Method and apparatus for layerwise production of a 3d object

Abstract

A system and method of layerwise production of a tangible object (), they system comprising a construction shape () to form a liquid layer to be brought in contact with the tangible object; solidifying means () for solidifying a predetermined area of a layer () of the liquid (), so as to obtain a solid layer () of the tangible object (), the solid layer thus having a predetermined shape, separating means (″) for separating said solid layer from said construction shape; moving means () for moving, relative to one another, the construction shape () to a predetermined position relative to the tangible object (), for carrying out a successive such method cycle for solidifying a predetermined area of a successive such liquid layer; the system is arranged to provide a limited volume of liquid adhered to the construction shape to form a liquid layer of limited height that does not contact the tangible object; wherein said moving of said construction shape and said solidifying of said predetermined area are carried out to take place simultaneously.
