Abstract
Hybrid additive manufacturing methods include building a green state additive structure, wherein building the green state additive structure comprises iteratively binding together a plurality of layers of additive material using a binder, and joining the green state additive structure to a base structure to form a hybrid article.
Claims20
A hybrid additive manufacturing method comprising:
- building a green state additive structure, wherein building the green state additive structure comprises iteratively binding together a plurality of layers of additive material using a binder;
- and,
- joining the green state additive structure to a base structure to form a hybrid article.
A hybrid additive manufacturing method comprising:
- building a green state additive structure, wherein building the green state additive structure comprises iteratively binding together a plurality of layers of additive material using a binder;
- applying a heat to the green state additive structure to at least partially remove the binder to produce an at least partially sintered additive structure;
- and, joining the at least partially sintered additive structure to a base structure to form a hybrid article.
A hybrid article comprising:
- a base structure comprising a surface;
- and,
- a sintered additive structure joined to the surface of the base structure, wherein the sintered additive structure comprises a plurality of layers of additive material initially fused together via a binder that was subsequently removed.
