Whatever is scanned is replicated exactly in 3D

With nanotechnology we will soon be able to replicate anything that we can think of... diamonds that would take millions of years to naturally develop, gold, water anything.. All down to the molecular level.. even medically the possibilities are endless.. able to regenerate wounds you name it..
Imagine this technology falling in the wrong greedy hands? It's pretty scary to think that humanity has this kind of technology at our fingertips knowing our species is at a very young stage... countries are still at war there is still racism and people fighting about who's religion is right.. We got a lot of work to do!

Thats the difference between a Volkswagen and a Chinese copy car. It looks the same, but only one is solid and can be improved. But the printer is a very nice machine. Why does it have 230V? Does it come from Europe?

That's all cool and amazing, but how did the scanner obtain the shape of the screw which is almost entirely embedded in the wrench? How does the scanner know it should move, not be attached to the rest of it?

Looking closely at (4:26) the 2 items there is a few differences..???
The shape of the end hook is different/the screw in the centre has 3 grooves on the copy but 4 on the original/the movable face on the jaw has a different angle on the original/the recessed part where the writing is has a completely diffent shape on the copy...???
Not calling fake but I think the shape is computer generated NOT a scanned "copy"
p.s. Hasn't this been posted before??? OR IS IT JUST A COPY????

#5 X-ray and ultrawave i would say. We have enought sensor tech nowadays. But the scanner is not the big point..it could even print things you design in a modeling tool like 3D Max or Cinema4D. (But you are right..the scanner looks a big weird..but who knows?)

I'd like to know how the hell it knows what parts are supposed to move and how does it create the moving parts rather than sticking it together with the rest

It's obvious it's not as easy as just scanning an object and printing it, but the printer itself is nonetheless a fantastic piece of work.

Buuuull. Shit.
Maybe it can print some 3D objects. OK? Maaaybe... But those two spanners are different. Very different. Look at 0:10 and then at 3:36 / 3:45 / 3:50 / etc. It's not an exact copy. I don't think it's a copy at all.

...and this funny handheld infra-red "stereo" hair dryer can actually x-ray the inside of the tool? Come on

Really #3? Diamonds, gold all the way down to the *molecular* level? Nanotech to replicate water? It appears that some of us have more work to do than others. You need to put the pipe down and get to the nearest pubic library. I recommend you start with remedial science and work your way up to basic chemistry.

I am an engineer and have to use rapid prototyped parts quite often. Most of you are right, the scanner thing is more for abstract shapes. To get an engineered product like a wrench you need the CAD files to obtain the geometry.
If you can imagine, it sections the part into layers of 0.02mm. The print head has a laser which solidifies the powder layer by layer. To get the screw to rotate in the wrench it would simply leave a small gap around the shaft edges and build the "cage" around it. on completion you remove the powder from the gap and viola the screw can rotate freely.

#10 Totally agree there 2 completely different ones , also Look on there site those 3d scanners look likes a toy , theres no way a hope in hell they just put a wrench down flat like that and are able to get all the dimensions and complex curves right .
There should be a warning on this video "Some steps were skipped to avoid us looking like bull shit artists"

#4 The difference between US and Europe as far as electrical power goes is that US runs 60 Hz while Europe runs 50 Hz. In the US 120/240 , 208,230,277,460,and 480 are all used in differing applications.

can we make copy of black children into white children

The scanner has no idea how the wrench moving parts look *inside* the wrench. Which is why i believe they must have edited the scanned copy to accommodate for that. The scanner can't see the spinners two pins holding it in place so you can spin it. Hence they must have "modified" the scanning copy manually. My point is the scanner wold have no idea how long those pins would be. It sure in hell wouldn't make a guess. Clearly humans help the machine.
It's amazing work however. Really amazing. It's a step up from machines cutting out objects in metal, but not really this complicated.

Awesome, just design your own car, print it and drive it.
next step: instant replicator.

#18, you're right. Like #13 said, the printer needs a 3D model. The scanner helps in obtaining the shape (it's a stereo camera pair). Did you noticed the white dots they put on the tool? The stereo camera needs them to link both images and get the sense of depth.
After that, the user has to make de 3D model, its not an automated task.

QUICK GUYS! PUT THE BENJAMINS IN!
