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
An additive manufacturing system comprising:
- a build platform;
- a powder-deposition apparatus configured to deposit powder such that a plurality of powder layers is successively formed over the build platform;
- a binder-delivery apparatus configured to deliver binder at select regions of each successive one of the plurality of powder layers such that a binder shell is successively formed;
- and
- a consolidation apparatus configured to densify a portion of the powder bound by the binder shell.
A method of additively manufacturing an object, the method comprising:
- successively forming a plurality of powder layers by depositing powder;
- and
- 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,
- wherein the binder shell encloses a portion of the powder.
An additively manufactured object made by a process comprising steps of:
- successively forming a plurality of powder layers by depositing powder;
- and
- forming a binder shell by bonding select regions of each one of the plurality of powder layers to successively form a plurality of shell layers of the binder shell before forming each successive one of the plurality of powder layers,
- wherein the binder shell encloses a powder core.
