Abstract

The invention relates to a device and a method for producing three-dimensional shaped parts by means of a layer construction method on a construction field in a construction space of a device, wherein materials are supplied to and discharged from the construction space. A supplying and discharging of all materials is carried out in a spatial direction of the device.

First claim

What is claimed is:

1. A production machine for producing three-dimensional molded parts on a construction field in a construction space, wherein materials are fed to and removed from the construction field,
characterized in that
the production machine has a top side and an opposing bottom side, a first vertical side and an opposing second vertical side, a third vertical side and opposing fourth vertical side, wherein the first and third sides are generally orthogonal;
wherein the production machine is a machine for layered construction of the molded parts and includes a coater and a print head,
the production machine requires a construction container onto which material is applied during a construction process; and the production machine is prepared for receiving the construction container from one of the sides; and for receiving a supply of a consumable material including a powder, slag or liquid from the same side;
wherein the coater has an elongated reservoir that applies the consumable material over the construction field.

2. The production machine of claim 1 , further characterized by the following:
the construction container is fed to and removed from the production machine by a handling device via one or more interfaces of the handling device.

3. The production machine of claim 1 , wherein the one side is a top side of the production machine.

4. The production machine of claim 1 , wherein one side is a front side, right side, back side, or left side of the production machine.

5. A production system including the production machine of claim 1 , wherein the production system moves the construction container from the top of the production machine by lifting upward and moves it to an unpacking position, and provides a new construction container to the top of the production machine by lowering downward.

6. The production machine of claim 1 , wherein the supply of the consumable material is provided in a construction material container.

7. The production machine of claim 1 , wherein the production machine includes the construction container.

8. The production machine of claim 1 , wherein the supply of consumable material includes a canister filled with a binder provided on the same side.

9. The production machine of claim 3 , wherein
the construction container is fed to and removed from the production machine by a handling device via one or more interfaces of the handling device.

10. The production machine of claim 9 , wherein
a handling device is further provided that can be made to engage with the production device, thereby allowing materials to be fed and/or removed.

11. A production system comprising several of the production machines of claim 10 , wherein
which are jointly operated, and
a supply system which charges the several production devices.

12. The production system of claim 11 , wherein the several production devices are arranged such that the materials can be fed and removed in a linear arrangement or in a circular arrangement.

13. The production machine of claim 1 , wherein the consumable material includes a powder material and a liquid material, wherein the liquid material is provided in a container and the powder is provided in a different container, wherein the construction container, the container including the powder, and the container including the liquid are all provided to the production machine on the same side.

14. The production machine of claim 1 , wherein the reservoir of the coater moves over the construction field and has an outlet.

15. A production system comprising:
a production machine for producing three-dimensional molded parts on a construction field in a construction space, wherein materials are fed to and removed from the construction field,
wherein the production machine has a top side and an opposing bottom side, a first vertical side and an opposing second vertical side, a third vertical side and opposing fourth vertical side, wherein the first and third sides are generally orthogonal;
wherein the production machine is a machine for layered construction of the molded parts and includes a coater,
the production machine requires a construction container onto which material is applied during a construction process; and the production machine is prepared for receiving the construction container from one of the sides; and for receiving a supply of a consumable material including a powder, slag or liquid from the same side;
characterized in that the production system comprises a handling device for 1) removing a container including the consumable material from an area of the production machine and 2) positioning the container of consumable material, thereby allowing materials to be fed into the production machine and/or removed from the production machine;
wherein the system comprises several of the production machines which are jointly operated, and a supply system includes the handling device and which charges the several production devices with separate containers of the consumable material;
wherein the supply system includes a connecting tool which connects to one or more interfaces of a container of the consumable material.

16. The production system of claim 15 , wherein the connecting tool includes bolts, hooks or pawls.

17. The production system of claim 16 , wherein the supply system is mounted above the production machine.

18. The production system of claim 17 , wherein the supply system includes a rail system on which a beam hoist moves in a longitudinal direction.

19. The production machine of claim 1 , wherein the reservoir of the coater has an elongated funnel-shape.

20. The production system of claim 5 , wherein the reservoir which is filled by a container including the consumable material, wherein the container including the consumable material has an inclined surface.

21. The production system of claim 20 , wherein the container for the consumable material has an opening for filing the reservoir.

22. The production machine of claim 5 , wherein the production system includes a conveyor belt.
