  • Method and device for layered buildup of a shaped element
    Patent number: 9457514
    Abstract: Since concrete materials do not cure quick enough when prototyping methods are used, so that a lower layer (2a) is already completely cured when the next layer (2b) is applied, a support material (4) is applied about the formed element (100) that is being built up in order to compensate for the lack of pressure resistance of the lower layer (2a), wherein the support material preferably has the same specific weight as the material (3) of the formed element (100). Thus, 3D-printing as well as selective curing are facilitated as build up methods.
