Not a bad idea, but I doubt it would have a lot of demand and I would need to purchase the 3D printing license, but not a bad idea
I was confused about the need to purchase a 3D printing license, but I see that Daz requires a separate Commercial 3D Print License that "allows you to print and sell up to twenty prints of that piece of content." Oh wow! I was not aware of that restriction.
That being said, although I would love to have a 3D print of these girls, I know that it would not be easy.
I have several 3D printers at home and at work, and I can tell you that printing hair is a nightmare.

Printing curly hair that is not stuck to the body is virtually impossible.


The hair would need a lot of supports and would probably break too easily. Same for the fishnet bikini: the parts that are stuck to her skin would be easy to print, but the parts that are loose would need a lot of supports and would probably break. Besides, the fishnet would be barely visible except if the print nozzle has a very small diameter (<0.2mm), but then the print would take several days.
And then there is the issue of colors. Most of the reasonably priced 3D printers would be limited to five colors (Prusa Mk4 with MMU3 or Prusa XL with five toolheads) or four colors (Bambulabs with AMS). This is certainly not enough to support all these skin tones, hair colors, and bikini colors. So the solution would be to print these girls in a neutral color and then paint them by hand. But then this means several hours of preparation, painting and post-processing for each 3D print.
So... nice in theory, but not so easy in practice.
