Reverse engineering a drone blade

This examples shows a microCT scan of a drone blade – with the creation of a volume mesh – useful for reverse engineering or simulation.

Enjoy 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.
