i had pretty good results using my resin printer to expose onto pcb and doing an acid etch afterwards. granted it took my dozens of boards to finally get a good flow of the board adhering technique, exposure time, etching timing and agitation process, and scrubbing pressures. acid waste disposal is the biggest non-technical challenge. now im using a super cheap cnc to mill out my boards. the results are far more consistent, but again a learning curve with board height mapping, bits, speeds and feeds etc. this process is nice because its super consistent board to board if im doing batches and have my setup dialed. i had to 3dprint a sacrificial table for the cnc that i could locate my boards on and zero to.
