  • Patent number: 11173705
    Abstract: A printing device prints an object on a medium by inkjet printing. The printing device includes: a glossy ink head that discharges ink droplets of a glossy ink having a glossy color; and a main scan driver that prompts the glossy ink head to perform main scans in which the glossy ink head discharges the ink droplets while moving in a predetermined main scanning direction. The glossy ink contains a glossy pigment. In the main scans, the glossy ink head discharges the ink droplets plural times while moving in the main scanning direction to form ink dots at positions on the medium aligned in the main scanning direction. The ink droplets discharged from the glossy ink head each have a volume constituting a size that allows for contact on the medium between any ones of dots formed in each one of the main scans.

  • Patent number: 11173703
    Abstract: A method for forming a three-dimensional object by extruding ink droplets from ink-jet heads includes forming an inner build region of the object. A colored region is formed outside of the inner build region so as to color the object. A support region is formed outside of the colored region so as to support the object while the object is being formed. An intermediate region is formed between the inner build region and the colored region. The intermediate region is formed in such a manner that affinity between the intermediate region and the inner build region and affinity between the intermediate region and the colored region are higher than affinity between the colored region and the support region.

  • Patent number: 10807306
    Abstract: A three-dimensional-object forming apparatus includes a platform that includes a support surface for a three-dimensional object. An extrusion head is movable relative to the platform in main scanning and sub-scanning directions to extrude a build material to the support surface. A measurer measures an environment temperature around the object on the support surface. A controller includes a storage and a processing unit. The storage stores data of a forming condition in correlation with the environment temperature. The forming condition specifies a condition for a forming operation to form the object. The processing unit causes the platform and the extrusion head to perform the forming operation, updates the forming condition during the forming operation based on the measured environment temperature and the data stored in the storage, and causes the platform and the extrusion head to perform the forming operation under the updated forming condition.
