Abstract

A method of manufacturing a part includes removing material with a cutting machine to form a plurality of segments, at least two of the segments including an anchoring structure, connecting two or more segments to form a first layer, and connecting two or more additional segments to form a second layer. The method also includes connecting the first layer to the second layer and connecting a support structure directly to two of the anchoring structures.

First claim

What is claimed is:

1. An additive manufacturing system, comprising:
a cutting machine, the cutting machine including a surface that is configured to receive a sheet of material; and
a controller configurable to cause the cutting machine to:
remove material from the sheet to form a plurality of segments, the plurality of segments including:
at least two of the segments that each include an anchoring structure protruding from an inner wall, the at least two segments, when connected to each other with a support structure that extends from a first anchoring structure to a second anchoring structure, forming a first layer, and
at least two additional segments that, when connected to each other, form a second layer of a plurality of layers.

2. The additive manufacturing system of claim 1 , wherein the controller is further configurable to cause the cutting machine to remove material to form the anchoring structures such that each anchoring structure protrudes inward such that a support structure, when connected to the anchoring structures, connects a single layer.

3. The additive manufacturing system of claim 1 , wherein the controller is further configurable to cause the cutting machine to remove material to form the anchoring structures such that each anchoring structure protrudes inward from a respective segment.

4. The additive manufacturing system of claim 1 , wherein the controller is further configurable to cause the cutting machine to remove material to form the first layer with a hollow interior and so that the anchoring structures protrude into the hollow interior.

5. The additive manufacturing system of claim 1 , wherein the controller is further configurable to cause the cutting machine to remove material to form a plurality of layers that, when connected, form a part.

6. The additive manufacturing system of claim 1 ,
wherein the controller is further configurable to cause the cutting machine to remove material to form a plurality of layers that, when connected, form a part having a plurality of support structures that are connected to a plurality of respective layers.

7. The additive manufacturing system of claim 1 , further comprising a plurality of support structures;
wherein the controller is further configurable to remove material to form a plurality of layers that, when connected, form a part;
wherein the plurality of support structures are connectable to the plurality of respective layers; and
wherein the plurality of support structures includes at least two support structures positioned so as to connect different segments of the first layer.

8. The additive manufacturing system of claim 1 ,
wherein the controller is further configurable to remove material to form a plurality of layers that, when connected, form a mold.

9. An additive manufacturing system, comprising:
a cutting machine, the cutting machine including:
a surface that is configured to receive a sheet of material; and
a cutting tool configured to remove material from the sheet when the sheet is supported on the surface;

a controller coupled to the cutting machine, the controller configurable to electronically communicate with the cutting machine to cause the cutting machine to:
form at least a portion of a part having a hollow interior, the part comprising:
a first segment forming a portion of a first layer;
a second segment forming a portion of the first layer, the second segment forming a joint with the first segment;
a third segment forming a portion of a second layer; and
anchoring structures, including at least one anchoring structure formed on at least one of the first segment, the second segment, or the third segment, wherein the at least one anchoring structure protrudes toward the hollow interior, and wherein a support structure, when connected to the anchoring structures, connects the first segment to the third segment.

10. The additive manufacturing system of claim 9 , wherein the controller is further configurable to cause the cutting machine to form each of the first segment and the second segment with a hollow portion at the joint.

11. The additive manufacturing system of claim 10 , wherein the controller is further configurable to cause the cutting machine to form the hollow portion with a shape that allows a fastener to extend within the hollow portion of the first segment and within the hollow portion of the second segment.

12. The additive manufacturing system of claim 9 , wherein the controller is further configurable to cause the cutting machine to form a protrusion on the first segment and a recess formed on the second segment.

13. The additive manufacturing system of claim 9 , wherein the controller is further configurable to cause the cutting machine to form the anchoring structure with a shape that protrudes inward such that a support structure, when connected to the anchoring structures, connects a single layer.

14. The additive manufacturing system of claim 9 , wherein the controller is further configurable to cause the cutting machine to form the anchoring structure with a shape that protrudes inward such that a support structure, when connected to the anchoring structures, connects a first layer to a second layer.

15. An additive manufacturing system, comprising:
a cutting machine;
a controller coupled to the cutting machine, the controller being configurable to:
receive an electronic representation of a part, the part having a plurality of layers;
determine that anchoring structures will be formed in the part;
identify one or more layers of the part that will include the anchoring structures;
determine locations for the anchoring structures within a layer, wherein the anchoring structures include protrusions that extend towards an interior of the layer and that are located within the layer;
determine a location for a support structure within the layer, wherein the support structure is configured to be connected to the anchoring structures with the anchoring structures being spaced apart by the support structure; and
generate instructions for forming, with the cutting machine, the layer that includes the anchoring structures for receiving the support structure.

16. The additive manufacturing system of claim 15 , wherein the instructions are configurable to cause the cutting machine to remove material from one or more sheets to form one or more layers that include the anchoring structures.

17. The additive manufacturing system of claim 15 , wherein the controller is further configurable to determine at least one of a size or a shape of the anchoring structures from a plurality of different sizes or shapes.

18. The additive manufacturing system of claim 15 , wherein the controller is further configurable to cause display of a prompt to a user for determining that the anchoring structures will be formed in one or more of the layers.

19. The additive manufacturing system of claim 15 , wherein the controller is further configurable to generate instructions for forming a plurality of segments for the one or more layers having anchoring structures.

20. The additive manufacturing system of claim 15 , wherein the controller is further configurable to generate instructions for forming a plurality of segments for the one or more layers having anchoring structures, wherein the anchoring structures are on inner walls of the segments.
