They propose to inject polymer into your body... somewhere... apparently creating a polymer-filled 3D-printing chamber right inside your body cavity, and then 3d-print in it with sound waves.
What is the use of those 3d-printed solid polymer things for surgical purposes, how to get rid of those solid things afterwards and how to get out the rest of the unneeded polymer fluid seem to be unanswered questions at the moment.
