A technique for creating custom PCBs using 3D printing and copper tape involves designing the board in KiCad, extruding traces by 0.6mm in CAD software, 3D printing the board, then applying copper tape and cutting along the raised traces. The method produces single-sided boards with 2mm trace widths, requires careful slicer settings to avoid voids, and uses materials like PLA that are more flexible and heat-sensitive than traditional FR4. While easier than working with perfboards, the approach has limitations including difficult desoldering and material constraints.
