Abstract: In one example, a device for dispensing build material powder in an additive manufacturing machine includes a first dispenser including a first scoop rotatable in a first direction to scoop build material powder into the first dispenser, a second dispenser including a second scoop rotatable in a second direction opposite the first direction to scoop build material powder into the second dispenser, and a leveler between the first dispenser and the second dispenser.

Abstract: In one example, a memory having instructions thereon that when executed cause a 3D printing system to repeatedly form each of multiple successive layers of powdered build material on a platform and apply a functional agent to build material in each layer, create a pressure difference across a thickness of build material on the platform, and increase the pressure difference over an extent of build material on the platform as the build material on the platform gets thicker.
