  Step 1

  1. Create a circuit board model using any program of an InkScape type (inversion picture. Later, we’ll explain why inversion).
  

  2. Convert it into the gcode.

  3. Stick the vinyl film onto the copperized plate of glass fiber.
  

  4. Place the vinyl coated glass fiber plate onto the work table of the 3D printer, and turn on the 3D printer in the laser cutting / engraving mode.
  

  5. The laser will burn on the vinyl film an inversion image of the pattern to be resulted.
  

  6. Dissolve the iron chloride powder in water (do not worry, no chemical reaction will follow).
  

  7. Put the glass fiber plate into the iron chloride water for 45-60 minutes.

  Step 2

  The copper on the glass fiber surface, free of the film after the laser burning, will react with the iron chloride (copper etching chemical reaction) and goes into the solution leaving clean glass fiber in the contours of the inversion image.

  Then, make holes for the necessary connectors with a small drill, or leave as is, and solder the connectors on top of the circuit board.

  Step 3

  So, we have told you how you can create a small shop - laboratory for circuit boards manufacturing, using a 3D printer and a laser.

  This technology is certainly not perfect and has several shortcomings, but it is efficient and can be used at home and small laboratories.
