Abstract

The invention relates to a method and a device for producing 3D shaped parts (300), comprising a plurality of construction field tools (500), which are arranged in a movable manner, and at least one layer unit (800) which is arranged in a movable manner.

First claim

What is claimed is:

1 . A device for manufacturing 3D molded parts, characterized in that it comprises at least one or more construction field tools, arranged in a movable manner, and at least one layering unit, also arranged in a movable manner.

2 . The device according to claim 1 , characterized in that the layering unit(s) are movable in the direction of Z or/and X.

3 . The device of claim 1 , wherein the construction field tool(s) are movable in the direction of X or/and Y.

4 . The device of claim 1 , wherein the one or more construction field tools includes a plurality of construction field tools arranged in series and connected to each other.

5 . The device of claim 1 , wherein the one or more construction field tools and the at least one layering unit are controllable in a directed, coordinated manner.

6 . The device of claim 1 , wherein the one or more construction field tools substantially have the dimensions of the 3D molded part to be manufactured.

7 . The device of claim 1 , wherein the one or more construction field tools includes a plurality of construction field tools connected to each other by one or more chains, one or more toothed belts, one or more racks, one or more cable pulls, or one or more hydraulic means, and the plurality of construction field tools are thereby movable or/and can thereby be synchronized.

8 . The device of claim 1 , wherein the device is configured to work in a synchronized manner.

9 . The device of claim 1 , wherein the device comprises means for process steps after construction of the 3D molded parts or/and the device comprises means for automated removal of the 3D molded parts.

10 . A method for manufacturing 3D molded parts, wherein 3D molded parts are produced using known means of 3D printing, comprising a step of:
producing each of the 3D molded parts in a separate construction field tool by means of a layering unit.

11 . The method of claim 10 , wherein the construction field tools are moved in a coordinated manner.

12 . The device of claim 1 , wherein
the one or more construction field tools includes a plurality of construction field tools arranged in series and connected to each other; the one or more construction field tools and the at least one layering unit are controllable in a directed, coordinated manner.

13 . The device of claim 12 , wherein the one or more construction field tools substantially have the dimensions of the 3D molded part to be manufactured.

14 . The device of claim 13 , wherein
the construction field tool(s) are movable in the X and/or Y directions; and the layering unit(s) are movable in the X and/or Z directions.

15 . The device of claim 14 , wherein the device is configured to work in a synchronized manner.

16 . The device of claim 12 , wherein the plurality of construction field tools are connected to each other by one or more chains, one or more toothed belts, one or more racks, one or more cable pulls, or one or more hydraulic means, and the plurality of construction field tools are thereby movable or/and can thereby be synchronized.

17 . The device of claim 14 , wherein the plurality of construction field tools are connected to each other by one or more chains, one or more toothed belts, one or more racks, one or more cable pulls, or one or more hydraulic means, and the plurality of construction field tools are thereby movable or/and can thereby be synchronized.

18 . The device of claim 14 , wherein the layering unit includes a printhead between two coaters.

19 . The device of claim 18 , wherein the plurality of construction field tools are connected to each other by one or more chains, one or more toothed belts, or one or more cable pulls.

20 . The device of claim 18 , wherein the plurality of construction field tools are connected to each other by one or more racks or one or more hydraulic means.
