Fig. 8. Visualization of the integration trajectory of the wire capillary to attach the filament to the substrate and to render the meander shape of the filament around the guiding posts of the substrate.

The origin of the trajectory is located at the bottom of attachment structure A and is highlighted by a sphere. The wire capillary moves vertically and then horizontally out of the attachment structure, placing the free air ball at the beginning of the filament in the recess of attachment structure A. Next, the wire capillary moves toward the first guiding post to wind the filament around the post. By alternating the latter sequence, the trajectory places the filament in a meander shape over the substrate and ends above attachment structure B. A stitch bond is utilized to finalize the second attachment and truncate the filament wire
