    摘要： Disclosed are embodiments of 3D printing compositions that incorporate light scattering and wavelength-shifting metal nanoparticles, and systems and methods of using the 3D printing compositions. In some embodiments, the 3D printing compositions containing metal nanoparticles cure faster upon exposure to UV radiation. In some embodiments, the 3D printing compositions containing metal nanoparticles scatter incoming UV light throughout printed layers of the 3D printing compositions. It is proposed that metal nanoparticles produced by high energy methods possessing smooth spherical morphology and narrow size distributions can be integrated into 3D printing compositions to mitigate the risk of over-curing due to the light-scattering and/or down-shifting effect of the nanoparticles. A method for adding the nanomaterials to the 3D printing compositions in a non-interruptive process is also disclosed.

    摘要： The present invention provides an improved method for curing multi-layer constructs of energy curable (EC) inks and coatings with actinic radiation. In the method, one or more layers of EC inks and/or coatings comprising materials that can crosslink or polymerize when exposured to actinic radiation, e.g., monomers, oligomers or polymers, are applied to a substrate, which EC inks and coatings contain little or no photoinitiators. This is followed by applying one or more layers of non-EC inks and/or coatings, which comprise one or more organic peroxides but no readily polymerizable components, over the top of the layers of energy curable inks and/or coatings; and exposing the layers to actinic radiation.

    摘要： A water-based ink comprises an ink raw material, water, a resin, a desiccant, a defoamer, a hardener, a color fixative, and a dispersant. Based on the total volume of the water-based ink, the ink raw material has an amount of from 10 volume percentage (vol %) to 15 vol %, the water has an amount of from 60 vol % to 67 vol %, the resin has an amount of from 6 vol % to 12 vol %, the desiccant has an amount of from 5 vol % to 10 vol %, the defoamer has an amount of from 3 vol % to 8 vol %, the hardener has an amount of from 4 vol % to 9 vol %, the color fixative has an amount of from 2 vol % to 7 vol %, and the dispersant has an amount of from 3 vol % to 9 vol %. The printing film produced by the water-based ink is suitable for plastic flooring.

The compound is of formula (VI); R1, and R2 are independently selected from an optionally substituted linear or branched alkyl group, alkenyl group, alkoxy group, aryl group and an alkylene aryl group having from 5 to 22 carbon atoms; X1 and X2 are independently selected from —OC(O)—, —CO2— and O; Y1, and Y2 are independently selected from hydrogen, halogen, R1, —OR1; y is independently 0 or 1; and suitably the groups R1X1— and —X2R2 are independently in the ortho or meta position. The compounds are useful in ink compositions, writing implements containing the compound and medical and industrial applications in which temperature sensitive colour change may be required.

    摘要： The present invention relates to silver ink for printing a three dimensional microstructure and a 3D printing method using the same. The present invention provides a method for printing a 3-dimensional silver structure pattern, the method including: a step of providing a nozzle with liquid ink including capped silver nanoparticles and exhibiting Newtonian fluid behavior; a step of forming, at a predetermined point on a substrate, a meniscus of the liquid ink with ink extruded from the nozzle; a step of allowing the ink of the nozzle to be extruded by means of the surface tension of the meniscus while moving the nozzle along a path in a direction perpendicular to the substrate, in a direction parallel to the substrate, or according to a combination of said directions; and a step of forming a silver structure pattern corresponding to the movement path of the nozzle by evaporating a solvent from the extruded ink from the region closer to the substrate. The present invention can provide a 3D printing method based on direct ink printing that is suitable for application to 3D printing electronic technology.
