Additive manufacturing with powder and densification material dispensing
An additive manufacturing apparatus includes a platform, one or more supports positioned above the platform, an actuator, 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, 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 to form a volume of the layer having powder and binder material and corresponding to a cross-sectional portion of a part being built, a third dispensing system configured to deliver a densification material to the layer of powder or the combined layer of powder and binder material, and an energy source configured to emit radiation toward the platform so as to solidify the binder material.
