Abstract
A method or procedure for the construction of a laminated compound or mould made up of a number of layers of particle material on top of each other, which are hardened and joined to each other in predetermined onsite areas, which can differ from each other depending on position and expansion, so that from the predetermined hardened areas of the laminated compound at least one mould is formed. The layers are deposited individually one after another in predetermined layer thickness by the dispensing of particle material from a dispensing device during its movement above a working field and according to computer data in predetermined areas.
Claims19
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.

- f. delivering a hardening means selectively to the solid particular 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 supported by pillars of a base frame, the dispensing device can be gradually adjusted in a vertical direction and has an access opening over the working field for the measured dispensing of the particle material onto the working field, the access opening can be moved horizontally on the dispensing device, wherein the access opening has an elongated dispensing opening which is open at the bottom, which extends horizontally straight and vertical to the direction of movement of the dispensing device, and which can be systematically switched on and off for the systematic dispensing of the particulate matter, 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.

- 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 of 100 to 500 μm and a predetermined pattern on the working field, whereby the dispensing device which has a funnel-shaped dispensing duct for the solid particular matter to be deposited, is set into motion from a position where its dispensing opening is at a distance in front of a front edge of the previous layer in the direction of movement of the dispensing device, and is switched on when its dispensing opening reaches the area above the front edge of the previous layer and whereby the dispensing device is moved over a back edge of the previous layer in the direction of the movement, and switched off when its dispensing opening reaches the area above the back edge of the previous layer;
- f. smoothing and/or compressing the top layer behind the dispensing opening during the movement of the dispensing device in the direction of movement;
- g. delivering a hardener selectively to the particulate matter to join it to any previously deposited particulate matter;
