Here an image if you have trouble with the video:

Foam structure analysis

In this example a nanoCT scan of a 3 mm section of rigid foam is used to demonstrate the analysis of connected pore spaces. For more technical details please contact us, the images speak “volumes” by themselves:

NanoCT of woven material

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

NanoCT of cardboard

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.

This is the 4 mm sample loaded for a scan

Flower for Womens day

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

Full volume tetrahedral mesh from microCT data

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. Previous work on this topic using direct voxel-based simulation can be read here: https://lnkd.in/gGaAiaP. Enjoy the video! StellenboschCTfacility microCT simulation 3Dmesh

Nautilus nanoCT

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.

Coffee bean nanoCT scans

This study in collaboration with Dr Karen Cloete from iThemba Labs includes some great coffee bean images and a great video can also be seen here. Find the full paper here: https://doi.org/10.1016/j.fochx.2019.100032

International CT scans

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.
