Classification: CPC B | IPC B

Claim 5:
6. A non-transitory machine-readable medium comprising instructions which when executed by a processor cause the processor to perform processing comprising:
in an additive manufacturing process, generating a first object from an initial bottom layer of the first object to a final top layer of the first object, by applying and selectively solidifying build material in correspondence with the first object on a layer-by-layer basis;
after the first object has been additively manufactured, determining a thermal diffusion model by determining a heat map of the final top layer of the first object;
generating a plurality of layers of unfused build material on the final top layer of the first object; and
generating an ancillary object on the layers of the unfused build material from an initial bottom layer of the ancillary object to a final top layer of the ancillary object, by applying the build material and selectively fusing the build material in correspondence with the ancillary object on the layer-by-layer basis, the ancillary object having a thermal profile based on the thermal diffusion model and reducing a thermal gradient of the first object during cooling.
