Claims20
A color shift material for three-dimensional printing comprising:
- a color shift pigment having a core-shell structure, wherein the core comprises a silicon oxide and the shell comprises a metal oxide, wherein the color shift pigment has an average diameter of from about 1 to about 50 μm, and
- a polymeric component selected from the group consisting of acrylonitrile butadiene styrene (ABS), poly-lactic acid (PLA), nylon, polyethylene terephthalate (PET), polyvinyl alcohol (PVA), high impact polystyrene (HIPS), laywood, and mixtures thereof, wherein the color shift pigment is dispersed within and chemically bonded to the polymeric component and further wherein the polymeric component is presented in the amount of from about 50 percent to about 99 percent by weight of the total weight of the color shift material.
A three-dimensional product comprising a color shift material that comprises:
- a color shift pigment having a core-shell structure, wherein the core comprises a silicon oxide and the shell comprises a metal oxide, wherein the color shift pigment has an average diameter of from about 1 to about 50 μm, and
- a polymeric component selected from the group consisting of acrylonitrile butadiene styrene (ABS), poly-lactic acid (PLA), nylon, polyethylene terephthalate (PET), polyvinyl alcohol (PVA), high impact polystyrene (HIPS), laywood, and mixtures thereof, wherein the color shift pigment is dispersed within and chemically bonded to the polymeric component and further wherein the polymeric component is presented in the amount of from about 50 percent to about 99 percent by weight of the total weight of the color shift material.
A color shift material for three-dimensional printing in the form of a filament comprising:
- a color shift pigment having a core-shell structure, wherein the core comprises a silicon oxide and the shell comprises a metal oxide, wherein the color shift pigment has an average diameter of from about 1 to about 50 μm, and
- a polymeric component selected from the group consisting of acrylonitrile butadiene styrene (ABS), poly-lactic acid (PLA), nylon, polyethylene terephthalate (PET), polyvinyl alcohol (PVA), high impact polystyrene (HIPS), laywood, and mixtures thereof, wherein the color shift pigment is heated during an extruding step to form the filament such that the color shift pigment is dispersed within and chemically bonded to the polymeric component and further wherein the polymeric component is presented in the amount of from about 50 percent to about 99 percent by weight of the total weight of the color shift material
- wherein the color shift pigment and the polymeric component are extruded with heat at the same time thereby producing a chemically bound pigment-polymeric component.
