Abstract: Objects of various designs are built more appropriately. A building apparatus for building a three-dimensional object includes an inkjet head serving as a head for light-reflective material for ejecting black ink that is a light-reflective material and an inkjet head serving as a head for light-absorbent material for ejecting white ink that is a light-absorbent material. The object has a light-shielding region formed of black ink to block visible light and a non-light shielding region different from the light-shielding region and at least partially formed of white ink. The light-shielding region is formed at a position overlapping at least a part of the non-light shielding region. At least a part of the non-light shielding region overlapping the light-shielding region is a region having a thickness that allows visible light to pass through without the light-shielding region.

Abstract: Provided are a a non-transitory computer readable medium stored with a printing control program, a printing control device, and a printing control method that may reduce a length of time after a printing job is commenced and before another printing job starts to be executed in an inkjet printer. A printer control device includes a printing controller that prompts a 3D printer to perform a printing operation, and an interrupt time storing unit that stores an interrupt time of a printing job executed by the 3D printer when the printing job is interrupted by the printing controller. The printing controller restarts the printing job at the interrupt time stored by the interrupt time storing unit (S232). The printing controller prompts the 3D printer to execute another printing job after the printing job is interrupted and before the printing job interrupted is restarted.
