Abstract: Examples of an inlet to enable a forced air flow to enter a build material container in a 3D additive manufacturing system are described. In one case, the inlet has a structure having an inner face and an outer face forming at least one aperture through the structure through which forced air flows in use. The inlet has a longitudinal axis and the inner face and outer face are non-aligned along at least one axis which passes through each of inner face and the outer face and is substantially parallel to the longitudinal axis.
