What's interesting is when you showed list of items that you shouldn't cut It talked about pleather/artificial leather emitting chlorine gas. I could have sworn when I got my creality falcon 2 pro that it came with some sample pleather items that I could engrave on. I'm wondering if they consider engraving safer than cutting these types of material?

[JesseSchoch]

consider printing TPU for your way wipers

Pretty sure all that spray is is developer for dye penetration testing.
