I always wanted to be able to make microscopic structures myself. I saw the micro eiffel tower in the internet and that impressed me. I mean I'm not going to try to make integrated circuit, but simply metallic structures like eiffel tower or other tiny models.

how to find a photoresistI'm not saying that you shouldn't pursue this. I just want to be sure that you know that the metalcontaining leftover solution after etching is not safe to introduce into the general environment. There are definitely ways for you to safely and responsibly dispose of it.

BTW, for DIY projects like this, the Make Magazine website is a great resource:

https://www.jameco.com/webapp/wcs/st...gDrillDownView Can you use such boards with the photoresist already on them? That will probably be a lot more uniform coating than you can apply yourself... And I did a Google search from the Jameco website for photoresist, and got lots of useful hits: https://www.jameco.com/webapp/wcs/st...type=jamecoall Does any of that help? EDIT  at that Jameco search page, type photoresist into the Item #1 Google Search option box...

The idea of buying ready photoresist applied copper clads is good idea but I don't know If i'll be able to strip the photoresists from them and use it.

I have to start from something so I think I'll just buy a general purpose photoresist for now and see if it works ;)

https://ikonicsimaging.com/wp/shop/p...gn=photoresist They have a customer service 800 number listed on that page. Maybe give them a call to see if they offer some liquid photoresist solution in addition to their photoresist films...
