Abstract: A system for cleaning an additive manufacturing machine recoater includes a position module for sensing and/or determining a position of a recoater of the additive manufacturing machine and a gas manifold disposed in the additive manufacturing machine and configured to spray a pressurized gas on the recoater when the recoater is in at least one cleaning position. The system includes a valve configured to allow the pressurized gas to flow from a gas source to the gas manifold, and a valve control module configured to control the valve as a function of the position sensed and/or determined by the position module.

Abstract: A nozzle tip includes a nozzle tip body defining an upstream surface and an opposed downstream surface. An outlet orifice is defined through the nozzle tip body for fluid communication from a space upstream of the upstream surface to a space downstream of the downstream surface. The outlet orifice includes a cylindrical outlet portion defining an outlet axis, and a tapered inlet portion upstream of the outlet portion. The tapered inlet portion converges down towards the outlet axis in a direction from the upstream surface toward the downstream surface.
