Abstract
According to an example, a green body may include from about 1 wt. % to about 20 wt. % of a metal nanoparticle binder and a build material powder, wherein the metal nanoparticle binder is selectively located within an area of the green body to impart a strength greater than about 3 MPa.
Claims15
A method, comprising:
- spreading a layer of a metal or metal alloy build material powder;
- selectively depositing from about 1 wt. % to about 20 wt. % of a metal nanoparticle binder onto the layer of the metal or metal alloy build material powder;
- and
- applying energy to form a green body from the layer of the metal or metal alloy build material powder and the metal nanoparticle binder deposited on the layer of the metal or metal alloy build material powder,
- wherein the metal nanoparticle binder is selectively located within a first area of the green body to impart a strength greater than about 3 MPa in the first area.

A method, comprising:
- spreading a layer of a build material powder;
- selectively depositing a first agent including from about 1 wt. % to about 20 wt. % of a metal nanoparticle binder onto the layer of the build material powder;
- selectively depositing a second agent including a polymer binder onto the layer of the build material powder, wherein the polymer binder is selected from the group consisting of polypropylene, polyethylene, low density polyethylene, high density polyethylene, polyethylene oxide, polyethylene glycol, polystyrene, polyphenyl ether, polyamide 11, polyamide 12, polymethyl pentene, polyoxymethylene, polyethylene terephthalate, polybutylene terephthalate, polyvinylidene fluoride, polytetrafluoroethylene, perfluoroalkoxy alkane, polyphenylene sulfide, and polyether ether ketone;
- and
- applying energy to form a green body from the layer of build material powder and the first and second agents deposited on the layer of the build material powder,
- wherein the first agent including the metal nanoparticle binder is selectively located within a first area of the green body to impart a strength greater than about 3 MPa in the first area.
