You gonna eat that?
Why not print a tube pattern on a flat sheet of metal, fold it up and glue / rivet it together? With our method, frames can be “printed” at a local shop and assembled by anyone who can glue and operate a rivet gun. Also, our technique skips any welding that can weaken the the frame material by creating heat affected regions at the joints. Heat affected regions soften the material near welded joints.

Something I realized in the video, it shows the bike being carried/ walked more than ridden...

I'm an engineer so I realize this, but welding and brazing are not as sensitive to post-assembly maintenance and environmental conditions.

Actually, glued CAN have better integrity than welding. Just ask Lotus. The lotus Elise is glued together with a glue that chemically bonds at around 700f and the bonding IS stronger than steel welds.
Come to think of it, wish we could use that stuff for making bike frames.

A friend (and fellow engineer) and I were talking about using 3M industrial epoxy to build a lugged bike--given adequate preparation, it's certainly doable. Hell, the early carbon bikes were bonded together in aluminum lugs...though that didn't always work out.

If the idea was any good, they could attract venture capital rather than asking for donations on the internet.

One could say that about any idea on kickstarter.

That's not really relevant, though. The engineers at Lotus know what they're doing...these people clearly do not. In fact, their entire premise for why welding is weak is just plain wrong.

Problem solved.
