The i3 Duplicator comes with a pre-assembled steel frame for strength and rigidity. It also includes the MK10 single extruder, Heated bed and the electronics are housed in a stamped steel case for added protection. Note that he duplicator comes in three parts, two of which have to be bolted together, due to the way it is packaged.

Given the versatility of the i3 Duplicator it can also use lots of different speciality 3d printer filaments. Dependent upon the filament some modifications may need to be made to the extruder, but for the large part it can print anything that falls within its specifications.
