That just does not sound cheap. One envisions a cost-distributed 3D effort, with this used for certain critical parts.
- ben_w 2y agoI'd assume slow rather than expensive; if it's similar to other electroplating, think in terms of nm/s in the z-axis, 96,485 Amp-seconds* per mole of whatever metal you're putting down at a small (material dependent) number of volts of potential, so I'd guess OOM €10/kg process plus whatever the material cost is in the form of an electrolyte. * https://en.wikipedia.org/wiki/Faraday_constant https://en.wikipedia.org/wiki/Faraday_constant
- impossiblefork 2y agoI actually think it does. I'm imagining a human-sized tank, continuously growing things by electroplating, slowly, slowly, but eventually making something quite big. I find this concept very appealing. I don't quite understand how it though, because I have view of electroplating as something which is very different from this precise and presumably at least somewhat fast process.
- kube-system 2y agoIt sounds a lot like semiconductor manufacturing, except electrochemical instead of photochemical.
- cjbgkagh 2y agoIt’ll be like a resin printer, the hard part is the anode array which isn’t that hard, it seems that TFT screen manufacturers can make what’s needed and TFTs screens are really cheap.
