Method for the additive manufacture of shaped bodies

A method for producing shaped bodies (5) from a building material by a construction process comprising

• successively solidifying layers of the building material through the action of electromagnetic radiation in a layer area having a contour specified for a respective layer to produce a layered structure of a shaped body (5),
• wherein together with the shaped body (5), a frame (6) is constructed layer by layer from the building material,
• wherein the frame (6) is constructed in the form of a sleeve defining a longitudinal axis, wherein the frame includes a circumferential frame wall that is extended along the longitudinal axis and surrounds the shaped body at a distance,
• wherein the layer-wise construction of the shaped body takes place on a construction platform, wherein the shaped body and the frame are constructed layer by layer so that the longitudinal axis of the shaped body and the sleeve is oriented transverse to the direction of the layer by layer build-up and a lower outside surface section of the circumferential frame wall faces the construction platform,
• wherein a plurality of pin connections (10) is 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),
• wherein the building material contains photopolymerizable polymer precursor compounds and filler,
• wherein after the construction process, a debinding of the frame (6) and of the shaped body (5) takes place, and
• wherein, in a further step, the shaped body (5) is released from the frame (6) and subsequently is sintered.
