Can anyone point me to a supplier in the US ?
I can find it in UK, via ebay, but no sign of it in USA, so I may have to bring some back with me.

Unless Iām mistaken, their 0.040" acrylic is extruded, not cast.
The cast range seems to be traded as āluciteā rather than āplexiglassā, but is only available down to 1/8".
Please correct me if Iām wrong, as the price structure is good.

Youāre probably right. I had two tabs open and probably grabbed the wrong one. Iāll look to see if I can find the other again
Iām now contemplating casting small pieces of my own from a suitable clear casting resin.
Does anyone have any experience of this they would care to share ? In particular US suppliers of resin, possibly UV curing.
Looking to produce pieces about 1" x 6" x thin !
Thatās brilliant if it works. Custom colors anyone?
But those are usually epoxy, which as I understand is not recommended in your laser. I believe you can also get polyester resins but they usually cure white, not clear. If thereās a clear curing polyester, Iād like to know of it.
If you could live with 1/16th inch (1.59mm), professionalplastics.com has it in cast. Itās pricey though. $132 for a full sheet 48āx72ā.
Is this what youāre looking for?

Thanks! That might be laserable.

If I managed to cast that as a 1mm sheet, that would make a 12"x20" work out at ~ $5.60, if I were to buy a quart, to get the free postage.
Mmm, food for thought.
Thanks Arnold.
EDIT though Iām still more attracted to the idea of uv catalysing, I must admit.

Looks like fun stuff to try! Keep us posted on your testing.
I wont be reunited with Glowfinger till the beginning of September, unfortunately, but that does give me lots of thinking time !
