Comment on DissolvPCB enables fully recyclable 3D-printed circuit boards with liquid metal conductors

I wonder if you could use HIPS instead of PVA. Still dissolves, but in limonene rather than water, so inadvertant exposure on a rainy day wouldn’t ruin your circuit board. At the same time, the metal should still be recoverable unless there’s some chemical reaction between gallium and citrus oil that I don’t know about.
