I make parts for 3D industrial printers that run $1+ million...and they don't have the footprint to print up a bike frame...not even close (well, maybe a frame for 12" wheels ).
Steel feels soft and springy indeed, and i do enjoy my steel Basman over aluminium one for chilled out rides. Great opportunity to compare materials directly, since the geometry is same and components used in builds are similar as well, steel forks are way softer then aluminium ones too. But for many purposes when weight matters, like when you travel, or need to take a bike to the train, or want to get somewhere really fast, aluminium is a good choice.Steel is real! Nothing feels like it. I don't enjoy the harsh feel of aluminum, I don't think carbon is durable enough, I don't trust iits longevity, and if you chip it, it's toast!
I haven't tried titanium, but if anyone has a large ti frame, maybe 97 Kona King Kahuna, I'd be glad to take it for some long term testing...
Until then, make mine cro-mo!
May also depend on the frame geometry. Not so big of a difference on a normal cruiser, but on a long stretch cruiser there is moreI have mild, hi-ten, chromoly, and aluminum frames, and, quite honestly I can't feel this harshness or spongy-ness that people talk about. I feel weight...but not 'flex'.
Might be a princess and the pea thing...and I ain't no princess .
Solid point...but, I have a lot of bmx bikes as well...and there is no end to comments on such and such frame is harsh, or spindly, or whatever. I have no experience racing off a gate, so that may be where all this flex is felt. Lots of comments on mountain bikes as well, don't feel it there either. Hoping to start getting some track time this summer, so maybe I'll begin to notice this mystical sponginess once I get some gate starts under my belt .May also depend on the frame geometry.

Your basic premise was considered true up until the last couple decades. It has now been determined that all metallic materials will eventually fail due to fatigue from even very small loads, far below the fatigue limit, with enough cycles. This didn't take scientists to figure out, plenty of car guys have noted this in suspension components of cars with no rust issues or impact evidence...control arms, especially, sag/twist/deform after several decades of normal driving.I use steel because it has no fatigue limit. A 225 pound man could ride a steel bike over 100 years and it would still be like new. If a 125 pound man were to ride aluminum for 20 years, it would break. Carbon would break if it was to be ridden by a 100 pound man for 20 years.
STEEL IS REAL!
