An object is to achieve both good washing fastness and texture by combining a urethane resin of high fracture elongation with a small quantity of crosslinking agent. As a means for achieving the object, an inkjet ink composition for textile printing is provided that contains a pigment, a water-dispersible resin, a crosslinking agent, and water; wherein, as the water-dispersible resin, a resin of 1200 to 1800% in fracture elongation and 10 to 48 MPa in tensile strength is contained by 1.0 to 3.0 parts by mass relative to 1 part by mass of the pigment, and the crosslinking agent is contained by 0.03 to 0.17 parts by mass relative to 1 part by mass of the water-dispersible resin.

An edible aqueous inkjet ink and a tablet. The edible aqueous inkjet ink contains a relatively large amount of volatile alcohol, which has improved or even excellent transfer durability and reduces ink ejection failure. The tablet includes a portion printed with the edible aqueous inkjet ink. The edible aqueous inkjet ink according to the present embodiment includes food coloring, ethanol, and a surfactant which has a hydrophilic-lipophilic balance value (HLB) in a range of 16 or more and 20 or less. The food coloring may preferably be sodium copper chlorophyllin. The surfactant may preferably be a sucrose fatty acid ester.

Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.
