The day will come when additive technology can compete with conventional methods but this sure is nowhere near. For instance, it’s routine to layout and purchased 2 or 4-layer PCBs from China suppliers with 10 mil traces and spaces. By contrast this thing looks like what I used to do with mylar tape in the 70’s. If it can’t make circuits with useful component and trace density, it doesn’t matter if it’s sitting next to my desk because I can’t use it for anything practical.
I’d personally love to print replacement parts for my old 486 PC and so would a lot of other DOS old salts. Tell me when the printers get to that stage!
