@MisterMaker it's Jet ECM, and it can be improved by adding a wire coaxially:
"..current density distribution of the electrolyte jet flow is not concentrated enough, which also affects the shape accuracy. Hence, a wire-preposed Jet-ECM method is proposed, in which a wire electrode is put in the high-speed jet and passes through the nozzle. The electrode can feed into the structure to follow the dissolution of workpiece so that a high aspect ratio will be ensured."

@MisterMaker it's actually pretty useful as is when it comes to prototyping #SheetMetal parts as well, since it inherently supports half-etching, which creates a preferential straight or curved creasing line.
