Anyone tried an acrylic/perspex sheet on the bed ?
Was thinking of trying a 4mm sheet on top of the glass, seen it being used succesfully with ABS on youtube.

If you try to print PLA on it, the print will be ruined as PLA actually FUSES to the acrylic at the temps we use.. You will not be able to separate the PLA from the Acrylic.
Thanks for the heads-up on that Carl.
I guess you could use tape on one side for PLA and use the other side for ABS.
I have several sheets of acrylic. I'm willing to try it!
I've ordered a piece to try. Was going to buy a piece of glass but perspex is way cheaper.
Well, I tried a 200x200mm sheet of acrylic (I'm using it on top of the stock glass) and it works fine with ABS. It works with PLA too after lining with kapton tape.
The only downside is that it seems to curl at the edges if you set the bed more than 45°C but it works fine without going higher anyway.
So a cheap alternative to using glass. Now on to try it with hairspray ....... 
The acrylic curls or the print?

Yeah the acrylic. Sorry, should have made that clearer.
Carl, would PLA work with hairspray on acrylic or would it still fuse ?

Can't answer that one, never tried..
I just know there is some sort of reaction between PLA and acrylic at the temps that we use that make the PLA seem to be glues to the acrylic. They might as well be one piece.
Cheers. I may give it a go later. The panel only cost £3 so no big deal if it goes wrong.
It might be a nice way to make a clear bottom on a pla print...
Just to update, haven't tried hairspray yet but securing the plate with bulldogclips has fixed the curling/warping issue so I can now set the bed hotter if I need to.
Must say, It's very handy having a removable plate. So much easier to clean and remove prints from.
Ok, I just had a go with some (very cheap) hairspray on the acrylic sheet and it works REALLY well !
ABS and PLA both really easy to remove and excellent adhesion.
Reckon I'll be using this from now on.
So what bed temp for ABS with acrylic? How about warping on larger prints?
So far, I've tried up to 60°C and it seems fine.
With hairspray, I doubt you'd need to go much higher as ABS and PLA seem to stick very well at that temp.
I tried a print last night that covered about a third of the bed and there was no warping at all.
This is one of the biggest prints I've done so far, covers about 80% of the bed.
Printed with wood-based filament which adhered to the acrylic/hairspray great .....
Beautiful!
Thanks.
Not bad for 0.3mm layer height.
The acrylic is quite thick. The stuff I have is much thinner. Hopefully that won't warp more.
Did you make your z adjustment in the printer settings or with g code?
How many clips?
The panel is 4mm thickness.
I didn't make any z adjustement, I just lowered the bed manually with the adjusters.
I use four 40mm bulldog clips. The one at the far right needs to go in front of the bed adjuster or the nozzle will slam into it.
