This example shows a small section of material scanned using nanoCT and analyzed for fibre thickness and angular distribution
Very short video of the CT slices: fibres
One application of nanoCT scanning is to measure coating thickness of paint coatings for example. In this case a cardboard packaging material has its paint coating analyzed with a colourmap showing the thickness distribution.
It was women’s day recently in South Africa so we scanned a flower and made a digital colourful mesh, which you can open in any CAD program or even windows10 can open it in 3D. Find the files on thingiverse here: https://www.thingiverse.com/thing:3843542
Also see the video here and send someone a digital flower : FLOWER
This video shows the generation of a tetrahedral mesh from a microCT scan – tetmesh_small
This is a new functionality in Volume Graphics VGSTUDIO MAX 3.3. We can do this for you with any 3D data. See more at www.sun.ac.za/ctscanner for this and other 3D image analysis services. This example is a tensile dogbone sample in cast Ti6Al4V, with large casting pores in the middle.

A nautilus shell is analyzed here using a nanoCT scan and 3D image analysis powered by VGSTUDIO MAX.
For more about this interesting natural structure have a look at wikipedia here, the analysis is meant to show how nanoCT can visualize and analyze interesting structures in full 3D, as in the video and images below.

Good news for hands-on students and engineers – we are renting out our Artec Eva and Artec Spider scanners on daily, monthly and annual rates. Do your own scanning, with the best handheld scanners around.
Examples of scans can be found here: https://lnkd.in/gVxjZVx
Specs of scanners:
Pricing as follows for both scanners together (daily, monthly, annual rates in that order, excluding 7% admin fee and 15% VAT):
Academics & students: R1000 per day, R10 000 per month, R100 000 per year
Industry: R2000 per day, R20 000 per month, R200 000 per year
Minus 25% from above prices for only one scanner at a time
This case study is meant to explain that our CT scan services are international – there is no need to be here on location for scanning and shipping most typical samples are no problem at all. The advantage? The price! The price of CT scans is much lower here than in your local CT service lab. So to make a case study of this we scanned a South African 2 Rand coin and a 2 Euro coin, as well as my credit card. All images here are from CT scans – and imaged using VGSTUDIO MAX 3.2. No coins or credit cards where harmed in the making of this case study (totally non-destructive process).
First up – the Euro (video here – Euro video):
Now for the South African Rand (video here 2 Rand):
Now, we take apart the Euro (video here euro take apart):
For viewing the Euro and Rand side by side – see this video Euro and Rand
Comparing the Rand to the Euro – clearly the Euro is thicker:
And overlapping them – it seems there are mostly major deviations between Euro and Rand.
So can you pay by credit card? yes you can. Here is an example of a X-ray of a credit card with chip (and small crack in plastic):
Also see the CT scan of the chip in this video and image below: credit Card Chip Wall Thickness
We hope you enjoyed this case study. On a more serious note – if you know microCT scanning and want to send us your parts you are welcome – we offer international CT scan and analysis services on hourly rates of $165 (US). If you are unsure please see the “make an order” tab or contact us to make you a quote. For international shipments, please add clearly to the package “for testing only – nominal value $1” to ensure no delays and simplify the process, and please use dedicated courier services (e.g. DHL), not postal services.
This is one of the best-known applications of X-ray inspection and CT scanning – to check cast metal parts for porosity and extent of porosity. Here one example with nice video showing the data and results available for such parts.
