  • Patent number: 5744291
    Abstract: This disclosure concerns with a method of producing 3D print materials and the structure thereof. In the preferred embodiment of the present invention, the 3D print material consists of a lenticular screen, an image forming layer and an anti-halation layer coated on the image forming layer opposite from the lenticular screen. When the thickness of the lenticular screen reaches a certain amount, it renders the coating of an image forming layer onto the lenticular screen too difficult or impractical. With such a thickness, it is advantageous to coat the image forming layer and the anti-halation layer on a clear polymer base, and then securely attach the coated polymer base to a bare lenticular screen with the aid of a bonding layer. Similarly, a parallax barrier plate can be used in lieu of a lenticular screen for producing 3D print materials.
