what is 3d scanning exactly?

Is the 3D scanning new revolutionary invention that can change the world?
Can this have similar impact as printing or photography?
Or is it just much a do about nothing?

its only a revolutonary scan machine, 3D full color and screen shot with great sensors, but is effective. It creates a kind of virtual reality.

Do you have any real working samples to show us how real this is?
So far no one seems to be able to produce a real working sample!

Image and the color is more natural, not artificial as others, but obviously we need to show samples and pics.

Romek, I checked out the 1st URL and it is a bad 3D rendition of a Farm House!
And the others are not much better!
I mean we have had 3D Software for along time! So what is the point of a 3D Scanner vs a 3D Software like Autodesk Softimage?

Hi , yes you can create much better rendering in software. But this house was not rendered- this are model of house how it look. If this will be created by great artist or centurys years old - you want to show it how it look . How much work need someone to create exactly same model with all details in cad? And every detail with exact dimensions?

Romek, great samples 3D scanned, especially the following link: http://3denterprise.co.uk/3d-presentation/

A 3d scanner is a device that is used to scan real world 3-dimensional objects. It collects data on the object’s shape, size, contour, and in some cases color. The file that is created from the scan is used to create a 3 dimensional model of the scanned object that can be reproduced by a 3D printer. Common file formats for 3D scanning are STL and VRML as well as OBJ and PLY. Many 3d scanner manufacturers have their own proprietary format.

But the question is is it an actually real product or just a "Pie in the Sky" Hype?
Much as AI was Hyped to be so many times, or Self Driving Cars, etc. etc.

And let me that add that we have had Computer driven Cutting and Milling machines for Years, and they are real. But a 3D printer that can create a complex object is a stuff of science fiction and not reality, I am afraid.

Here's a couple:
http://www.geomagic.com/en/products/capture/overview/
http://www.3dsystems.com/shop/sense

Probably too pricey for the novice or hobbyist, but they scan in 3D.

But the above products produce childish at best products!

But to be sure, are you referring to 3D Scanners, which will Scan a real world object to its 3D code & images, or are you referring to a 3D Printer?
In any case they both produce results that are far from useful, but much more so in case of 3D Printers.

Computer Numerical Controlled (CNC) machines exist for few years - probably from around 1990. Some of them create model by adding material (3D printers) when other remove materials( CNC routers , milling machines ).
Way how it was controlled was basic and complicated at the same time.
Operator write code to move machine from one point to second point.
Operator must to known parameters of tool and material.
Great way to create geometrical objects.

3d scan create 3 dimensional model in computer.
This model can be transform for code for CNC machine.
This way what you 3D scan - you can create on CNC.
Mechanical or organic part. In attached links was hobby scanners.
Have look at www.3DEnterprise.co.uk how precise and accurate 3D scanners they have. Think 0,03mm resolution and 0.09 volumetric accuracy is enought for most even demanding projects. And CNC machines can turn it back to real world.

Romek, but what are some real World examples of 3D Scanning at work?
And I am not talking about only making 3D figures for Movies and CGI. But what are some other real World implementation of this service? Mind you not application, but real world implementation? Because if this really works in real World, I would be a buyer.

Hi , could you tell me industry? I will tell you implementation- ok?
Chose any ... Maybe not accountancy - in finance or accountancy not much can be done by 3D scanning. But industry as aviation , whole engineering , medicine , architecture , archeology , research , investigation, oil and gas , inventors , designers , hobby models- or something other. Beauty of 3D scanning is - can be used nearly everywhere and write about everything is too long.or chose few industrys if you like.

One of most ambitious projects is to 3D scan - aeroplanes.
Each of them need to be inspected briefly before each flight.
Usually someone look around for any visible defects plus maintenance plan.
3D scanned model can be compared - scan before and scan after. Than colour picture as map showing diferences and distance. Are already used to compare CAD drawings to created products. Wind turbine blades are checked that way already. To scan whole aeroplane will improve safety and time.

3D scanners can select rubbish. By 3D scanning objects can identify some of them . David-3D SDK kit give this oportunity. Can compare scanned object to database . Depend of comparison results - object can be removed from line.
Used also for quality control of produced parts by cnc machinning , casting , moulding etc. This huge tyres for huge machines are also 3D scanned during refurbishment process. That new layers of rubber are applied more efectively.

Another interesting example. Car from 1908 have brocken engine body.
3D scanned than reverse enginered to CAD.
In software all worn and destructed parts was draw again.
Than 3D printed from casting sand and casted . Machined , asembled and car with new engine back to life. Next - unique Aston Martin from James Bond movie. In Germany was 3copy of it 3D printed and used for destruction scenes.

Another use of 3D scanners - nearly all car manufactures use it to check that car leaving manufacture comply with standard. Another -http://3denterprise.co.uk/custom-car/ - bottom of screen - pictures of a car scanned and measured. You can see how easy to make linear and geodesic measurement . Any detail to any detail . This way racing car symetry was confirmed.

Orthopedic use of 3D scanners to scan parts of human bodys. From helmets to child head disproportion to scan and create protetics. Plastic surgery when patient will se himself/herself before surgery how will look after. Sport cloths and gears which must to be exact and accurate. Stomatological protetics . Or thousand year old human bones -3D scanned for documentation and research. 3D model can be viewed online in details also measured , cross section cut, volume and cross area calculated.

So what is your industry? So can offer you 3D scanner or 3D scanning services?
Think just the way you can view 3D scanned object is revolutionary.
Museal artifact you can see from any side , zoom in to see any detail. Measure , compare and if necesary 3D print it. Museal or art also as other science and research projects will accelerate. Imagine bones finded in Chile. Within seconds hundreds of researchers around world can see , measure have printed copy , share knowledge and opinions.

Hum! Sounds fishy if you ask me. I mean love the idea of New technology and 3D Scanning sounds sexy, but it seems like not so useful.
Is it possible to see a demo of this product?
And what is the cost to buy a unit?
And what about renting a Scan?

The revolutionary impact of 3D printing is likely to invade all industries. Building will be printed. Nick nacks need not be bought they would be bought digitally downloaded and printed out rather than sent via the postal services. A trully disruptive technology.

3D Scanning, methods for digitizing three dimensional objects so that the may be rendered either on screen, virtual reality or via 3D printing.

Oh really!
It is jut lots of Hype like AI was in 1990s and from which came nothing more extraordinary than good ol fashion Software.
3D Printing is one of the biggest SCAMs in history of Man. I mean if an object is a simple object with 2 or 3 components of the same material, then a 3D printer, aka Cutting Machine can do an excellent Job in mass producing it. Otherwise it is a Hype.
