The shallower screw channels for grooved feed keep the resin solid-bed height short and maintain high forward force in the grooves. This also builds up enough pressure at the end of the grooves to achieve adequate compression in the channels entering the heated extruder barrel.
This reduces feeding efficiency because it allows some melting in the grooves. Also deeper screw feed channels can be used to reduce the tendency to overfeed the extruder.
