Abstract

An example multi-dimensional component building system includes a first chamber having at least one base disposed therein, a second chamber adjacent to and in fluid communication with the first chamber through a first door, and a third chamber adjacent to and in fluid communication with the second chamber through a second door. The second chamber is fluidly sealed from the first chamber if the first door is in a closed position. The second chamber is configured to receive the at least one base via a first transfer mechanism if the fluid parameters of the first chamber are approximately equal to the fluid parameters of the second chamber. The second chamber includes a directed heat source and a build-up material configured to form a component on the at least one base by melting or sintering. The third chamber is fluidly sealed from the second chamber if the first door is in a closed position. The third chamber is configured to receive the at least one base, having a formed component disposed thereon, via a second transfer mechanism if the second door is in an open position. The fluid parameters of the second chamber are not substantially affected by fluid communication with the first chamber or the third chamber.

First claim

What is claimed is:

1. A method of building a multi-dimensional component comprising:
providing a first chamber, a second chamber, and a third chamber, wherein the first chamber and second chamber are connected by a first door and the second chamber and the third chamber are connected by a second door, wherein the first door fluidly seals the first chamber from the second chamber and the second door fluidly seals the second chamber from the third chamber, wherein a first base is disposed in the first chamber;
determining fluid parameters in the second chamber if the first door and second door are in a closed position;
maintaining fluid parameters approximately equal in the first chamber, the second chamber, and the third chamber prior to either the first door and the second door moving from a closed position to an open position;
moving the first base from the first chamber to a second chamber through the first door in an open position;
closing the first door and the second door such that the second chamber is fluidly sealed from the first chamber and the third chamber;
melting a build-up material with a direct heat source to form a component on the first base in the second chamber;
maintaining fluid parameters approximately equal in the second chamber and the third chamber prior to moving the second door from the closed position to the open position after forming the component;
opening the second door; and
moving the formed component and the first base from the second chamber to a third chamber through the second door.

2. The method of claim 1 , including the steps of:
providing a second base in the first chamber;
maintaining fluid parameters approximately equal in the first chamber and the second chamber;
opening the first door and the second door; and
moving the second base into the second chamber while simultaneously moving the first base into the third chamber.

3. The method of claim 1 , including the steps of:
moving the build-up material from a second platform to a cavity formed by a wall between the second platform and a first platform, the base, and side walls of the second chamber; and
melting a portion of the build-up material with the direct heat source to form a layer of the component on the first base in the second chamber.

4. The method of claim 3 , wherein the step of moving the build-up material is performed by a dispenser arranged to move across the first platform and second platform.

5. The method of claim 3 , including the steps of:
lowering the first platform and base after melting the portion of the build-up material; and
raising the second platform after melting a portion of the build-up material.

6. The method of claim 1 , wherein the fluid parameter is oxygen content within the second chamber.

7. The method of claim 1 , wherein only one of the first door and second door is in an open position and only one of the first door and second door is in a closed position, the first chamber and the third chamber have different fluid parameters.

8. The method of claim 1 , wherein the step of determining fluid parameters comprises monitoring the fluid parameters with a sensor in each of the first chamber, the second chamber, and the third chamber, wherein each sensor is in communication with a controller.

9. The method of claim 1 , including the step of:
removing excess build-up material using tooling in the third chamber.

10. The method of claim 9 , wherein the tooling is one of a vacuum or a brush.

11. A method of building a multi-dimensional component comprising:
providing a first chamber, a second chamber, and a third chamber, wherein the first chamber and second chamber are connected by a first door and the second chamber and the third chamber are connected by a second door, wherein the first door fluidly seals the first chamber from the second chamber and the second door fluidly seals the second chamber from the third chamber, wherein a first base is disposed in the first chamber, wherein a sensor is disposed in each of the first chamber, the second chamber, and the third chamber;
monitoring the fluid parameters using the respective sensor in the first chamber, the second chamber, and the third chamber;
controlling the fluid parameters in the first chamber, the second chamber, and the third chamber using a controller such that the fluid parameters are approximately equal prior to either the first door or the second door moving from a closed position to an open position;
moving the first base from the first chamber to a second chamber through the first door in an open position;
closing the first door and the second door such that the second chamber is fluidly sealed from the first chamber and the third chamber;
melting a build-up material with a direct heat source to form a component on the first base in the second chamber;
controlling the fluid parameters in the first chamber, the second chamber, and the third chamber using a controller subsequent to the step of melting such that the fluid parameters are approximately equal in the second chamber and the third chamber prior to moving the second door from the closed position to the open position after forming the component;
opening the second door; and
moving the formed component and the first base from the second chamber to a third chamber through the second door.

12. The method of claim 11 , including the steps of:
providing a second base in the first chamber;
maintaining fluid parameters approximately equal in the first chamber and the second chamber;
opening the first door and the second door; and
moving the second base into the second chamber while simultaneously moving the first base into the third chamber.

13. The method of claim 11 , including the steps of:
moving the build-up material from a second platform to a cavity formed by a wall between the second platform and a first platform, the base, and side walls of the second chamber; and
melting a portion of the build-up material with the direct heat source to form a layer of the component on the first base in the second chamber.

14. The method of claim 13 , wherein the step of moving the build-up material is performed by a dispenser arranged to move across the first platform and second platform.

15. The method of claim 13 , including the steps of:
lowering the first platform and base after melting the portion of the build-up material; and
raising the second platform after melting a portion of the build-up material.

16. A method of building a multi-dimensional component comprising:
providing a first chamber, a second chamber, and a third chamber, wherein the first chamber and second chamber are connected by a first door and the second chamber and the third chamber are connected by a second door, wherein the first door fluidly seals the first chamber from the second chamber and the second door fluidly seals the second chamber from the third chamber, wherein a first base is disposed in the first chamber, wherein a sensor is disposed in each of the first chamber, the second chamber, and the third chamber;
monitoring the fluid parameters using the respective sensor in the first chamber, the second chamber, and the third chamber;
controlling the fluid parameters in the first chamber, the second chamber, and the third chamber using a controller such that the fluid parameters are approximately equal prior to either the first door or the second door moving from a closed position to an open position;
