Is your research about etching or printing more generally?
If yes say so directly in your Title/ question/ aim
How do you know that the etching method that you want to test is the best method for your needs?
Which alternative non-toxic etching methods have you researched?
Which criteria are you using to evaluate potential methods?
Would it be possible to list all the alternatives and compare them with your needs using a table/ form?
That’s all for me for the weekend!

It might help if you briefly answer these questions.
