Katanas are traditionally a Japanese curved single edge blade between 60–73 cm. This is one was 3d printed in 2 pieces on my custom XXL Rostock Max w/ some spare filament. Its blade length is ~72cm and the total length is around 1m. This was a fun project and about 2 days worth of printing. The final weight of the katana was ~326g. It would undoubtedly break if struck strongly against something but it's surprisingly sturdy. I haven't seen another full size 3d printed Katana yet so I'd like to think this is the first worldwide.
Good luck printing!
