When it comes to making PCBs at home really quickly, there’s not much to improve upon with Ryan‘s bodged up Epson printer that prints an etch mask directly on a piece of copper clad board.
Like most of the direct to copper PCB printer conversions we’ve covered ( 1, 2, 3 ), [Ryan]‘s build relied on an Epson printer and Mis Pro yellow ink. The Mis Pro ink is one of the most etch-resistive substances that can be shot out of an inkjet printer, and Epson printer cartridges use a piezo pump that is perfect for squirting ink out on command.
After tearing the printer apart and lifting the print head a bit, [Ryan] needed a proper feed system to control where on the copper he was printing. He managed to make a board carrier out of a sheet of aluminum. By taping down the copper clad board, everything seems to work phenomenally.
After the break you can check out how fast [Ryan] can print out a fully etch-resisted PCB. It’s not improbable that he could produce a few dozen boards an hour; something our toner transfer PCB production method would kill for...!!!
