Fig. 2: The impact of AF on the geometric morphology of AJ printed line.
From: Enhanced aerosol-jet printing using annular acoustic field for high resolution and minimal overspray
a Original geometric morphology of an AJ printed line before acoustic focusing (AF). b Geometric morphology of the line printed continuously under AF ON. The linewidth (LW) has been significantly reduced, and the overspray has been suppressed to a lesser extent. c Geometric morphology of the line printed continuously with (b) after turning off AF. Both the LW and the overspray have been restored to their original condition. d Overview of an AJ printed line undergoing three consecutive states: AF OFF, ON, and OFF. e, f Converging and diverging processes of the AJ printed line during intervention and evacuation of AF. Vp is the printing speed, and lp is the length of transition zone. This proves the effectiveness and sufficiency of AF.
