Abstract
A three-dimensional printing system is for manufacturing and post-processing a three-dimensional article. The system includes a housing, a blower, and a residue trap. The housing is for surrounding the three-dimensional article during the post process and includes an air inlet and an air outlet. The blower includes an inlet and an outlet. The outlet supplies pressurized air to the air emitting nozzle. The residue trap is coupled between the housing air outlet and the inlet of the blower. The air circulates around a loop from the blower outlet, to the air inlet of the housing, out of the air outlet of the housing, and to the inlet of the blower.
