An extrusion construction system may include an extrusion nozzle configured to extrude construction material through an outlet onto an external surface, the extrusion nozzle including an excess flow port disposed substantially adjacent an edge of the outlet, an imaging device coupled to the extrusion nozzle, and a controller configured to adjust the rate of material flow through the extrusion nozzle in response to receiving one or more images captured by the imaging device showing excess material being extruded through the excess flow port.
