Abstract
(EN)
A production apparatus (100) for three-dimensional moldings produces three-dimensional moldings in a prescribed molding space comprising multiple unit spaces. The production apparatus (100) three-dimensional moldings is provided with a beam irradiation unit (40) and a control device (20). The beam irradiation unit (40) irradiates a beam (L32) on a molding material. The control device (20) controls the beam irradiation unit (40). The beam irradiation unit (40) is capable of guiding beams (L32) with differing intensities to at least two unit spaces among the multiple unit spaces. The control device (20) comprises an irradiation control unit (21) for controlling the beam irradiation unit (40) so as to irradiate beams (L32), which have intensity distributions prepared on the basis of flow information, on the molding material. When at least two unit spaces adjoin each other, the flow information comprises information representing flow of the molding material between the at least two unit spaces.

La présente invention concerne un appareil de production (100) pour moulages tridimensionnels qui produit des moulages tridimensionnels dans un espace de moulage prescrit comprenant une pluralité d'espaces unitaires. L'appareil de production (100) pour moulages tridimensionnels est pourvu d'une unité de rayonnement par faisceau (40) et d'un dispositif de commande (20). L'unité de rayonnement par faisceau (40) expose un matériau de moulage à un faisceau (L32). Le dispositif de commande (20) commande l'unité de rayonnement par faisceau (40). L'unité de rayonnement par faisceau (40) peut guider des faisceaux (L32) présentant des intensités différentes vers au moins deux espaces unitaires parmi la pluralité d'espaces unitaires. Le dispositif de commande (20) comprend une unité de commande de rayonnement (21) permettant de commander l'unité de rayonnement par faisceau (40) de façon à faire rayonner des faisceaux (L32), qui ont des distributions d'intensité préparées sur la base d'informations de flux, sur le matériau de moulage. Lorsqu'au moins deux espaces unitaires se rejoignent, les informations de flux comprennent des informations représentant un flux du matériau de moulage entre au moins les deux espaces unitaires.
