A hobbyist technique for making rapid PCB prototypes using a standard 3D printer and copper tape. The workflow starts in KiCad with extra-thick traces, exports the layout to 3D CAD software where traces are extruded 2mm tall, then prints the board. Copper tape is applied over the raised trace edges to create conductivity. The result is a quick, low-cost alternative to waiting days for fabricated boards or using a CNC mill, suitable for simple microcontroller projects.
