1. A system for loading a build material powder supply container for 3D printing, the system comprising:
a dispenser to dispense a build material powder into a supply container;
a device to measure a density of the build material powder in the supply container to obtain a measured density;
a compactor to compact the build material powder in the supply container; and
a controller operatively connected to the dispenser, the measuring device and the compactor, the controller programmed to:
use the measured density to control a flow rate of the build material powder from the dispenser into the supply container, wherein when the measured density increases, the controller decreases the flow rate of the build material powder from the dispenser into the supply container; and
control the compactor to compact the build material powder in the supply container until the measured density reaches a threshold density.
