3D Scanning Systems comparison
(OP)
Hi everybody
I hope,I will be able to find some useful comments from you on 3D scanners.
I have been given the assignment by my company to compare 3D Scanning (Digitizing) Systems availible in the market on following points:
Price
Accuracy
The names that i am familiar with are GOM, 3D Scanners, Faro Arms, Minolta, and steinbichler.
I have following questions in mind!
1) Which system is the best in terms of cost, accuracy, time, point cloud data noise, etc.
2) Which sytem is mostly in use in Scanning Service Bureaus?
3) Which system is most versatile in applications, I mean a system that can be used in aerospace, in automotive, in mold & Dies etc.
4)which technology is best (Laser or White light)
5)Any specific comments on following systems:
GOM
3D Scanners
Faro
Minolta
steinbichler
6)Can somebody give me price range idea of following systems manufacturers?
GOM
ATOS
ATOS I
ATOS II
TRITOP
3D Scanners
FAROARM
Minolta
steinbichler
7) MOST IMPORTANT OF ALL, Is there any scanner availible in market that provides an accuracy of 5-10 microns.
8)Does 3D Scanners really provides the accuracies their manufacturers claim. I remember reading somewhere the claim of GOM for an accuracy of upto 2 micron. Is it possible to attain this much accuracy on a 3D Scanner?
9)Can Todays scanners provide an accuracy equal to that of a CMM? Can somebody provide me some comparison between CMM and 3D Scanner in terms of accuracy?
I would really appreciate the comments, personal experiences of people invloved in this technology.

RE: 3D Scanning Systems comparison
Really the only ways you'll find out is to get them to give a demo, or pay them to do a job for you, on a known property.
5-10 microns is a pretty aggressive target for anything shy of a clean room facility by the way.

RE: 3D Scanning Systems comparison
There are companies in the jet engine turbine blade industry obtaining .0005 in accurracy over the entire turbine blade. As Greg mentioned the 5-10 microns would be difficult to achieve with any of the devices you listed.
RE: 3D Scanning Systems comparison
I use the Faro Platnum scan arm with the Faro Laser.
By the time you scan, Clean the scan, relax the polygon mesh then go to surface, were lucky to get within 0.001".
With the automotive stampings and molds we deal with, this is plenty good. Brown and sharp has a scanner that mounts to a bridge type cmm that might be close to what you want to hold, but like it was said before, put on your white jump suit and scan in a clean room.
