Claims18
An additive manufacturing apparatus, comprising:
- a coater comprising:
- a plurality of troughs disposed in a side-by-side configuration, wherein each trough of the plurality of troughs includes a plurality of side-by-side deposition valves, and
- at least one reservoir communicating with at least one trough of the plurality of troughs, wherein the at least one reservoir includes a feed valve operable to selectively block or permit flow of a powder from the at least one reservoir to the at least one trough.
An additive manufacturing method, comprising:
- positioning a coater adjacent a worksurface, the coater comprising a trough including a plurality of side-by-side deposition valves;
- depositing powder from the trough onto the build platform through at least one of the deposition valves;
- and
- using radiant energy to fuse the powder.
