Francois, to many, 3D printing is interpreted as many guises.
For me in Singapore, I am now experimenting with recreating the FRONTAL part of a watch case which I have the CAD diagram.
In the future, this year, I hope to be able to scan a case part, and recreate it.
I can do it in metal.
Or several materials.
It is GREAT fun for watch people.
Now, what I am aiming to do...is to do a surface scan of my new watches, and keep the CAD scan in software.
Then, if the watch is scratched, I want to BUILD a layer of gold, steel or ti on top of the original watch case, and then polish it down to a BRAND NEW restored case.
If I can do it, we can wear our watches more confidently, not afraid of scratching it.
The technology exists, but raw....I have a reasonable, well, by my standards, machine that I can recreate a solid gold case...EXACTLY.
I can even scale it up/down in size.
I also wish to make COMPLETE sapphire or hard scratch proof cases from my current watches...and play around first.
Look at the new RM watches, ideal...small production, and exotic shapes.
