The invention provides a micro-stereo lithography solidification thick-film layer-by-layer automatic molding method and a corresponding apparatus, belonging to the micro-stereo (quick) lithography molding and processing field. The apparatus comprises two precise linear movement platforms which can be conveniently controlled by a computer in an integrated manner, an integrated double-opening resintrough, a molding trough, a scraper and a position controller of the scraper. A sliding block of a vertical precise linear movement platform is fixedly connected with an upper extrusion sliding plug and a sliding object stage through a linkage; a high linearity scraper is arranged on a sliding-block beam of a horizontal precise linear movement platform; the integrated double-opening resin trough and the molding trough are respectively a two-opening liquid-resin trough provided with a communicated inner part and a comparative independent molding trough provided with a round opening; the scraper is provided with a linear knife-edge with better hydrophobic property and high linearity and the left-right end position controller of the scraper is arranged an integrated box-shaped platform; all the parts are arranged on a base platform and all the drive and control circuits are connected with a control box controlled by a computer. The invention has compact structure; a liquid-resin thick-film with high precision and even-thickness can be obtained by the invention; automatically adding the liquid-resin and molding the thick film layer by layer can be realized based on the computer control technique; a connection with the 'micro-stereo lithography' is also realized; the method and the apparatus have the advantages of high automation, integration and better operability.
