The prototyping of these swords has been limited to the lightsword model because rapid prototyping of foam is not really possible. We were able to custom "3D print" the plastic handles, but the complex blade shape of the medieval version, while easy in production, is difficult to achieve in the prototype stage. So all we can offer for now is drawings of what that sword type will look like.
The core construction is the same for all versions. We will apply a different "skin" on top of the core design for each different model. We will re-use the engineering of the core construction and all of the electronics and software. We have carefully built the core to accommodate both designs.
The foam that we are using for these prototypes are essentially pool noodles and are NOT the same foam quality that we will use in production. The pool noodles look the best for the pictures and video, but are too stiff for fun sword play. We will experiment with the proper foam formula on the way to production. Joe is going to take quite the beating!
We will work to demonstrate the illuminated blade in the next week or so. Our 3rd generation prototype had an illuminated blade--we know how to do it. The problem was once again the limitation of foam supplies during prototyping. We have some ideas of how to get around this in the short term. We can't wait to film those. It's always fun to film an illuminated blade!
