ABSTRACT:
An inert gas dispenser for mounting to a process equipment functional window is provided to dispense an inert gas in a laminar flow at an effective velocity across the exposed surface to form a curtain of inert gas across the exposed surface to prevent a build-up of chemical by-product from the powder material during laser sintering. The gas flow rate is characteristic of a flow geometry having a Reynolds number below the turbulent range. The diffuser is used in a laser sintering system.
