Rapid Prototyped Bali

I've mentioned before (briefly) about trying to get a balisong made from a rapid prototype machine owned by MSOE (milwaukee school of engineering). For those of you out there who may not be familiar with a RPM, it's essentially a 3 dimensial printer of sorts. It creates a solid object by laying down layer after layer of whatever material you want to use, all from a CAD drawing. It uses a laser and is acurate up to 1/20,000 of an inch (depending on material). It allows otherwise "impossible" objects to be made, like a solid ball inside of a solid sphere. Instead of the blade being attached to the handles with a seperate pin, I could make the pin and handles one solid piece and create a blade around it. It wouldn't hold a great edge, but it WOULD be great for manipulating (and "printing" off as many copies as I wanted :D) This project may end up kuputz if I find the cost to be to high :(, but if not, I may have an interesting bali on my hands.

How should I figure the handle to blade ratio to get a balanced feel. Figuring that the blade and handles will be the same material, what kind of length and weight should I expect to work best? What's an acceptable ratio?

I have asked this in the past...

Just what is the "perfect" baliong handle to blade weight ratio?

All I got was "personal preference"

I say, check the balance points of the balis you have, open and closed, catagorize all the information, Use statistical method to find the mean point of balance as compared to total length, (I think it's called a CHI test), and then do what you feel is right, or at least what looks cool.:D
 
I thought those machines could only make things out of a certain substance like epoxy or resin. don't they use a laser to harden layers of liquid?
 
Belstain - Now they can RP anything out of 420 steel. But I would still have the option to have one made out of hard plastic or nylon, just for something "publicly kosher" to flip around.
 
The technology you menitoned is way out of range for me..., but it sounds like a fascinating project...keep us updated!!
