Abstract
A method of forming structure on a component includes: providing a component having a first surface; adhering powder to the first surface; and directing a beam from a directed energy source to fuse the powder in a pattern corresponding to a layer of the structure.
Claims14
A method of forming a structure on a component, comprising:
- providing the component having a first surface;
- applying an adhesive to the first surface;
- applying a powder to the adhesive and adhering some of the powder to the first surface to form adhered powder such that any powder not adhered to the first surface is excess powder;
- removing the excess powder;
- directing a beam from a directed energy source to fuse the adhered powder in a pattern corresponding to a layer of the structure, wherein a cycle of adhering the powder to form adhered powder, removing excess powder, and directing the beam to fuse the adhered powder is repeated to build up the structure in a layer-by-layer fashion until the entire component is complete;
- and
- wherein the steps of applying an adhesive, applying a powder, removing excess powder, and directing a beam from a directed energy source occur without the use of any powder bed.

A method of forming a cooling channel on a component, comprising:
- providing a component having a first surface;
- applying an adhesive to the first surface;
- applying a powder to the adhesive and adhering some of the powder to the first surface;
- removing excess powder;
- directing a beam from a directed energy source to fuse the powder in a predetermined pattern;
- and
- repeating in a cycle the steps of adhering, removing, and fusing to build up the cooling channel in a layer-by-layer fashion, wherein the cooling channel includes spaced-apart walls which define at least one open channel therebetween;
- and
- wherein the steps of applying an adhesive, applying a powder, removing excess powder, and directing a beam from a directed energy source occur without the use of any powder bed.
