1 . A method, comprising:

determining objects corresponding to a manufacturing period of three dimensional (3D) printing;

packing build volumes based on the objects;

simulating manufacturing powder degradation based on the build volumes;

determining a quantity of manufacturing powder consumption based on the manufacturing powder degradation; and

adjusting a manufacturing parameter based on the quantity of manufacturing powder consumption.

2 . The method of claim 1 , wherein determining the objects comprises selecting the objects based on object category.

3 . The method of claim 1 , further comprising determining a quantity of build volumes.

4 . The method of claim 3 , wherein determining the quantity of build volumes is based on a quantity of object packing amounts, quantity of object spacings, and a quantity of replicants.

5 . The method of claim 1 , further comprising:

determining the quantity of manufacturing powder consumption per object for each of the build volumes;

selecting a build volume with a smallest quantity of manufacturing powder consumption per object; and wherein

adjusting the manufacturing parameter comprises changing a batching rule based on the selected build volume.

6 . The method of claim 1 , further comprising determining whether a demand condition is satisfied.

7 . The method of claim 6 , wherein determining the objects corresponding to the manufacturing period is performed in response to determining that the demand condition is satisfied.

8 . The method of claim 6 , wherein determining whether the demand condition is satisfied comprises:

determining a Kullback-Leibler (KL) divergence between a first period distribution and a second period distribution; and

comparing the KL divergence to a threshold.

9 . The method of claim 6 , wherein the determining whether the demand condition is satisfied comprises determining whether a quality metric satisfies a quality check threshold.

a memory; and

a processor coupled to the memory, wherein the processor is to:

simulate manufacturing powder degradation quality metrics for a set of build volumes;

determine quantities of manufacturing powder consumption for the set of build volumes based on the manufacturing powder degradation quality metrics;

select a build volume with a smallest quantity of manufacturing powder consumption; and

change a manufacturing procedure based on the selected build volume.

11 . The apparatus of claim 10 , wherein the processor is to change the manufacturing procedure by changing a batching rule based on the selected build volume.

12 . The apparatus of claim 11 , wherein the processor is to change the manufacturing procedure by changing a build height rule based on the selected build volume.

13 . A non-transitory tangible computer-readable medium comprising instructions when executed cause a processor of an electronic device to:

determine that a demand condition is satisfied to produce a demand determination;

determine, in response to the demand determination, objects corresponding to a manufacturing period;

determine build volumes that include the objects;

determine a quantity of manufacturing powder consumption for each of the build volumes; and

adjust a batching rule based on the quantity of manufacturing powder consumption of each of the build volumes.

14 . The non-transitory tangible computer-readable medium of claim 13 , wherein the instructions when executed cause the processor of the electronic device to:

determine a build volume with a smallest manufacturing powder consumption; and

adjust the batching rule by changing the batching rule to a batch size of the build volume.
