Figure 5.

The process for forming a line combining clearing techniques and multiplexing. Starting with a random particle distribution in (a). A focused point sweep is then used “below” the line, with the results shown in (b). This is repeated “above” the line, clearing the area and agglomerating some particles into the line, resulting in (c). Increasing order Bessel functions are then cycled up resulting in (d). Finally the line is shaped and reinforced through a combination of switching low impulse twin traps (e) and applying a static standing wave (f), resulting in the line with a cleared area around it, as shown in (g). The blue scale bars are 1 mm. This process is shown in action in Supplementary Video 2.
