Woah, in the future you could probably do online shopping with this shit. You can buy something and it will print in front of you.

Actually, this kind of 3D printer was just the beginning. The most amazing is the BioPrint, that will in the near future "print" live tissues, plants, animals, human organs... amazing! For selling products, it will be even more crazy. If we can get one of thouse at home, you pick your shoes and print it from your own printer.

That's cool and creepy at the same time

I have printed things in this kind of machines, and i love this technology!

I wonder how the scanner saw how deep the moving part was embedded into the wrench

The post-production team of this video has serious ADD.

Continued comment: If you looks at around 7:46 you can also see that the wrench is quite a bit different from the original wrench. This means that they probably just scanned the original wrench and modeled a wrench with same dimensions from that scanned 3D object.

As someone who works with 3D I can reveal that they didn't just scan it and print that 3D object. Else it wouldn't have been in multiple parts. They either reconstructed it completely by modelling a wrench after/from the scanned 3D object, or reconstructed only moving parts and edited them into the scanned 3D object (which still takes some time).

Unless the scanner was magically able to look into the insides of the wrench, but I really doubt that it works as an x-ray too.

does this scare anyone else or is it just me?

I draw the line at printed food

That is a good idea ;)
