1. A method for creating a textured surface on a breast implant, the method comprising:

  • providing a breast implant shell;

    applying a first tacky layer onto the shell;

    using a three-dimensional printing process to deposit a texturing material onto the first tacky layer to form a micrometer-scale pattern for creating an imprint on the first tacky layer;

    curing the first tacky layer to form a first cured, imprinted layer;

    removing the texturing material from the tacky first cured, imprinted layer to obtain a textured surface that facilitates cell ingrowth on the textured surface;

    after removing the texturing material from the first cured, imprinted layer, applying a second tacky layer onto the first cured, imprinted layer;

    depositing, via three-dimensional printing, additional texturing material onto the second tacky layer to form a second micrometer-scale pattern for creating a second imprint on the second tacky layer;

    curing the second tacky layer to form a second cured, imprinted layer; and

    removing the texturing material from the second cured, imprinted layer to obtain a second textured surface that facilitates cell ingrowth on the second cured, imprinted layer.
