Just came across this paper from Mexico.
They sure know how to do a lot with a little.

Especially cool that it can handle surface mounts (claims downto 0.5 mm but I wonder if my banana fingers could do that)
In the paper they mention that threading the wire was the most time consuming part.
After the threading you would scrape the insulation on the component side and then just solder the components.
I was thinking, maybe a toolhead with an insulated copper thread could "sew" its way somehow or maybe one could make small "bows" and use the regular toolhead to glue the bowed thread, making the plastic sheet as you go.
