Patent number: 8741194Abstract: The invention relates to a method for producing a part using a deposition technique, especially a part in the form of a casting mold or a casting core. A layered composite is built up in layers, the individual layers each containing particulate material and binding material as well as optionally, a treatment agent. The layers maintain a predetermined porosity. The binding agent can be hardened especially with a fluid hardening agent. The layer composite is built up in the absence of the hardening agent. Once construction is complete, the layer composite is flooded with the fluid hardening agent using the residual porosity of the predetermined partial areas and in this way, is hardened.Type: GrantFiled: September 25, 2000Date of Patent: June 3, 2014Assignee: Voxeljet AGInventors: Ingo Ederer, Rainer Höchsmann
