Method and apparatus for layerwise production of a 3D object
First Claim
1. A system for layerwise production of a tangible object, the system comprising:
- a construction shape arranged to provide a liquid layer of limited height that does not contact the tangible object, 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;
removing means for removing uncured material from the layer outside the intersection pattern;
moving means for moving, relative to one another, the construction shape to a predetermined position relative to the tangible object, such that the moving means moves the liquid layer on the construction shape into contact with the tangible object, for solidifying a predetermined area of a successive such liquid layer;
characterized in thatthe system is arranged to move said construction shape and to operate said solidifying means simultaneously, such that the moving means moves the construction shape to bring the liquid layer into contact with the tangible object while the solidifying means solidifies a predetermined area of such liquid layer.

Abstract
A system and method of layerwise production of a tangible object (5), they system comprising a construction shape (6) to form a liquid layer to be brought in contact with the tangible object; solidifying means (9) for solidifying a predetermined area of a layer (10) of the liquid (3), so as to obtain a solid layer (14) of the tangible object (5), the solid layer thus having a predetermined shape, separating means (18; 19′; 19″) for separating said solid layer from said construction shape; moving means (18) for moving, relative to one another, the construction shape (6) to a predetermined position relative to the tangible object (5), 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.
