I have a project where I am etching Transparent TPU but it leaves a sticky residue behind after I etch it. I’ve tried using rubbing alcohol to clean it up but I haven’t been able to get a clean finish. Any suggestions?
Thanks in advance!

cool - this is a me too; at least a thought concept i’ve played around with (trying to engrave just about anything in the house that’s not PVC… )
what settings have you used? Did you mask?
I’ve currently come to the settings for etching at 1000s/25p
Here’s a picture of it masked versus unmasked. Doesn’t seem to make much of a difference.
that’s flexible TPU like for a phone case or something? or is it rigid?
It’s really flexible. Like pvc but I know it is not pvc.
