And I live on the East coast in PA right on the boarder of PA and NJ. I can see the sign now DIY East Coast Custom Audio. We can offer a walk in service and have a 2 day turn around for a small fee.

"2 day turn around" -- I can see piotrus-g falling out of his chair laughing. That would require a good stock of drivers sitting on the shelf and a bit of magic to go from ear molds to shells in less than a day. The manpower to do that on a commercial scale would need to be pretty large. But, hey? Dream big or go home, right?

Ok 2 day turn around for specific models we will have the drivers wired and tubed and they will just have to installed and trimmed. And we won't be using negative molds it will all be 3D scanned and sent to a high RPM 5-axis mill and will be milled out of a solid block of acrylic or carbon fiber to cut down on manufacturing time.

Remember we just won 40 million dollars we are going state of the art.

Yeah, I forgot about being a millionaire. Can't get out of my thousandaire thinking.

But I get the sense that cnc'ing a block of acrylic isn't going to save that much time since the entire process will require hi-res scanning, programming, cutting, then extensive sanding and polishing? Compare that to making a negative, pouring/curing the acrylic.

Once your technique is perfect enough, shell making can be done (that includes waxing, making negative mould, moulding, grinding, drilling) in half an hour. Not that much difference compared to 3d tech I might say.
 
The only drawback I can see here is that conventional method is more labor intensive, which is a big minus when you want to go full throttle.

Thats true, I have done both and it takes more time for digital process. But I am not a pro so there was learning experience on both accounts.

For 40 million you guys could buy some existing company, and simply impose your ideas over it. Use the rest 30 to go on nice vacations it's so much easier and cost effective

How did they take picture of the IEM without using bluetak to make them stand?  
Any trick?

Spoiler: Warning: Spoiler!

 

 

 
It would be very easy to digitally remove the blutac, using Adobe Photoshop

Nice, what are you using to color the acrylic?

Those small bottle of acrylic dye you buy from your local art friend store.

I presume that stuff is water-soluble, or it might denature the acrylic.
 
What about UV resilience of the dye? If it's intended for food, I wouldn't expect it to have much UV resistance...
