Abstract
Disclosed is a method for manufacturing a green piece made of ceramic material by the technique of additive manufacturing according to which layers of a photocurable paste are successively allowed to cure by irradiation according to a pattern defined for each layer, the first layer being formed on a working surface on a working tray, each layer, before curing, being spread by scraping a paste mass provided on the working tray, which is lowered upon each formation of a layer. According to the disclosure, when spreading at least one of the photocurable paste layers, at least one scraping blade in working position, in addition to its scraping motion or so-called pass motion, is allowed to go back and forth in its plane, according to a so-called vibration motion.
