I'm thinking this technology would be suitable for building models for proof of concept like building architecture or manufacturing.
example you want to find the replacement for your broken tail lights on a rare old volkswagen beetle assuming it's obsolete and they don't make it anymore.
If you manage to find the exact dimensions or schematics of the parts from the internet I would imagine you can "print" it out using a 3d printer.
Then take this 3d model to an injection mould maker and get him to produce a mould, and from that mould inject resin and coloring to re-produce the part that you need. You can even re-produce old toys.
