The demo uses a modified laser-cutter to print, assemble and finish a working drone that then flies off the build plate, with only the tiniest human interventions.
It uses a multi-tip add-on that bolts onto the laser-cutter's head, and uses an accelerometer to locate itself in space over the build-plate. The add-on can dispense conductive silver paste and perform pick-and-place operations with a suction cup.
The control system integrates the laser with the special head: it tidies up the silver paste traces into sub-millimetre traces, thermally cures the paste to solder components together.
The money-shot is that robotically assembled drone taking off on its own, (almost) untouched by human hands.
