Abstract

Examples disclosed herein relate to determining a manufacturing batch. In one implementation, the manufacturing batch relates to 3D printing. A processor may determine component parts of a product that. In one implementation, a processor determines a batch of the component parts related to different products based on a comparison to other potential batches.

First claim

What is claimed is:

1. A method of additive manufacturing of component parts for assembly in at least one product, the method comprising:
with a processor, receiving a list of parts to be manufactured from a same material;
with the processor, determining multiple potential batches of the parts, each batch comprising a number, orientation and placement of at least some of the parts to be manufactured;
with the processor, scoring each potential batch of the parts based on a comparison of support material associated with each batch and an assembly time associated with each batch;
with the processor, selecting a set of the potential batches that includes all the parts to be manufactured while minimizing support material used and assembly effort for the parts of that batch; and
with the processor, outputting the selected set of potential batches to a manufacturing environment to manufacture the component parts in the batches selected.

2. The method of claim 1 , further comprising, with the processor validating each potential batch by verifying an adequate amount of space and support between the parts of that batch.

3. The method of claim 1 , wherein parts are arranged in the potential batches such that a first part provides support for a second part in that batch.

4. The method of claim 1 , wherein the manufacturing environment comprises a number of three-dimensional printers and the processor outputs an STL file to the manufacturing environment.

5. The method of claim 1 , wherein determining multiple potential batches of the parts comprises referring to past manufacturing practice information regarding a similar list of parts to be manufactured.

6. The method of claim 1 , wherein scoring each potential batch of the parts comprises determining the distance between parts as arranged in a potential batch.

7. The method of claim 1 , further comprising dividing the parts into potential batches based on the parts of a past product order with a similarity to the at least one product being assembled, where the similarity is above a threshold.

8. The method of claim 1 , wherein the score of a potential batch is further based on at least one of: the number of parts in the potential batch, the parts of a certain type in the potential batch, the parts associated with a particular service level agreement of products associated with parts in the potential batch.

9. A method of additive manufacturing of component parts for assembly in at least one product, the method comprising:
with a processor, receiving a list of parts to be manufactured from a same material;
with the processor, determining multiple potential batches of the parts, each batch comprising a number, orientation and placement of at least some of the parts to be manufactured;
with the processor, scoring each potential batch of the parts based on a comparison of support material associated with each batch and an assembly time associated with each batch;
with the processor, selecting a set of the potential batches that includes all the parts to be manufactured while minimizing support material used and assembly effort for the parts of that batch; and
with the processor, outputting the selected set of potential batches to a manufacturing environment to manufacture the component parts in the batches selected; the method further comprising:
creating an STL file associated with a first potential batch;
determining an amount of support material based on surface triangles indicated in the STL file; and
determining the score for the first potential batch based on the amount of support material.

10. The method of claim 1 , further comprising determining a first potential batch based on a genetic method to create a potential batch from a list of parts.

11. The method of claim 10 , wherein the genetic method comprises creating multiple gene representations of different batches of parts combined into a chromosome representation of the batches used to create the parts associated with a group of products.

12. The method of claim 1 , further comprising:
determining the amount of support material used to create each potential batch;
determining assembly information for the different potential batches; and
select one of the potential batches for output based on a comparison of the amount of support material and assembly information associated with the potential batches.

13. The method of claim 12 , further comprising determining component parts of the at least one product based on the similarity of the at least one product to a product in a past order.

14. The method of claim 1 , further comprising determining 3D print partition planes associated with each of the potential batches.

15. The method of claim 1 , further comprising selecting one of the potential batches based on weighted factors including at least one of: the number of parts in the potential batch, the parts of certain type in the potential batch, and the parts associated with a particular service level agreement of the at least one product associated with parts in the batch.

16. A method of additive manufacturing of component parts for assembly in at least one product, the method comprising:
with a processor, receiving a list of parts to be manufactured from a same material for a current product;
wherein the processor has
a storage to store information related to manufacturing practices of past products;
the processor further to:
determine patterns of component parts associated with different products based on the stored information;
determine individual components of the current product for manufacturing based on the determined patterns; and
determine a batch of the determined components to be manufactured together; and

with the processor, outputting the batch of determined components to a manufacturing environment to manufacture the component parts in the batches selected.

17. The method of claim 16 , wherein determining individual components comprises determining individual components based on a pattern associated with a past product with a similarity level above a threshold with the current product.

18. The method of claim 16 , wherein the processor is further to determine 3D print partition planes to be associated with the determined set of components based on partition planes associated with the past products.

19. The method of claim 16 , wherein the processor is further to determine a manner of dovetailing the components to be reassembled to create a product.

20. The method of claim 16 , wherein determining a batch comprises:
determining the amount of support material used to create different sets of potential batches of the same set of parts;
determining assembly information for the different sets of potential batches; and
selecting one of the sets of potential batches for output based on a comparison of the amount of support material and assembly information associated with the sets of potential batches.
