Thanks. That is a good rule for home use, for sure!
But this quote refers to cutting specifically, though etching would release the same things.
But in my last company manufacturing consumer devices, laser etching for date codes & other info was done on many parts, and I thought the were a with a blend of ABS… The marking done was very low power–just enough to produce a contrast color but not any depth to speak of.
And to check my sanity, I googled laser etching ABS components, and found this:
ABS plastic has the capabilities to be laser engraved or laser marked using a high contrast laser beam. ABS plastic engraving is ideal for adding numerous types of content to ABS plastic parts and accessories. Non-contact laser marking is very fast as well as abrasion, heat and acid resistant, and many different plastics can be marked or engraved with a laser. Even extremely small ABS plastic parts can benefit from the laser engrave ABS plastic process.
So seems it’s a NOoooo with CO2 laser, (like those referenced on the atxhackerpace and the GF) but OK with the special type of laser for marking!
