This Plastic Can Repair Itself

And it could someday mean self-healing smartphone screens Forty years ago, plastic surpassed steel as the most widely used material in the world. Sure, the affordable and malleable polymers have brought plenty of convenience to modern life (Tupperware! Teflon! Velcro!) as well as taking on more-v...

Boeing's futuristic technology to 3D print objects while levitating in space [video]

Boeing has patented technology to 3D print objects while levitating in space. Boeing plans to 3D print aircraft parts using this technology. For more details check - http://patentyogi.com/obzxx

Multiple 3D printers are used to simultaneously print various features. The printing material has diamagnetic properties. When super-cooled becomes a super-conductor.

First, a small quantity of the printing material called nugget is ejected into space. By creating magnetic fields, the nugget is held in space by levitating it. Now, further deposition of printing material can be made from any direction in space.

This technique offers many unique advantages.
1. Material can be deposited right beneath the nugget.

This is not possible in conventional 3D printers, which follow a bottoms-up printing technique.

2. Additional magnetic fields are used to rotate the nugget to any orientation. This allows fabrication of more complex features

3. Even acoustic levitation can be used to levitate nugget

4. Simultaneous use of multiple print heads increases the speed of printing objects many fold
