METHOD FOR LAYERED CONSTRUCTION OF MOLDED ARTICLE MADE FROM HIGHLY VISCOUS PHOTOPOLYMERIZABLE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for effectively refilling an empty space in material distribution of exposed area in a tank with a photopolymerizable material.;SOLUTION: A slender mixing element moves essentially across its longitudinal direction in relation to a tank bottom, covering the tank bottom in the exposed area under a manufacturing platform to that the photopolymerizable material may be refilled in the exposed area under the manufacturing platform. The slender mixing element has dimensions and is driven along at least a portion of tank length in a positional mode where the upper end of mixing element remains lower than the material level of the photopolymerizable material outside the exposed area in the tank.;COPYRIGHT: (C)2013,JPO&INPIT
