Default Home Brew PCBs

This is a topic that comes up many many times.

I'm going to try a new approach as this printer is silly money.

Ricoh SG 3110DN A4 Colour Gel Printer | eBay

It's prints the image directly onto the surface of the board with wax than can then be etched.

For 95 it's got to be worth a try, I've wasted more than that with failed etchings, exposures, toner transfers etc etc.

The resolution looks absolutely stunning. I'll post a few pictures of my results when it arrives.

Interesting question. How am I going to remove the wax once the board has been etched ?

Fine wire wool or some kind of solvent ?

IMHO:
Head for the kitchen and act like it's grease stuck to a frying pan.
(e.g. use a scouring pad and detergent)

Plan B: To get most of it off; place the board face down on a few sheets of paper towel and heat it with a clothes iron or something. The wax should melt and soak into the paper.

Er, I don't know what the eBay ad says but the ink is viscous gel, not wax. Also, I'm not too sure how you are going to pass a rigid board through a printer that doesn't have a straight feed path. To the best of my knowledge there is no ridged media support. If I'm wrong I'd love to hear about it, but I'm in a position to know quite a bit about Ricoh products .

jkuetemann - I've been studying the manual for the printer and you are quite correct.

It prints onto special sublimination paper then you can transfer that onto anything solid using a heat press.

Much like the toner transfer method except that this process is specially designed to transfer the image from the paper onto the solid surface.

I've had to buy a heat press as the iron just doesn't get to 400 degrees F for the transfer process.

As long as I can get a reliable repeatable process I'm not too worried about the cost. At the moment I'm paying over 150 for prototype boards which is OK for one offs but gets expensive very quickly.

150 pounds????????????? Surely not. There are a few companies doing PCB pooling, outsourcing manufacture and then mailing the cut-outs to the individual customers. Last year, I had four boards (all the same and 50 by 75 mm) done for $40 Australian.
There is a fellow from Romania (I think) who advertises cheap boards on the forum. I think he is "msdesigner".

I never got on with making my own pcbs. It rarely worked was messy and time consuming ending up with a amateur job.

I found a Chinese pcb supplier who turns the pcb's around in 2 weeks to my door. He is very cheapo, about 1/3 of the cost in the UK.
I get great professional looking pcb's and have never had a pcb fault.

I would try acetone (nail polish remover) to remove the wax. It works wonders on laser toner.

Now I discover that sublimination printing onto ally plate or mugs involves a special polyester coating on the medium to be printed.

This might just be another failed experiment.
