Metal bone

bone-like metal composite structure

I was born to do this.

After 40 years of teaching, I finally made it - a metal bone.

Most importantly - the cost of such technology is a few bucks*...

* Literally - a few bucks.
The method is so brazenly simple and effective that children can use it.
Most homes have all the things you need to do this...

Mars will be crowded 😎

what am i looking at? not clear the point.

  Are you sure? yes | no

You can create metal composites of any topology and internal structure. In easy and cheap way.

What sort of density compared to solid metal? Can you control the wall thickness? Can the inside foam be any size, or only a few mm like in the pictures? Does it only work in flat pieces, or could you make tubes with two thin walls separated by a layer of foam to increase stiffness, or even mold it in more complex/3D printed shapes? Does it only work in brass, or could you use aluminum?

Thank you for these questions!

One of the samples had a density 1.2g/cm3, so like a rubber. But! I can't bend it in my hands...

In general - you can change all parameters of this structure as you like. Size doesn't matter. A 1cm or 1m item will be created at the same time.
You can use almost all metals, in any configuration, alloys etc.

Of course, it is possible to automate the process and use solutions known in 3D printing. However, I am working on a much more efficient method. The object will be created freely in space, without mechanical contact with the robot arm or the printer head.

Sounds very useful! Are you planning to open source, patent, or take it to the grave?
