Fahd,

wet etching is probably the worst way of structuring PMMA. Why would you
want to do it this way? You can mechanically mill, hot emboss, wire imprint,
injection mold, laser ablate or laser cut PMMA and each of these methods is
better than etching it.

Cheers
Holger

Hello everyone,

      I am using this service for the first time.

I want to do wet etching of PMMA substrate. Does anyone have any idea how to
do it. I want to make small channels in it.

thanking you in advance.
regards,
Fahd
