Struggling to get spare parts?

How does that scanner scan parts of the component or assembly that are hidden? Like the worm gear on that spanner, how did that scanner scan the part of the gear inside the hole so that the "printer" knew what it looked like?
I suspect they went in and edited out any connections between the screw thread/moving parts and the rest of the spanner after it was scanned.The same scanning technology is being used by the police to map out some car accidents. Obviously it's a tad bigger and rather than rotate the object you rotate the scanner.

think i see this on the TV the other night they was investigating an Audi S3 accident,very clever stuff.Munter said:

Last week I had a broken tooth. She stuck a tiny gadget in my mouth that turned out to be a 3D camera/scanner. It scanned the hole she had drilled out then a tiny milling machine next to her PC created a crown out of a block of ceramic which she then glued into the hole. Driling to filling and back out the door in under an hour with a perfect fitting crown.
Shes hot too.

Was this broadcast on April 1st ??? I think someones fooled you all !! 
*cough* http://www.dimensionprinting.com/ And we know the technology behind the scanner works. The basic science behind it has been used to measure the distance to the moon since Apollo 14. It's all perfectly possible. Assuming as above they did some thinking to make the spanner. Scan all parts then reassemble sounds better than my idea!It's not cheap! But it is all possible.

And produce moving parts ???
Strange that the clip is not longer accessible !!!
What do you mean by moving parts? It can reproduce any 3D item you give it a model for (with obvious size restrictions). So if they gave it models for all the parts of a spanner (models presumably created by the scanner). It could print all the parts and they could put it together by hand.Strange that the clip is not longer accessible !!!

I would think the model would be accurate to 0.5mm or so. The printer similar. And it's unlikely the spanner needs to be that accurate to work.
It is amazing. And it boggles the mind. But I'm sure it's real.
. Yeah not so sure about that. https://www.nextengine.com/indexSecure.htm

apart from the 'assembled' adjustable wrench and the complete steam valve all of the other aspects are well known in manufacturing with the use of stereolithography. We use it to produce turbine blade models for stress pattern testing or proving a component before it is cast, forged or cut from metal on a CNC machine.
The above website looks genuine otherwise it is a major and costly hoax that Jay Leno has signed on to.

Seen this tech working Keith, look at this site.

We have that exact machine at college that we can make CAD prototypes in (the dimension 'printer' that is).
It can produce parts that move straight out of the machine, but it takes a few goes to get the clearances right. On the CAD software you have to adjust all of the clearances so they are quite large and because it is made from drops on plastic that are basically piled on top of each other to make the shapes, the overall finish is pretty poor and the clearances are so huge that a complete assembly is pretty slack.
But it definately can be done!

OK , I'm convinced now. Spent the day playing golf, talking to my aerospace friends. They tell me they "grow" parts in solutions with a pair of lasers firing into the liquid...it's all to mind boggling for me. Thinking about the soluble structures, I can now understand what they're getting at with "sterolithography printers" or whatever...they build two structures one of plastic and one with another solid, but one that is washed away after, thereby creating a moving part.
It's all a long way from when I was responsible for installing CATIA for the first time 20 years ago, and I thought 3-D animated computer models were cool and we put std. European Pilots in Eurofighter... Just goes to show what an old fart I've become .... back to polishing the Tivs.....
Good news is they still use CATIA ...20 years later... (Version 5...Bloody Frenchies!!)
You know it's a pity there's not a "Tomorrows World" any more.... even without Raymond Baxter... Any TV schedulers out there....time for a come back !!!
