illiGood definition can be had with current technology. A small nozzle on a well-configured printer using appropriate printing settings will make all the difference in the world. Other than that, you can sand and polish prints to make them look better.
Take a look at these prints, which show how much definition you can get when printing and post-processing:

(You can also check out the "Made" tab to see how different printers vary wildly in quality)
Oh, no. I did check out the link you provided.
But they're all just renders and not real products. Like the description says, "digital photo".
And the pic with real products like Topre Small Fry just looks like a 5 year-old painted it.
The details are messy and edges rough.
I hope you don't take it personally...
