Abstract
The invention relates to a self-hardening material for layerwise construction of three-dimensional components, whereby the material comprises at least one particulate material and a separately applied bonding agent for bonding the particulate material, and has a setting time which is at least several times as long as the application time of a particulate layer.

18. A process comprising the steps of:
-
a. applying at least one particulate material; and b. separately applying a bonding agent for bonding the at least one particulate material; wherein a setting time is at least several times as long as an application time of a layer of the at least one particulate material; wherein the process is a process for layerwise construction of a three-dimensional component. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A process comprising the steps of:
-
applying a first layer of a self-hardening material for printing a three-dimensional component; applying a second layer of a self-hardening material for printing the three-dimensional component, and setting the first layer after applying the second layer; wherein the second layer is applied on top of the first layer while the first layer is not yet hardened, and wherein the first layer and the second layer shrink by the same amount and at the same time;
the first layer and the second layer each include a layer of a particulate material to which a bonding agent is applied separately;wherein the particulate material includes polymethylmethacrylate, polyethylmetracrylate, ABS, PC-ABS, PA, PBT, a metal, glass, or carbon fiber, and the particulate material is a loose material suitable for applying in a layerwise fashion; and
the bonding agent includes a polymerizable monomer and is a printable liquid suitable for applying over the particulate material. - View Dependent Claims (37)
