3D Printer

I guess, the video below has become popular for the last few months. By printing we normally understand printing image on a paper. But we probably can generalize for higher dimension.  The video demonstrates, by scanning a wrench, the printer can really replicate another wrench and we can choose a different color for the wrench too.

The technology  apparently looks very simple. Use nylon powder as printing material and make 3D blocks by stacking 2D layers.

The next BBC video goes for a bigger challenge. It’s not a small wrench, it’s real, ride-worthy bike.

Isn’t it something truly amazing ?
