CJay:
I'm having great fun with my little Flashforge but it's apparently only good for PLA, now as far as I can see thewre aren't any glaring differences between it and the printers that print ABS as well as PLA other than a heated bed, I've also seen claims that people have successfully printed ABS with the finder.

I am wondeirng if it's worth trying ABS in it, is it likely to damage the 'hot end' or is it just likely to be an abject failure if I don't have a heated bed (something that doesn't look impossible to retro fit) or should I just wait til my second 3d printer arrives?

sentry:
Yes, it’s possible to print ABS without a heated bed, but you will likely experience ABS warp, because the bottom of you print will cool at a different temperature than the rest of your print. You will likely also experience that you print will not stick to the bed as easily.

If your hotend can reach temperatures around 240o C then you can use ABS. Remember that changing to PLA afterwards is a pain because you will need to clean the nozzle for ABS.

ABS is becoming less popular now when you have better alternatives filament types such as PETG, which is as strong as ABS, but much easier to print. Still recommend using a heated bed with PETG.

cnering:
Another vote for PETG here.  It's more difficult to start out printing than PLA (you'll be printing a LOT of test cubes to get it right) but once you have the settings dialed in it's great.  Very strong, durable, flexible so it bends instead of breaks, etc.  You just need a hotend that can get to about 245*.  A heated bed is not strictly necessary, but makes things easier.

Once I started printing in PETG I never went back to PLA.  It's just better in every way.

Discotech:
Another vote for PETG similar strength to ABS but a lot easier to work with

Brumby:
I saw some PETG in silver that specified a temperature range of 195-225ºC, which is a pleasant discovery.
