Patent ID: 7736578

Claim:
A method for the construction of a multi-layered laminated compound formed of particulate matter comprising the steps of: a. placing a layering unit over a working field; b. utilizing data to control movement and operation of the layering unit; c. lifting the layering unit; d. moving the layering unit; e. depositing a layer consisting of solid particulate matter from an elongated dispensing opening in a dispensing device in the layering unit with a predetermined layer thickness and a predetermined pattern on the working field; f. delivering a hardener selectively to the solid particulate matter to join it to any previously deposited particulate matter; and g. repeating steps (b-f) until the multi-layered laminated compound is complete; whereby the multi-layered laminated compound on the working field is formed freestanding and without the use of an outer edge enclosure device for a respective top layer to be deposited, that the dispensing device is moved on a frame which can gradually be adjusted vertically upwards by its layer thickness before the depositing of each respective top layer, and whereby the deposited top layer is hardened along an edge area of at least the front edge in the direction of movement of the dispensing device by the administering of a laser beam or by the application of a binding agent, so that a hardened boxing of the laminated compound is formed from the particulate matter, at least along its front end in the direction of movement of the dispensing device.
