3D Model of a Dime, Update
Although Zeiss' CT scan data is exceptional, the 3D model is still a work in progress.
Zeiss provided multiple excellent scans of two plastic replicas of a Dime. The average resolution of the scans is .032mm (.0013"). While all the details are clearly visible (even John Sinnock's initials below Roosevelt's bust), the surface is a little noisy as if the Dime was made of fine sandpaper.
Using Rapidform XOR software, I've created a pretty smooth version of the dime, but have lost some details. You can still see the "JS", but not clearly. I've submitted a request for assistance to Rapidform. Hopefully, they'll be able to show me how to do a better job of smoothing the data to create a nicer 3D model of a Dime...

3D Model of a Coin
3D Model of a Coin
Using Zeiss' X-Ray Computed Tomography (CT) scanning service to create high resolution CAD model of a Dime (10 cent piece).
Normally, a Dime would not be a good subject for CT scanning; coins are relatively small with intricate detail and are made of dense metals. To get around the density issue, I used very low shrinkage silicone rubber to create molds of both sides of a Dime. I then cast urethane plastic replicas and sent the replicas to Zeiss for scanning. Careful vacuum degassing of the silicone and urethane was critical to capturing the intricate details.
Zeiss' Metrotom 800 CT scanner is able to capture very small details, as small as .01mm in some cases. It is also accurate to +/-.0045mm. The high resolution and accuracy coupled with the carefully crafted replicas should produce exceptional CAD models...

3D Model of Aircraft Longeron
3D Model of Aircraft Longeron
Reverse Engineered cracked longeron, designed doubler (splice) and provided adaptive machining 3D model using ZScanner 800, Rapidform XOR software and Solid Edge CAD software.
Client provided: 1. four foot long cracked section of longeron removed from aircraft 2. two foot long plaster cast of inside surface of remaining section of longeron (mating surface for doubler) 3.six foot long pre-machined blank for replacement longeron with integral doubler.
All 3 components were scanned using ZScanner and then modeled (minus crack) using Rapidform to create Parasolid 3D models. Solid Edge was used to 'assemble' 3D models and to design replacement longeron with inegral doubler inside pre-machined blank to insure 100% cleanup and to equalize material removal. Client was pleased with results.

3D Models from CT Scan STL
3D Models from CT Scan STL
Client was very impressed with CT results. 3D models of components revealed significant voids in prototype product. 3D model of assembly revealed interference between prototype components. Client now plans to expand use of Zeiss' X-ray Computed Tomography (CT). Multiple products will benefit from 3D models created from CT scan STL mesh.
Rapidform XOR3 and EXPLORER software modules were used to analyze STL mesh created using Zeiss CT scan technology. STL data was extremely high resolution which allowed creation of very accurate and very detailed 3D models, which enabled determination of cause of product non function and which allowed characterization of voids in material. Dimensional analysis using Zeiss' CAD to scan comparison technology was very beneficial as well.
