Leapfrog creatr:

specs: The creatr has an immensely large build size at 23 X 27 X 20 cm, this is significantly larger than almost all desktop 3D printers. The printer also allows you to print in 3 different materials, PLA, ABS, and PVA. The fact that it is able to print in PVA (which is water soluble) means that a dual extruder 3D printer like the leapfrog creatr can print the model with one extruder printing with PLA or ABS, and then the second extruder printer
