Hi, first of all welcome 
Is the material you want to engrave see-through or transparent? Because I know that is very hard to laser cut with diodes. Maybe a CO2 laser will do better?

I hope your budget is $10,000 to $100,000
May be easier / cheaper to print the labels
PET very high temp and it melts with nasty smell
Plastic --- type of plastic very important --- can't help if you just say "plastic"

Hey guys, just a short update on the lasercutter:
[youtu.be]
I have created a working air filter now, when I cut paper all the smoke and smell gets absorbed! When I breathe the air coming directly from the filterbox, there is no smell, no smoke, no irritation of airways. Of course, I am not going to just huff up on the exhaust haha, I just wanted to know if it really absorbed anything and apparently it does very well.
The box that is below the laser sucks away the smoke directly where it's coming from; the area that is being cut with the laser. This has two advantages:
First is that the smoke obviously doesn't travel from the machine, it is immediately absorbed into the filter system. The openings that suck away the smoke are very close to the cutting surface to make sure all the air travels into the intake.
Second is that the smoke doesn't get in the way of the laser's beam, so the beam hits the surface without being obscured by smoke. Still of course there will be a little bit of smoke in the way since the air intake creates a little 'whirl' where the smoke swirls around in the air directly in the path of the laser beam. I could change the shape of the intake to minimize this effect, but it already removed around 90% of the smoke that was in between the laser diode and the cutting surface.
When cutting paper, there is no smell at all to be detected in my living room, I have used high quality superactivated carbon preparation, they are manufactured bits with high porous surfaces and absorb everything you can imagine. Underneath the filterbox is the suction device, it is an axial fan that sucks the air through, and directly against the axial fan I have placed a radial fan. So the axial fan blows into the hole of the radial fan. These two fan types together create a massive suction power, way more suction when compared to just two axial fans on top of each other.
The intake is a clickable system that I can slide onto the bottom of the X-carriage, there is very little distance between the cutting surface, if I want to cut materials that are thicker I have a second intake that has less height. It will suck less air out, but allows for higher objects to be cut, honestly I don't see myself cutting thick materials, I will just send those to a professional cutting company anyway.
Will keep on playing!
Oh and the reason why I use multiple silicone tubes is because the larger diameter silicon tubing gets too stiff, so instead of increasing diameter, I figured it would be best to just use multiple tubes of silicone. The silicone flexes enough as not to obstruct any movement of the X-carriage.
Meanwhile I've been cutting stencils for my parents (who are artists) and I've been making miniature furniture in wood veneer for my academic research (oak, birch and mahogany).
One small piece of news: I just read now (article published 20 minutes ago) that one of the inventors of the laser Charles Hard Townes, has died today.
