Method and device for producing a three-dimensional shaped object by means of layer-by-layer material application
11565461 · 2023-01-31 · ·

The invention relates to a method for producing a three-dimensional shaped object without height limitation by means of layer-by-layer material application, wherein geometric data for the shaped object, a substrate part having a base surface for holding the shaped object, flowable first and second material, and a transfer body are provided. Material portions of the flowable first material are applied to the base surface and/or to a solidified material layer of the three-dimensional shaped object located on the base surface in accordance with the geometric data in order to produce a material layer of the three-dimensional shaped object. The material layer consisting of the first material is solidified. A surface region of the transfer body is coated with a layer of the second material, and said layer is brought into contact with the surface of the topmost solidified material layer of the three-dimensional shaped object facing away from the base surface in such a way that the flowable second material is transferred from the transfer body to the surface of the topmost solidified material layer of the three-dimensional shaped object and forms the further material layer on the surface of the topmost solidified material layer of the three-dimensional shaped object, the structure of which further layer corresponds to the structure of the topmost solidified material layer of the three-dimensional shaped object. The further material layer is likewise solidified.
