Title
(EN) THREE-DIMENSIONAL MODELING DEVICE
(FR) DISPOSITIF DE MODÉLISATION EN TROIS DIMENSIONS
(JA) 三次元造形装置
Abstract
(EN)
This three-dimensional modeling device is provided with: a table that supports a powder material and a model created from the powder material; a processing section that is disposed so as to face the table and that obtains the model by processing the powder material; and a rotation unit for causing the table to rotate with respect to the processing section about a rotational axis. The processing section has multiple processing units disposed about the rotational axis. The processing units supply the powder material to the table, preheat the supplied powder material, and emit an energy beam to the preheated powder material.
(FR)
L'invention concerne un dispositif de modélisation en trois dimensions qui est pourvu de : une table qui supporte un matériau en poudre et un modèle créé à partir du matériau en poudre ; une section de traitement qui est disposée de façon à faire face à la table et qui obtient le modèle en traitant le matériau en poudre ; et une unité de rotation pour amener la table à tourner par rapport à la section de traitement autour d'un axe de rotation. La section de traitement comporte de multiples unités de traitement disposées autour de l'axe de rotation. Les unités de traitement fournissent le matériau en poudre à la table, préchauffent le matériau en poudre fourni et émettent un faisceau d'énergie vers le matériau en poudre préchauffé.
