Magnesium Wheel scan

Video of how I scanned an ultra rare car wheel with POP with some good ol Blender and Solidworks fun at the end. Scanner was ideal for catching all those sculpted curved edges.


Great job!
The video is very well made and is very interesting


Very kind comments - more to come.

If anyone has any requests, please send them in - the trickier the better :wink:


Brilliant! Thanks for that… about to try something similar.

It’s the cleanup I struggle with. What is your typical process for items with a mixture of curves and sharp edges? Including correcting it in cad. I know it is a big ask.

Tricky answer, but here goes :

The key in my opinion is preparation which is why I am trying to show that in the ‘consideration’ section. Once you have a good scan you dont need much post processing or correcting. Ideally you want to avoid this unless you’re smoothing or cutting other objects out / pasting them in.

Similar to photo editing, the better the source info, the better the result.

Understand what the scanner can and cant do and use it as a tool, not a silver bullet. For example in the wheel you simply cannot scan the whole thing in one go - I mean you could but it would take you a long time and many many attempts with no real benefit. This is why I scanned an effective cross section only.

For edges and hollows, a mix of taclum powder brushed and ever changing gain settings - I keep a constant eye on the IR trace mainly and trust the scan is working. The trace should ideally be a light grey, not in ‘white out’ which is effectivly dazzling the scanner or in photography terms, over exposure.

Edges are tricky because they can be highly reflective, so the powder dulls the shine but you also need to lower the gain - also experiment with the orientation of the scanner, turn it 90 degrees and see what works. Hollows are dark, so again the powder increases reflectivity but also you need to raise the gain this time, especially as you may be forced further back.

I tried to show this in the video if that helps.

Lastly - practice, practice and practice. I usually scan an object 2-3 times and pick the best result.
Been scanning for 10+ years and still learning loads.

If you find it helpful please consider supporting my videos, it encourages me to make more :slight_smile:
