The additive manufacturing device includes a container for providing at least one mould material, a build platform having a build surface for holding and/or supporting at least one mould being or having been manufactured by an additive manufacturing process, a source for providing energy to selectively activate and subsequently solidify the at least one mould material in or from the container to enable additive manufacturing of the mould, and an electronic controller adapted to selectively control the source to manufacture the mould as a one-piece sacrificial mould according to a predetermined design producing a one-piece additively manufactured mould.

Abstract: An additive manufacturing apparatus having a container for holding a radiation-curable liquid, and a build platform having a build surface for holding a product being manufactured during a manufacturing process. The build platform is movable relative to the container in a predetermined direction. The apparatus also includes a radiation source for providing hardening radiation to selectively solidify radiation-curable liquid in the container by exposure to form the product. The container includes an interior floor having a flexible floor part maintainable in a planar configuration in which the flexible floor part is planar. A radiation-curable liquid in contact with the interior floor is confined by a container wall having a flexible wall section arranged to move intactly with the flexible floor part.
