Title
(EN) SPIN CLEANING METHOD AND APPARATUS FOR ADDITIVE MANUFACTURING
(FR) MÉTHODE DE NETTOYAGE ROTATIF ET APPAREIL DE FABRICATION ADDITIVE
Abstract
(EN)
A method of separating excess resin from at least one object includes: (a) stereolithographically producing at least one object, each object having at least one retention feature (32) formed thereon, each object carrying excess resin on a surface thereof; then (b) mounting each object on at least one transfer frame (21), each transfer frame having at least one retention member (22) that mates with the retention feature; (c) connecting each transfer frame to a rotor with the at least one object carried thereon; (d) centrifugally separating excess resin from each object by spinning the rotor with each transfer frame connected thereto while the at least one object remains connected to each transfer frame by the retention feature; then (e) removing each transfer frame from the rotor, with excess resin separated from each at least one object thereon.
(FR)
Une méthode de séparation de résine en excès d'au moins un objet comprend : (a) la production par stéréolithographie d'au moins un objet, chaque objet ayant au moins une caractéristique de retenue (32) formée sur celui-ci, chaque objet portant une résine en excès sur une surface de celui-ci ; puis (b) le montage de chaque objet sur au moins un cadre de transfert (21), chaque cadre de transfert ayant au moins un élément de retenue (22) qui s'accouple avec la caractéristique de retenue ; (c) la connexion de chaque cadre de transfert à un rotor avec le ou les objets portés par celui-ci ; (d) la séparation par centrifugation de la résine en excès de chaque objet par rotation du rotor avec chaque cadre de transfert relié à celui-ci tandis que le ou les objets restent connectés à chaque cadre de transfert par la caractéristique de retenue ; puis (e) le retrait de chaque cadre de transfert du rotor, avec une résine en excès séparée de chaque objet sur celui-ci.
