As an example a Sugar Bowl and Spoon was 3D printed for the CT Scanner Facility (Figure 1) all clients are welcome to come and make use of this with their free coffee. This was a great opportunity to show how these techniques (3D Scanning and Printing) can be used in conjunction. The sugar pot …

Over the past year we have made significant advances in our analysis capabilities on CT data. The main addition to our skillsets is the ability to perform more advanced segmentation on samples with small differences in density. In the case of most CT data sets this is the most difficult part, since in general parts …

Raman spectroscopy is a powerful technique which allows materials to be discriminated from each other based on their Raman spectral fingerprints. It is used for qualitative testing of material types, eg. testing if milk powder contains melamine, or can be used for quantitative investigations by setting up calibration models. We have available a newly installed …

No we cannot CT scan your whole swimming pool, not non-destructively anyway. What we can do is take a sample of fibreglass from where the weir is cut out, and analyze that section. In this example, two samples of different fibreglass pool manufacturing methods are compared. These are the chopper gun application (sample 1) and …

In this proof of concept, a damaged HV insulator used in power line transmission was scanned to see if internal damage can be assessed positively. The idea is to scan these objects preventatively before serious failure. Some images show the damage subsurface and the clarity of routine-type 3D X-ray inspection.
