Additive manufacturing with dispensing of multiple powders
An additive manufacturing apparatus includes a platform, one or more supports positioned above the platform, an actuator, a first dispenser system configured dispense a plurality of successive layers of powder onto a build area supported by the platform, a first binder material dispenser configured to selectively dispense a first binder material on a voxel-by-voxel basis to an uppermost layer of powder in the build area, and an energy source configured to emit radiation toward the platform so as to solidify the binder material. The first dispenser system includes a first powder dispenser that is attached to and moves with a first support from the one or more supports and is configured to selectively dispense a first powder onto the build area, and a second powder dispenser that is configured to selectively dispense the second powder onto the build area.
