But the website says these signs are Acrylic, not Lexan...
]]>imagine if you could print (without any separation that would make stray light) a vase then engrave frosted designs in it and sit it on an illumination base (saw a small square base on thingiverse)
]]>polycarbonate is just plexiglass only brand name dif (plastic) may do fine for PLA but I wouldnt use it with ABS for print bed.
Lexan is a brand with a different blend and wont fade, yellow etc plus is more pliable and transfers light similar to plastic fiber optic rod giving off almost neon colors and is used to engrave lettering into and lit by the edge to make letters glow for signs also. some thick versions also used in bullet proof type glass applications and it costs lots more than plain plexiglass. not sure if it takes as much heat to melt as plexiglass though.
Since it is off topic I would love to see a separate topic on engraving lettering into Lexan that light up using side lights.
Sounds as though you have experience doing this and I would love to learn more!!! I could build a very cool enclosure for my SD3 So if you have done this please start a separate topic.

]]>PS1 cases is pure ABS so that was like extruding usual ABS pellets.
Most of the first ABS stuff i printed was from grinded PS1's 
Since then i have saved every piece of plastic from TV's, old printers etc.. to have some to experiment on.
Good ABS came also from old HP printers (pure ABS)
TV cases (new) are mostly PC+ABS.
Pure transparent PC filament (ordered from E3D) is a pain in the ass to print with (E3D V5 hotend). It warps a lot.

Acetone doesn't touch polycarbonate. I still have pieces stuck in an HDPE bottle trying to dissolve (so I could make PC juice), months later.
Even PC-ABS seems to be acetone resistant, though it seems to affect it.
*based on one experience I had with PC-ABS and trying to acetone smooth it.
