Using 3D printer UV resin to make a PCB

- In this video I describe the method to make a PCB using UV resin for 3D printing. There's a method to do it with a resin 3D printer, but I have simplified it so you don't need one to make a PCB. The resin is used to mask to copper plate using a transparency with the negative of the PCB and a UV light. Then the normal etching process does the rest.

They sell film that you put on the pcb and use uv light to cure it so it won't dissolve and expose the copper. This is same you are doing, but the film is much cheaper and easier to use than 3d printer resin. Of course, you can do it the old way and use a laser printer to print on glossy paper and iron it on the board. I had iffy luck doing it this way.
Using a laser to directly expose the film instead of printing seems ideal, some had great sucess, others not so much. Thanks for your video.
Have you ever tried use the 3D print resin as solder mask? I wonder if it resist de solder process.

That's an interesting application. I still would like to avoid using any nasty chemicals for this process, but will give it a go if get no luck. :) Definitely want to see more reports with details and numbers from you.
Thank you . This is nice
very cool, I am curious tho, how do you remove the resin from the copper after etching so you can apply flux and solder?
I am going to use silk screen emulsion for the mask instead of resin. Even spreading using spin coating
Actually that's a great idea! One problem I had with resin is that it's very easy to overcure it, making the traces thicker. I think you will have much more control of the curing time with the silk screen emulsion. Thank you very much!
I'll keep you posted
Hello aurangzebhaque2973 have you successfully attempted PCB using Screen Emulsion If yes Acknowledge me since I am unable to get UV resign Thank you
@@nfcradio4622 Hi. Not yet. Actually the spin coating machine needs to be improved. I need low end speed control to spread the chemical evenly on the board.
I have tried it using a brush to coat the pcb substrate. Although the layer thickness is uneven and excessively thick, the process does work. The chemical/emulsion does adhere to the copper surface, which was my main worry.
You can try it with a blank screen printing mesh. It works. The coat is thin and even
Safety note: most UV resins are very toxic to the skin before it is exposed. Please read the safety warning on your resin and wear gloves when needed. Your body can develop hyper allergies when getting skin contact with the resin.
Why not just use PCB with photoresist film?
ima try this with regular printer paper and you can't stop me.
the problem is the resolution of printed on transparent is not good enough so it becomes bottleneck from this DIY method
I am in.
If you are going through the trouble of getting it printed onto transparencies the resin steps are unnecessary all you need to do is iron the transparency on top of the pcb to transfer the toner to the pcb then etch it like normal.
