I'll be happy to give it a try, as an electronics enthusiast, I make a lot of boards. Will u be selling the resin?

Hello,
Im thinking about mikes methode ...
I never worked with 3d printable resin, so maybe its a dumb question.
But how will we get the resin off the copper after eching without hurting the board?
Isnt it very sticky?

Thank you..... as a pcb enthusiast, it's the first thing I'll try when I get my Peachy. Photo board can be difficult to get the exposure right and is relatively expensive. This method (if it works) should work every time. Bit worried about how good the adhesion will be and therefore whether the etchant will go under the cured resin. I have iso-propyl in stock so will try that first :-)
I have to say, if it is effective, PCB production alone will be one major reason for buying a peachy.
will we sell a resin that will work for this?
Only time and experimentation will tell, and it is very likely that some other third party resin will work better.
as for how to get the resin off... after the etching is done, I think it might come off quite quickly with a scraper. Isopropyl dissolves uncured resin but not cured resin.
perhaps eventually our flex resin could work for this, it might peal of like tape would.
If it does work effectively.... I will have a massive grin :-)
You may not need to remove the resin , or at least not all of it. If it is thin enough maybe you can solder through it. If it would serve as a solder resist or at least as a sealer, maybe a Dremel tool with an end mill or something could be used to just remove it from the solder pads.
Even if you want to remove it from the entire board I'm sure it can't be too hard with the right solvent (dependent on the resin used). I know many plastics can be easily dissolved with acetone but have no idea if acetone will dissolve cured UV resin like those from MakerJuice.
