The iTopie is a derivative of the very popular Prusa i3, the main purpose of this new machine is to save assembly time, especially for workshops. The second goal is to increase rigidity. 100% MDF structure seems to be the best solution, rigid, cheap, no vibration and if we accept that a 3D printer is a CNC with an extruder, then this machine becomes more self-replicant. Note: The plastic parts of the X and Z axes are compatible with the Prusa i3.
