Mine is a FelixPrinter. Some description I made: http://edutechwiki.unige.ch/en/Felix_3D_printerhttp://edutechwiki.unige.ch/en...
Heated Printbed, 0.35mm nozzle, 0.1mm layer resolution, optimized for PLA printing. (but I don't print that precisely, it would take too long)
But I believe that any recent PLA printer could do these, i.e. a somewhat bigger nozzle can do too if the machine can more or less accurately print 0.25mm layers. Older ones (like my RapMan V3.1) can only print DUPLO size, but do that well.
Printing with ABS won't work I think, unless you got a heated chamber. The models with large walls could warp at upper levels. I didn't try.
