Does anyone know what Lego bricks are made from? I was wanting to cut some for a Logo, but was concerned they might be PVC. I have a Trotec Atmos Duo extractor rigged up to my Speedy 300. Anyone else cut them before? Am I ok cutting them?

I think they are ABS. If so, you should be okay.

Real name Steve but that name was taken on the forum. Used Middle name. Call me Steve or Scott, doesn't matter.
Yup they are ABS, I cut quite a few of them for different companies.

You did what !
Lego is a PVC free company due to child safety concerns. I also found this that might help you...
Most parts are indeed ABS as it's a very sturdy plastic, but sometimes it's not suitable, or downright impossible to use. I've seen a presentation on quality issues given by a LEGO employee in LEGOworld a few years back, and as far as I remember there were between 10 and 20 sorts of plastic in use. The ones I remember are:
- ABS (acrylonitrile butadiene styrene) for most regular bricks
- PC (polycarbonate) for transparent bricks, as ABS can't be made transparent. Polycarbonate parts on the other hand have too much friction when in contact with other polycarbonate parts, making them extremely hard to disassemble. LEGO designers are forbidden to have some PC parts put together in models.
- Rubber for tires and rubbery things - that's kinda obvious
- A less sturdy plastic (can't remember the name) for parts which are more subject to being bent, for example studless technic beams.
And the list goes on. I know the presentation hadn't been made public, but some people took pictures, so if I ever find it back I'll add a link.

I have cut ABS until I read that laser cut ABS off gases Cyanide fumes!!! Taken from
http://wiki.sshchicago.org/wiki/Laser_Cutter
Bananas contain Potassium 40 and are radioactive too, Hydrogen Cyanide in the amounts emitted by cutting Lego bricks is present in *trace* only amounts. You will be exposed to roughly 40 times as much by eating a single apple pip. The smoke / fumes aren't nice but then again neither is Ammonia given off by melamine or Formaldehyde given off by plywood.
Treated with care it is very unlikely to cause any more problems than most other Laserable materials.

You did what !
The take away being, of course, that you should eat Lego bricks rather than Apple Pips.
<grin>

Has anyone tried cutting a lego build plate? I've had a family request to make a lake by cutting out a green plate and filling the hole with a blue one.
