Hello, I am trying to engrave on black Polypropylene and I am having no luck yet. The end result looks very melted, it is not a nice crisp design.
This is the product I am trying to do engraving on:
Anybody has had any luck with such material? If so, what settings did you use?
The plastic is about 1.5 millimeters thick and the case is 1" high when closed.
