3D scanning thread

[SeaBorneScanner]

I'd recommend David SLS kit.
I have scanned objects as small as a fly and as large as a human being with amazing results.

The whole reason I bought this scanner and wanting to get a B9C is to make custom jewelry with people's face on it.

SeaBourneScanner, could you post some finished work (casting photos or finished jewelry) I also have been wanting to do my jewelry with the feature offered to my clients. Checked the David web site and the kit complete is 1999 Euros I think. Is this what u are using.

Hey Robert,
Unfortunately since I can't afford a B9C so I don't have any work to show, I only got the scanner at this stage, which was 2000 Euros like you mentioned. They did gave me 10% off because I'm a student and I used the scanner for a research project involving custom anatomical prosthetics for people who had gone through head and neck tumor removals.

That scanner is relatively simple to use and set up, fairly mobile, and gives wonderful results.
The only problem with scanning faces is that the light is quite bright from the projector and it's blinding people esp. with blue and green eyes, and also that it's hard for some people to stay still while it's scanning (about 10-15 seconds per scan, and usually about 6 scans with 60 degrees intervals + one from the top for a complete model), so many people solved this by building some head support.

Maybe I can make something and send it to shapeways for printing and casting, then I can show you pictures.

Opaque contact lenses?

I had scanned a head by DAVID with structured light, (post Sept 27th):

.... mounted it on the upper body of Iron Man and printed it (post July 11th):

By the way: The light of the projector can be dimmed in DAVID with a slider. So it's possible to let the eyes open.
And yes, a head rest should be used. The time for one single scan can be reduced to about 3 sec, it depends on the camera.

A new approach to 3D scanning. What do you think?

I think that photo based scanners have existed before. I haven't really read this too deeply but it doesn't seem novel. In fact, hasn't auto desk incorporated that into their latest 123d suite?

Disclaimer, i rep these scanners... but 3rivers 3d scanners can scan small objects like jewelry with excellent results. In fact they recently inproved their macro scanning capabilities with a new unit.

Here are a few samples of small scans performed with their standard unit. http://www.3rivers3d.com/gallery6.html

I can try to get some new images as well. Seems to me that i have some images of circuit scans somewhere...

By the way, I have always been a fan of the davidscanners as others have suggested.

Behold, what price for the scanner. Went to site, no jewelry scans.

[behold3d]

i will work on getting you some jewelry scans. The scanners run from 15 -18 thous. That price includes an automatic turntable and all the accessories. It is the only scanner that also runs on Mac. Their is also an automatic merging and stitching capability that i believe the studio has just recently completed.

I'm waiting for my crowd funded Matterform 3d scanner. Should have as soon as they get them cross the big pond. Got in at 500,00, Last batch. Have already upgraded hardware and scan quality while getting into final production. Have some sample scans u can download and drive around.

Has turntable and all that built in and folds up for transport. Don't know if it will do what i need, but want to give it a spin. Has all software included. Take a look at the specs and tell me what u think.

[behold3d]

initially what i think is that it will not be appropriate for scanning jewelry. (That is your intended use correct?)Let me compare the 3 river scanner to this one if I may. You can really use any scanner's specifications but I caution you that there is no standardized vocabulary.

The Matterform scanner says it can " Capture details as small as 0.43mm Capture size within ±0.25mm" Which is very confusing. I look at that and say then they must have the laser diameter colliminated to .25mm and can scan at a resolution of .43mm.

The 3rivers 3d's macro scanner has a resolution of 80 microns which is .08mm. This is more than 5 times the resolution.

I know that this next fact often times means very little to some but time is money. It is also the downfall of nextengine scanners too.
Their scan takes 10 minutes. They do not say that it takes 10 minutes for full 360 deg or a single view. That seems extremely long.
The 3rivers 3d scanner takes 5 sec for a single view. Depending on the number of views you select, the 3rivers 3d scanner takes approximately 2 minutes for a complete 360 deg scan.

Let me know if you have any other questions.

[behold3d]

I would also caution against scanners that have their own process of producing water tight meshes. Usually a poisson reconstruction type of function (which this would most certainly be) blobs out scan data and adds geometry where there are shadows (called occlusion)

[Robert Howle]

Did u look at the scanned sample files on the web site. I don't intend to scan jewelry. I will be scanning items to add as jewelry elements. Maybe a toy tiger or leaf or shell, etc. to scale down and use as decorative elements. Not sure just got it to play with.

Robert

[behold3d]

Yes, they look like what I would expect from a scanner with that resolution and that processing technique.

I've successfully been scanning jewelry using a 3Shape scanner. They are primarily used in the dental industry but have adapted it for metrology/QC purposes. >15 micron accuracy, has been working for me, pricey though!! $30k... :(

I'm talking 500 dollars stuff. Will take my chances. Thanks. Might end up with a 500 dollar door stop, but that's ok. Crowd funded machine. We'll see.

Scanner for your smart phone coming soon?

any recommended urls/sites for 3D scanning 101, Fundamentals of 3D scanning? overview then details of different technologies and products?
