Method and device for layered buildup of a shaped element

摘要

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.

主权项

1. A method for layered buildup, which comprises:
building up layers of a shaped element (100) from liquid or pasty curing material in a container (1), wherein the next layer (2b) is applied before at least the layer (2a) thereunder is cured, characterized in that
a strand (13) made from an element material (3) is simultaneously placed adjacent to a strand (14) made from a support material (4) for forming defining surfaces (101) of the shaped element, so that a subsequent additional deformation of the outside of the strand made from element material cannot occur anymore; andthe element material (3) and the support material (4) are applied in layer thicknesses (17) of more than 2 mm.
