DIY: artwork of a PCB regulating laser diode

3D-printers have non-stop unconstrained possibilities for home prolongation and fast prototyping. Now we can simply emanate most any indication in a 3D-program and 3D imitation it. But until now, usually few people have suspicion about a probability to 3D imitation wiring for this or that resolution (model).

Up to this day to make a circuit house for a antecedent one had to pore over it with a soldering iron or to sequence a brief prolongation run. However, many of us can make it regulating a required iron and a laser printer.

Though, this routine is not really appreciative possibly aesthetically or technologically. In this essay we would like to report another method.

Not usually any 3D printer though also any DIY Engraver will fit for it

or a constructor of a makeblock plotter xy type:

By a way, we can implement a diode laser roughly on any 3D-printer, environment it as an further or in place of a extruder. Diode lasers are tiny in distance and compact. Their comparatively tiny energy outlay compared with that of CO2 lasers is not a obstacle in this case.

So, what does a routine of a circuit house production during home or in a bureau demeanour like?

For this we need a copperized potion fiber plate, any dim vinyl film (any dim film that a laser can bake by will fit), iron chloride (sold plainly in stores of chemical reagents) and, of course, a diode laser commissioned on a 3D printer. Its energy outlay is not so really important, though we suggest to use a diode laser of some-more than 2W (2000 mW).

To implement a laser on any 3D printer is really easy …

How to implement it on an Ultimaker:

and on a WanHao DuPlicator  i3:

So, let’s begin:

  1. Create a circuit house indication regulating any module of an InkScape form (inversion picture. Later, we’ll explain because inversion).


  1. Convert it into a gcode.


  1. Stick a vinyl film onto a copperized picture of potion fiber.



  1. Place a vinyl coated potion fiber picture onto a work list of a 3D printer, and spin on a 3D printer in a laser slicing / cast mode.


  1. The laser will bake on a vinyl film an inversion picture of a settlement to be resulted.




  1. Dissolve a iron chloride powder in H2O (do not worry, no chemical greeting will follow)


  1. Put a potion fiber picture into a iron chloride H2O for 45-60 minutes.


The copper on a potion fiber surface, giveaway of a film after a laser burning, will conflict with a iron chloride (copper artwork chemical reaction) and goes into a resolution withdrawal purify potion fiber in a contours of a inversion image.

Then, make holes for a required connectors with a tiny drill, or leave as is, and solder a connectors on tip of a circuit board.

So, we have told we how we can emanate a tiny emporium – laboratory for circuit play manufacturing, regulating a 3D printer and a laser.

This record is positively not ideal and has several shortcomings, though it is fit and can be used during home and tiny laboratories.
