3D Printing

I always loved the idea of 3D printing. You would create a 3D complex object on your computer - something in the forms of an action figure or a monster, and then just print it out as you would print out a letter on a regular printer. You could easily create a custom army of figures for your children to play with.

Fortunately, that's not all there is to it, because you can print out almost any shape you can imagine, for instance this 3D printed bicycle on the left. It was made by the EADS, the European aerospace and defence group out of nylon powder which is, according to EADS strong enough to replace steel or aluminium and requires no conventional maintenance or assembly.

Imagine you are riding a bike down the street and suddenly, it breaks. What do you do? Well, you walk to the nearest printer, plug in the USB and there you go, another bike (probably not that easy, but the future is coming).
