The invention relates to an additive manufacturing device (41) for the layered production of three-dimensional objects (26,46) from a polymerizable liquid (43). The device (41) comprises a trough (22,42) with a bottom (48) for receiving the liquid (43), a support platform (45), on which the object (46) is built up and which is height-adjustable relative to the trough (42), a structural element (51) having a first and a second side (55), on which the liquid (43) polymerizes on the first side (53) to form an object layer (50), and a radiation source (44) which irradiates the second side (55) of the beam-permeable structural element (31,51). The structural element (51) is disposed above the upper support platform (45). La invención se refiere a un dispositivo de fabricación aditiva (41) para la producción en capas de objetos tridimensionales (26,46) a partir de un líquido polimerizable (43). El dispositivo (41) comprende un acabado (22,42) con una parte inferior (48) para recibir el líquido (43), una plataforma portadora (45) en la que se construye el objeto (46) y que es de altura ajustable en relación al acabado (42), un elemento estructural (51) que tiene un primer y segundo lado (55) en el que el líquido (43) se polimeriza en el primer lado (53) para formar una capa del objeto (50) y una fuente de radiación (44) que irradia el segundo lado (55) del elemento estructural de viga permeable (31,51). El elemento estructural (51) es colocado sobre la parte superior de la plataforma de soporte (45).
