Abstract

A device for generative manufacturing of a component, in particular for layered generative manufacturing of a component which is printed on a base plate. The base plate forms a connecting surface for applying and compacting powder in order to manufacture the component, and includes a plurality of sheets, the sheets being formed and arranged next to one other such that the connecting surface of the base plate is formed by lateral surfaces of the sheets.

First claim

What is claimed is:

1. A device for generative manufacture of parts, the device comprising:
a base plate which forms a connecting surface for applying and compacting powder in order to manufacture the component, the base plate comprising a plurality of sheets,
the sheets being formed and arranged next to one another such that the connecting surface of the base plate is formed by lateral surfaces of the sheets.

2. The device of claim 1 , wherein the device is configured to generate a defined tension force between the sheets, the tension force allowing individual sheets to yield while the powder is applied to and compacted on the connecting surface.

3. The device of claim 2 , wherein the device has a screw connection which is configured to generate the defined tension force.

4. The device of claim 1 , wherein the device comprises a hold-down configured to prevent individual sheets from yielding while the powder is applied to and compacted on the connecting surface.

5. A method for generative manufacture of a component, the method comprising:
providing a device for generative manufacture of parts, the device comprising a base plate which forms a connecting surface for applying and compacting powder in order to manufacture the component, wherein the base plate comprises a plurality of sheets, wherein the sheets are formed and arranged next to one another such that the connecting surface of the base plate is formed by lateral surfaces of the sheets;
producing the component by successively applying and compacting powder in thin layers on the connecting surface; and
separating the sheets individually or in groups from the produced component.

6. A method for generative manufacture of a component, the method comprising:
providing a device for generative manufacture of parts, comprising a base plate which forms a connecting surface for applying and compacting powder in order to manufacture the component, wherein the base plate comprises a plurality of sheets, wherein the sheets are formed and arranged next to one another such that the connecting surface of the base plate is formed by lateral surfaces of the sheets;
producing a sacrificial layer by applying and compacting powder on the connecting surface;
producing the component by successively applying and compacting powder in thin layers on the sacrificial layer; and
separating the sheets individually or in groups from the sacrificial layer.

7. The method of claim 6 , wherein the sacrificial layer is produced such that the sacrificial layer has a rounded support surface which adheres to the connecting surface.

8. The method of claim 6 , wherein the sacrificial layer is produced such that the sacrificial layer has a grid structure.
