We have seen the increasing popularity of film companies using 3D printers to make movie props. In fact, some Cosplay players are also using 3D printing to create their favorite anime and game character props. Now, another gamer, Farell Rozan, based on his favorite action adventure game "Assassin's Creed IV: Black Flag" as a model, has produced a very interesting prop - Assassin's Creed blade, which is actually the very popular weapon "Xianjian" in our Chinese martial arts novels.

Rozan recently bought a flash cast Creator 3D printer and couldn't wait to create this long-awaited weapon prop as soon as he bought it.

"Assassin's Creed blade is actually my first big 3D printing project. I've always wanted to try to print out a pattern with mechanical moving parts." Rozan explained. "Since this is my first (project), I want to make things that are easy to use, such as just pulling the trigger. But grabbing a stick requires a lot of mechanical parts, which is not a good choice for beginners. And I've been playing Assassin's Creed IV: Black Flag, and I thought the sneak sword was the best choice because I like this weapon very much."

After making the decision, Rozan searched the Internet for the perfect 3D model of the Shoujian. But he found that the 3D models he found were all large and often needed a very thick handle to install a retractable sword blade inside. Finally, Rozan decided to design it himself and then 3D printed it out.

"Using Google's Sketchup software, I designed a model of a sleeve sword pop-up device using rubber bands," Rozan said. "Then the swing fixtures and some connectors after the pop-up to combine the entire sleeve sword together."

As a newbie who just learned to use 3D printing, Rozan encountered difficulties in correcting his 3D printer and had to revisit several aspects of his design. Among them, the 3D model he designed was too tight and did not leave any gaps for possible errors. In addition, he also had trouble determining the appropriate print fill rate for the Hunjian, because he was using ABS material, and he wanted to find the correct fill rate to avoid bending, etc. Finally, after carefully studying 3D modeling and printing a large number of experimental products, his 4th edition design finally met his own requirements.

Rozan summarizes the experience he learned from the whole process:

"Simplify the components as much as possible, allowing some minor defects or deviations to be printed. Sometimes it can be post-processed after the printing is completed, without all the modifications being done on the computer. Calibration of 3D printers is the key. There are many times, I think the problems that arise from the 3D model errors in the design, but it turns out that this is due to the problem of not getting the correct calibration of 3D printers. And it is also important to set the correct model orientation when you print parts with higher strength requirements."

All in all, Rozan spent about 12 hours in total, printing all the parts using a flash cast Creator 3D printer, and then another four hours to post-process. This sneaker has a total of 42 parts, including non-3D printed rubber bands and wristbands.
