The three dimensional configuration of an article is generated from a plurality of sheets of polymer material having a base resin constituent, a reactive diluent constituent and a reaction modifying constituent which effects a latent change in chemical reactivity of the polymer material in an area of each sheet imaged with actinic radiation in the configuration of an incremental heighth of the article, successive sheets are exposed to actinic radiation corresponding to the configuration of successive incremental planar heighths of the article and are stacked in a matrix. The imaged areas of all sheets are thereafter simultaneously cured with heat or aging, the configuration of the article is separated from the remainder of the matrix by altering the dimensional stability of the uncured polymer material. The sheets may be initially positioned on a carrier web for transport through an apparatus for constructing the shape of an article. The apparatus includes an imaging station wherein successive sheets are exposed to actinic radiation and a stacking station wherein exposed sheets are stripped from the carrier web and placed in a stack to form the matrix.

A system for forming an article includes an apparatus for stacking successive sheets of a polymer mixture and selectively irradiating each sheet with an electron beam deflected to trace the configuraiton of an incremental heighth of the article. The polymer mixture may include a polymer resin mixed with a reactive diluent and, if required, an initiator. The stacked sheets form a matrix which supports the article as it is being shaped. After integration of all incremental heighths of the article, heat or chemical dissolution is employed to remove the matrix. The sheets may be a laminate of a stratum bonded to a substratum. The substratum is easily compressed under heat to reference the level of the upper surface of the sheet irrespective of thickness variations of the sheet. To compensate for beam intensity absorption, the substratum is formulated with increased sensitivity. Successive sheets are heated while being transported to a platen which is positioned beneath an electron gun.
