Quick visual comparison between the Ryet Aircode 3D printed saddle and the Goldix 3D printed saddle that's available from like $17-25 USD during sales. The Goldix saddle seems to be well built, with a stiff carbon shell and thick rails. The 3D mesh also has a bit more cushion, while the bottom edges of the carbon seem to be more rounded. There's also a 1cm lip that protrudes from the back end of the saddle to give a bit more length.
The two saddles seems similar. I'll report back on the actual ride quality once I put a few km/mi on it.
UPDATE: I just took this saddle for a ride and it felt great! No discomfort, plenty of cushion, stayed cool in the California sunshine and minimal friction when adjusting position. Unfortunately it seems the price has jumped up from it's earlier low price!
