Formaldehyde-free MDF source in US?
We have had some solid success with our fun new laser cutter toy recently, and we would like to move on to cutting MDF. Thing is, burning MDF is supposed to be bad for you due to the formaldehyde content, right? So we've been trying to find 1/8" (3mm) formaldehyde-free MDF with no success. I can find it in 1/4" thickness, but that's really not what we're after.
Does anyone have a source for 1/8" or 3mm formaldehyde-free MDF in the US? Preferably standard sheet stock size 4'x8'.
