Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. A nozzle cleaning fixture may be provided for the printer that is shaped to physically dislodge solidified build material and other contaminants from the nozzle. A robotic system for the printer can be used to maneuver the nozzle into engagement with the nozzle cleaning fixture for periodic cleaning, or in response to a diagnostic condition or the like indicating a clogged nozzle.
