It’s a fully 3D printed titanium bike unlike anything else in the word. Naturally we interviewed the designer and got details.
The bearings must sound like total crud. Or maybe they are not 3D printed. If they just printed the parts then okay, probably it’s not fast but I would watch the first 15 minutes just for fun.
It seems that “fully” 3D printed is an overstatement. The article says, “there’s 3D printing whenever possible”. That includes printing the frame as a single piece, and the hubs. Some pieces are specified to not be 3D printed like the crank and saddle. The article doesn’t mention bearings.
You could definitely 3D print smooth bearings, 3D printed metal can be very smooth after it’s polished. Printing titanium is a whole different game compared to the FDM printing most people are familiar with.
