Abstract Three-dimensional printers--known in the industrial world as solid-imaging machines--are already here in nascent form, transforming the way products are designed. Solid imaging also permits three-dimensional copying. At a Los Angeles computer-graphics show last summer, more than 700 people poked their heads into a laser-scanner linked to a solid-imaging machine. Each person was rewarded with a small glimpse at the future: a two-inch-tall, micromillimeter-accurate sculpture of his or her face. Applications that seem exotic today will become routine, as solid imaging grows rapidly cheaper and more versatile. XX
