3D scanners .... wow !
Last night I was visiting Alessanro Ranellecci's lab (unterwelt) and the showed me their affordable 3D scanner ... (less than 100 dollars) ...
It's a Microsoft Kinect ... the result are impressive they use it to make 3d portraits to be printed on a 3d printer ... here you find a base for more information: http://www.virtumake.com/forum/viewtopic.php?f=10&t=250 http://skanect.manctl.com/ |

Interesting. Would like to see more on this. I have tinkered with David before but like to see a more affordable solution.

Pete,
I'm going to test one this week ... I'll keep you informed |

Cool results (if it works like the video )

I have seen the results personally, both the scanning and 3d printing ... very good. I hope to test a kinect with the mechmate as soon I have it working on my pc :-) ... I miss the usb adapter at the moment ...

cool, let us know ! The other day I had a business client with exactly such a problem. We could not draw the shap in CAD for him, as he needed an excact copy of something, which we then had to adapt. It also did not fit under a machine for probing either. Some inquires showed that companies capable of 3d scanning charge big bucks for turning an object into a 3d CAD file, so it could be a worthwhile thing if you can offer that reliable and affordably to clients and have a CNC or 3d printer to produce the object.

Yes Fox, that's exacly what I'm looking for ... it would complete our capacity ....
the precision you should expect is around 1mm, not so bad ... I know there is a short range similar sensor that is even better .... unfortunately it's not available anymore at the moment (apple bought the company) it's called Carmine 1.09 ... |

Auch... 1 mm is too course, unless for larger statues or something.
0,1 mm would be more usuable as a resolution, but that's probably why the commercial versions are more expensive. |

with a 170cm tall person, 1mm resolution is good. but for the price, don't u think 0.1mm is asking too much?

I would think that as technology evolves the price would come down on the older stuff. This however does not seem to be the case yet with 3D technologies. I have had good results with David with being able to get the texture from an orange and a couple of ornaments. But I have not put much time or effort in building up the required steppers to get better control environment.

Fox, I think I have difficulties on explaining well ... but the sistem resolved the hairs of the girl better than 30k $ scanners ... I intended 1 mm error not resolution ... But things have to be tested better and I can't tell much as I did not nor I am an epert ... but I am very confident.
My idea is to have something that can give me a good base for "replicate" object,ornaments or use strange pieces of wood (maybe just irregular surfaces). And as Ken said ... 1mm on a 1.7 meters is not bad at all. |

I am still interested in your trials. Please keep us informed.

Ok I see, still interested as well. For my sample case I spoke about 1 mm deviation would not have been acceptable hence my response. Not intended to demotivate you or such !

Hey Fox, don't worry ! just testing understandig and sharing

Fox, if you need 0.01mm resolution try structured light scanning
However, new projectors are more expensive then a Kinect sensor, I'm actually surprised to find out. |

SLS has some disadvantages too. I have not found a 100% system yet that will handle everything. That is why I am glad new approaches are being made because it should help drive the price down on these scanners in order to stay competitive.

Ros, those are common examples, but they limit your scanning to the heigth of your gantry / bed to center of your lathe. Ideally you would want a handheld scanner, with good accuracy to be flexible with larger 3d objects to be scanned.
Another note a crazy DIY option for large objects: http://www.instructables.com/id/Mult...anner/?lang=pt |

3D scanners and printers are fantastic, I wish I have one of these...
