Abstract
A method of additively manufacturing an object includes successively forming a plurality of powder layers by depositing powder over a build platform using a powder-deposition apparatus. The method also includes successively forming a binder shell by bonding select regions of each one of the plurality of powder layers before forming each successive one of the plurality of powder layers using a binder-delivery apparatus. The binder shell encloses a portion of the powder. The method further includes densifying the portion of the powder bound by the binder shell using a consolidation apparatus.
Claims20
A method of additively manufacturing an object, the method comprising:
- successively forming a plurality of powder layers by depositing powder;
- successively forming a binder shell by bonding select regions of each one of the plurality of powder layers before forming each successive one of the plurality of powder layers,
- such that
- the binder shell is formed of bonded powder and
- the binder shell encloses a powder core formed of unbonded powder;
- tamping at least a portion of the unbonded powder bound by the binder shell to apply a compression force for packing the unbonded powder bound by the binder shell;
- and
- fusing the unbonded powder of the powder core and the bonded powder of the binder shell together to form a finished object.
