Abstract
A variety of thermochromic build materials are disclosed for use in color-controlled three-dimensional printing. By providing materials that exhibit a final color dependent upon heat applied during a melt or extrusion process, objects can be fabricated having a user-controlled color that varies from object to object, or within a single object.
