3D-Printed Circuit Boards, For Solder-Free Printable Electronics

An anonymous reader writes "Check out the latest success of the OpenSCAD 3d-printed electronics library. To use it, you just need a 3D printer and some conductive thread. OpenSCAD generates a component holder, and conductive thread wraps it all together — no solder, no etching chemicals, no sending out for anything. The instructable takes you through all the steps from schematic to circuit, and includes a more useful example: the fully printed LED flashlight."

Not impressed, my vacuum tubes were plenty good enough for adding and subtracting. They're cheaper than those new "transistors" too. I can put an array of tubes together for much cheaper than you can put transistors on a board.
