3D PRINTING METHOD FOR PRODUCING CONCRETE-CONTAINING SEGMENTS OF A 3D OBJECT

3D PRINTING METHOD FOR PRODUCING CONCRETE-CONTAINING SEGMENTS OF A 3D OBJECT

The present invention relates to a three-dimensional (3D) printing process for the (layer-by-layer) production of at least one at least three-layer concrete-comprising segment (subregion) of a three-dimensional (3D) object based on concrete. In the process, a first concrete layer is firstly produced...

description The present invention relates to a three-dimensional (3D) printing process for the (layer-by-layer) production of at least one at least three-layer concrete-comprising segment (subregion) of a three-dimensional (3D) object based on concrete. In the process, a first concrete layer is firstly produced by extrusion of fresh concrete. Subsequently, a first adhesive layer is applied on top of the upward-facing side of the first concrete layer, after which a second concrete layer is applied to the upward-facing side of the first adhesive layer. Further adhesive and concrete layers can optionally be applied in succession, with the corresponding concrete layers and adhesive layers in the respective segment being arranged on top of one another in alternating order and the uppermost layer and the lowermost layer of the respective concrete-comprising segment being in each case formed by a concrete layer. The present invention further provides an at least three-layer concrete-comprising segment of a 3D object as such, which is produced by the process of the invention. The invention further provides for the use of at least one at least three-layer concrete-comprising segment as such for producing a 3D object or for incorporation into a 3D object. The present invention further provides a three-dimensional (3D) object as such, comprising at least one at least three-layer concrete-comprising segment which is able to be produced by the process of the invention.
