Patent number: 9636870Abstract: A powder transfer mechanism laminates powder layers containing water-soluble powder as a main component one by one at a modeling portion. An inkjet line head injects a water-based ink that dissolves the powder in an area of an uppermost layer of the powder layers laminated by the powder transfer mechanism, the area corresponding to a cross-sectional shape of a modeled object. Then, a heater heats the powder for each layer of the powder layers. Further, the heater heats the powder after the water-based ink is injected by the inkjet line head or before the water-based ink is injected by the inkjet line head. The present invention can be applied to a modeling apparatus, for example.Type: GrantFiled: May 14, 2009Date of Patent: May 2, 2017Assignee: Sony CorporationInventors: Junichi Kuzusako, Masanobu Yamamoto, Akira Ookubo, Toshihiro Kamewa, Tomohide Koizumi, Kazuma Tamura, Takeshi Matsui

Patent number: 8186415Abstract: A method for manufacturing a mold, including steps of (a) expanding a powder mixture containing a water-soluble inorganic salt powder and a water-soluble organic polymer powder in a plane on a table and then selectively spraying a spray liquid containing at least one selected from a water-miscible organic solvent and water through a nozzle on this powder mixture layer to make a bonding strength among particles of the powder mixture in a sprayed region higher than that among particles of the powder mixture in an unsprayed region, (b) further expanding the powder mixture on the powder mixture layer after spraying and then selectively spraying the spray liquid through the nozzle on this powder mixture layer, (c) repeatedly conducting the step (b) over several times to form a mold shaped by the sprayed regions, and (d) taking out the mold.Type: GrantFiled: April 8, 2011Date of Patent: May 29, 2012Assignee: Tomita Pharmaceutical Co., Ltd.Inventors: Yoji Marutani, Minoru Tomita, Hisaaki Hashimoto, Tomohide Koizumi, Kazuhiko Tamagawa, Akira Ookubo, Nozomu Hashimoto

Publication number: 20110059247Abstract: [Object] To form a modeled object with high accuracy. [Solving Means] A powder transfer mechanism (16) laminates powder layers containing water-soluble powder as a main component one by one at a modeling portion (14). An inkjet line head (17) injects a water-based ink that dissolves the powder in an area of an uppermost layer of the powder layers laminated by the powder transfer mechanism (16), the area corresponding to a cross-sectional shape of a modeled object. Then, a heater (18) heats the powder for each layer of the powder layers. Further, the heater (18) heats the powder after the water-based ink is injected by the inkjet line head (17) or before the water-based ink is injected by the inkjet line head (17). The present invention can be applied to a modeling apparatus, for example.Type: ApplicationFiled: May 14, 2009Publication date: March 10, 2011Applicants: Sony Corporation, Tomita Pharmaceutical Co., Ltd.Inventors: Junichi Kuzusako, Masanobu Yamamoto, Akira Ookubo, Toshihiro Kamewa, Tomohide Koizumi, Kazuma Tamura, Takeshi Matsui
