A really nice detail on your installation!
I was and am consumed by glowlove. It has changed my life. That may sound shallow, but I had been dazed and confused since a forced retirement after a three-level spine fusion 5 years ago. Now I have something to point myself at. Learning design software, 
and how to sculpt with a concentrated beam of energy.

I can literally feel various forumgoers clenching and then unclenching when they read the title and then get inside and find out you were laying a vinyl decal onto PVC instead of firing coherent light directly at the PVC itself.

Really nice ventilation system dnix1955 and it looks even better with the GF logo. Well done! 
Well, you were half right lol. I clenched at the title and Iâm still a little ferklempt becasue it kinda seems like there was firing coherent light directly at vinyl. (Vinyl = 
) I was trying hard not to be an overbearing forum den mother by asking if it was laser safe vinyl.

My understanding is that âvinylâ decal material is Still PVC and should NEVER! be put in the laser as it still will release toxins that can hurt the laser and you.

Actual vinyl: completely safe.
Based on everything Iâve ever read, vinyl is hazardous and corrosive unless you have a machine specificity set up to handle it. Why are they all wrong?
I think what heâs saying is that itâs not the âVâ in PVC thatâs bad, but the âCâ. Regardless, what is conventionally called âvinylâ is potentially very dangerous. I hope @wesleyjames edits his post to clarify that.

I mean Vinyl letters âGlowforge logoâ on brown PVC pipe.
I suppose âactualâ isnât enough of qualifier to seperate the misuse of a term from what it actually is. 
At that point I say buyer beware. Know what youâre doing as what I said is 100% accurate and true. The material vinyl is perfectly safe. If someone is selling mislabeled material, the responsibility of that is on the label maker.

What is this material âvinylâ? I Everything I know I learned on Wikipedia and they do not list a material called âvinylâ. I am missing something, please enlighten me.

Polyvinyl chloride, also known as poly vinyl or vinyl, commonly abbreviated PVC, is the worldâs third-most widely produced synthetic plastic polymer wikipedia: PVC
In popular usage, âvinylâ refers only to polyvinyl chloride (PVC). wikipedia: Vinyl

I think the way that languages evolve means that âpopular usageâ always eventually wins. I think itâs pretty rare for the it to go the other way. You can still have the technical definition but itâs then only âaccurateâ or âactualâ in the clearly defined context.
There are some words that weâve given precise definitions for specific technical things, but demanding that popular usage conform to the technical definition just isnât going to work.
Happens both ways, a technical term stolen by popular usage or a normal word given a technical definition. Either way, I think the speaker is obligated to acquiesce to the likely interpretation given the either technical or non-technical context.
âworkâ is defined as force times distance for some physics contexts, but insisting that is what it should mean in other contexts or even product advertising is both silly and unlikely to change popular usage.
Similarly, I think âvinylâ left the barn already. Even though it started as a technical term with a precise definition doesnât mean it is any more likely to be taken back from popular usage. So I think for general conversation it is now a general term that includes things that contain chlorine.
