Created in Zbrush and checked in Netfabb. It is watertight and ready for printing. It consists of two parts: the body and the blade. Assembling them together is very straightforward and should not cause any problems. Model of the body is 2 Mil polygons (triangles) and the blade is 200 K polys.
There is one overhang that might need more attention - the right arm. I have tested it on a FDM printer with 20 degrees support and it printed nicely both in 0.1mm and 0.15 mm layer height (the model was printed 16 cm tall). On that basis I decided not to make it a separate object. The detail on th armor is very intricate and it can fully utilize capabilities of even most precise SLA / DLP printers.
