Abstract
The present disclosure is drawn to a material set including a powder bed material and a binder fluid. The powder bed material can be from 80 wt % to 100 wt % metal particles having a metal core and a thin metal layer on the core, and the metal particles having a D50 particle size distribution value ranging from 4 μm to 150 μm and the thin metal layer having an average thickness from 20 nm to 2 μm. The binder fluid can adhere a first portion of the powder bed material relative to a second portion of the powder bed material not in contact with the binder fluid.
Claims18
A material set for three-dimensional printing a metal article, comprising:
- a powder bed material, comprising from 80 wt % to 100 wt % metal particles having a metal core and a metal layer on the core, the metal particles having a D50 particle size distribution value ranging from 4 μm to 150 μm and the metal layer having an average thickness from 20 nm to 2 μm;
- and
- a binder fluid comprising a binder to adhere a first portion of the powder bed material relative to a second portion of the powder bed material not in contact with the binder fluid, wherein the binder and the first portion of the powder bed material when adhered together form a green three-dimensional object.
A method of three-dimensional printing a metal article, comprising:
- spreading a powder bed material to form a powder layer having a thickness of from 20 μm to 400 μm, wherein the powder bed material includes from 80 wt % to 100 wt % metal particles having a metal core and a metal layer on the core, the metal particles having a D50 particle size distribution value ranging from 4 μm to 150 μm and the metal layer having an average thickness from 20 nm to 2 μm;
- selectively binding, with a binder fluid comprising a binder, a first portion of the powder bed material relative to a second portion of the powder bed material not in contact with the binder fluid, wherein the binder and the first portion of the powder bed material when adhered together form a green three-dimensional layer within the powder;
- and
- building up additional green three-dimensional layers by sequentially repeating the spreading and the selectively binding of the powder bed material until a green three-dimensional metal article is formed.
