A way to "print" PCB

[christmas-light]

I have just seen this video and I think it is a very cool way to make pcb´s on, but wondering if it works :O

Here is the video

Hi:
Be sure to turn off your audio when you watch the video. That so-called music is irritating and terrible.

That looks like a good idea. I had read about some of it before. The problem is finding the printer(s) suggested.

I have an R340 which does CD printing, but haven't got around to trying it yet. I happened to have an extra CD tray and modified it, but that was as far as I got. I was put off by the large number of steps and the requirement for heating the board several times. I wonder if an iron would heat the board just as good as an oven? The only problem would be uniform heating of the PCB with an iron.

I had tried a method to transfer the toner pattern from a laser printer using a grill, but getting the proper amount of pressure was very difficult and controlling the heat was very difficult, so it hasn't worked too good so far.

I am going to try to get some aluminum plates to put in the grill so that pressure can be applied more evenly. The grill plates have a ridge around them and I can't get any pressure on the PCB. I tried using a wooden roller like used in crafts to apply decals, etc., but not very successful.

I also think that it is a great idea, I am going to try this one day ! :D
