A method for manufacturing a sintered product from a three-dimensional object includes: A preparation step S11, a multilayer made of an ink containing inorganic particles and an organic material is formed to prepare a three-dimensional object. A degreasing step S12 includes: a first degreasing step of heating the three-dimensional object under an inert gas atmosphere at a first average degreasing temperature (T1) for a first heating time to degrease the organic material; and a second degreasing step of heating the three-dimensional object degreased in the first degreasing step, under an inert gas atmosphere at a second average degreasing temperature (T2) higher than T1 for a second heating time to degrease the organic material. A sintering step S13, the three-dimensional object degreased in the second degreasing step is sintered at an average sintering temperature higher than T2 to obtain a sintered product.

Method for manufacturing sintered product from three-dimensional object, and 3D shaping inkjet ink

Provided are a maintenance liquid and a maintenance method that can solve an ejection problem of a UV curable inkjet printer. The maintenance liquid includes: a first ingredient in which a water-soluble compound is soluble and a cured matter of a UV curable ink is insoluble. The maintenance method includes: a first cleaning process at which a water-soluble compound that adheres to an inkjet head included in the UV curable inkjet printer is dissolved by a first maintenance liquid including the first ingredient in which the water-soluble compound is soluble and a cured matter of a UV curable ink is insoluble, and a second cleaning process at which the inkjet head is cleaned by a second maintenance liquid including a second ingredient in which the water-soluble compound is insoluble and the cured matter of the UV curable ink is soluble.

Maintenance liquid for solving ejection problem of UV curable inkjet printer

The photocurable inkjet ink contains: a radical polymerizable compound; a photoinitiator; and a thixotropic agent, and has a first viscosity of 1,000 mPa·s or less as measured at a shear rate of 10,000 s, and a second viscosity of 10,000 mPa·s or more as measured at a shear rate set to 10safter a shear force is continuously applied at the shear rate of 10,000 sfor 30 seconds.

Photocurable inkjet ink and method for manufacturing three-dimensional object

To provide an inkjet printing apparatus that improves the smoothness of the ink layer surface and improves the image quality. Provided is an inkjet printing apparatus that prints with a UV curable ink, the inkjet printing apparatus including: an ejection unit configured to eject the UV curable ink onto the surface of a print medium; and a control unit configured to control the ejection of the UV curable ink from the ejection unit, the UV curable ink containing a thixotropy-imparting agent, and the control unit setting the viscosity of the UV curable ink to 1 mPa&#xb7;s to 20 mPa&#xb7;s at the time of ejection and to at least 80 mPa&#xb7;s within five seconds of landing on the print medium.

Inkjet printing apparatus and inkjet printing method

Generation of cockling is suppressed to enable superior image quality printing. An inkjet printing device is provided with a head discharging ultraviolet curing ink onto a medium, pinning irradiation sections irradiating the ultraviolet curing ink on the medium with light, and a curing irradiation section arranged on a downstream side of the pinning irradiation sections in a conveying direction of the medium, and radiating light with a shorter wavelength than the pinning irradiation sections.
