History: Maskless Photolithography with Conductive Fabric and DIY Laser Galvanometers

I use max to control a DIY laser machine. The max patch takes pixel graphics. (i will make another page to show how to make the DIY laser machine....)

Firstly coat the conductive fabric with photosensitive resin (those for SLA printing).

I use vinegar and hydrogen peroxide, salt for etching, and Silver Ripstop Shieldex Bremen from Statex.

coat it with photosensitive resin, use "resistive dye-alike method" to protect the part by laser curing it

after laser curing the exposed part are harden and it looks like this

rinse it with alcohol to remove the undeveloped resin as much as you can, then put the fabric in solution of vinegar and salt and hydrogen peroxide and wait for 30 minutes to an hour. (this is the part i want to improve with water soluble photosensitive resin)

After "etching"

it also gives photo level result with conductivity!

test the resistance
