A long-duration print is a challenging test for a 3D printer.
We printed the T-Rex skull by Makerbot in massive size on the new Raise3D Pro3 Plus. It weighs over 1.4kg and took over 158 hours to print! That equates 6,6 days!

What is important when planning such a long print? Why is the Raise3D Pro3 well suited for printing this in PLA?
