    I’m curious about the durability of these PCBs. They would be good for prototyping but how well would they handle high humidity environments?

      Yea these would definitely need a hydrophobic coating for any real-world use - PVA starts degrading above 70% humidity, so you’d probably want to seal it with something like acrylic conformal coating or even just a thin layer of epoxy if your going to use it outside a controlled environment.

      You might be able to coat them, but for long term applications I think you’d be better off etching FR4 the old fashioned way. This sounds like a huge breakthrough for low cost rapid prototyping, though.
