the site explains:
TAIZ Design’s patent pending Life Cast Systems™ process captures the subtle nuances of the face and its expression in 3D form with unprecedented comfort, speed and accuracy. The facial imprint is created in 20 seconds, recording micro detail of the skin’s pores, muscle tone and tiny wrinkles, as well as the features inside the mouth when open.
Life Cast Systems eliminates the mess, the 45-minute sitting time and the uncomfortable weight of traditional life-casting techniques. The process captures gestures held for only a moment, in essence creating a 3D snapshot. Elegantly designed for a variety of settings, the service and system can cast up to 12 people per hour.
