摘要： A stereolithography device having a trough (2) for accommodating free-flowing, photopolymerizable material, a construction platform (4) suspended above the trough bottom on a lifting unit (6), and having a heating unit for heating the photopolymerizable material in the trough. The heating unit has a transparent, electrically conductive layer (33), which covers the entire area of at least the exposure region above the trough bottom, and which is provided outside the exposure region on opposing sides of the layer with electrical contacts (20) extended over the opposing sides, which are connected to a controlled electrical supplier to enable heating of the entire area of photopolymerizable material above the trough bottom in the exposure region by current flow through the layer.

摘要： The present invention relates to a method for producing shaped bodies (5) from a building material, in which a layered structure of a shaped body (5) takes place by successively solidifying layers of the building material by exposure to electromagnetic radiation in a layer area having a contour specified for the respective layer. The method provides that together with the shaped body (5), a sleeve-like frame (6) surrounding the shaped body at a distance is constructed layer by layer from the building material, and that in addition, a plurality of pin-like connections (10) are constructed integral with the frame (6) and the shaped body (5), which are distributed around the shaped body (5) and which connect the shaped body (5) with the frame (6).
