Abstract
A method of fabricating a three-dimensional article comprises providing a spatially coherent light source (), generating from the light source (), patterns of light based on computed tomographic projections of the three-dimensional article, and projecting the patterns of light into a photoresponsive medium. The projecting is configured to define a three-dimensional dose distribution, thereby locally altering the phase of the photoresponsive medium and creating the article.
