Fig. 3

a–d Cross-section profile of AJ printed traces with different LW (a)~10 μm, (b) ~30 μm, (c) ~50 μm, (d) ~80 μm with AF ON/OFF. Source data are provided as a Source Data file. e Continuous AJ printing in a 2D orthogonal direction with AF switched intermittently, to verify the omnidirectional focusing of AF. Vp is the printing speed. f A high-density array (both LW and spacing ranging ~6 μm) printed by AF-assisted AJ. g LW of a continuously AJ printed trace with multiple AF ON/OFF varies in different directions.
