So from those pics it looks like the extruder oozes the resin on a rotating base in ever expanding circles. The resin would have to be sticky enough to attach to the previous layer. Then the rotation would have to be slow enough for the last layer to have been cured before the next layer was applied. And if the resin had a metallic content it would work as a signal reflector.
Heating the resin to the sticky / extrudable point must take a lot of energy which is not exactly abundant on spacecraft.
