Abstract
An additive manufacturing apparatus includes: first and second spaced apart side walls extending along a pre-defined path and defining a build chamber therebetween; one or more build units mounted for movement along the pre-defined path, the one or more build units including at least one of: a powder dispenser positioned above the build chamber; an applicator configured to scrape powder dispensed into the build chamber; and a directed energy source configured to fuse the scraped powder.
Claims19
An additive manufacturing method, comprising:
- positioning one or more build units over a build chamber defined by first and second spaced-apart side walls which extend along a pre-defined path;
- moving the one or more build units relative to the build chamber along the pre-defined path;
- using the one or more build units to deposit powder onto a build platform contained in the build chamber and form a layer increment of powder thereon;
- using the one or more build units to direct a beam from a directed energy source to fuse the powder;
- moving at least one of the build platform, first and second spaced-apart walls, and one or more build units by the layer increment;
- and
- repeating in a cycle the steps of depositing, directing, and moving to build up a part in a layer-by-layer fashion until the part is complete.
