Abstract

A three-dimensional laminated product forming apparatus and method for forming a three-dimensional laminated product from a photo-curable liquid by progressively superposing solid laminae one on top of another by photo-curing a surface layer of the photo-curable liquid and converting it to a solid lamina. A product table is provided on which a three-dimensional solid product is built up in progressive steps and which is incrementally advanced into the photo-curable liquid by a specified depth each step. A liquid surface leveling device works as a capillary to draw up a photo-curable liquid by capillary action while it is in contact with the surface of the photo-curable liquid contained in the container. The device is moved over the surface of the photo-curable liquid to apply the collected photo-curable liquid over a three-dimensional laminated product being partly built up on a product table to form a uniform thickness of a surface layer of the photo-curable liquid with a surface leveled and smoothed over the three-dimensional laminated product being partly built up. An irradiating head forms a beam spot of reactive stimulation on the surface to cure the surface layer and convert it to a solid lamina on the three-dimensional laminated product being partly built up as the three-dimensional laminated product.
