacement pour former une commande en boucle fermée, ce qui améliore la précision de déplacement de l'imprimante 3D. Un capteur de température (20) surveille en temps réel la température de travail d'un dispositif de chauffage (9) et coopère avec un module régulateur de chauffage (18) pour former une commande en boucle fermée, ce qui améliore la précision de température de l'imprimante 3D.
