Abstract
Three dimensional objects are formed by scanning a liquid thermosensitive resin with a laser beam causing imagewise heating of the resin. Because thermosensitive compositions do not obey the law of linear superposition, the problem of stray exposure is eliminated allowing the thermal polymerization of any point within the volume of the liquid without affecting adjacent points.
