Abstract
In one aspect, methods of printing a 3D article are described herein. In some embodiments, a method of printing a 3D article comprises selectively depositing a first portion of build material in a fluid state onto a substrate to form a first region of build material; selectively depositing a first portion of support material in a fluid state to form a first region of support material; and selectively depositing a second portion of build material in a fluid state to form a second region of build material, wherein the first region of support material is disposed between the first region of build material and the second region of build material in a z-direction of the article. In some cases, the first region of support material forms a grayscale pattern and/or a CMY color pattern in combination with the first region of build material and/or the second region of build material.
