This was printed on my Ultimaker 2 using Black ABS until a certain height then changing to RED ABS and finishing the print off to the final height. Just to add, I had to make the beam support holes slightly bigger as ABS seemed to expand more then I hoped so if you print this in PLA then you might want to scale the beam up slightly in the Y axis (or X depending which way round you print them).
