They have. These 3D printed structures are stronger than machined equivalents.

BS! You can cast squares with hollow inside!

Not really!
Can you 3D print with titanium (used in aerospace extensively) or 304 SST etc...?
These 3D printed metals are not stronger than cast metal, I think!

Not really!Absolutely. Turbine fans in jet engines are now being 3D printed from titanium.

These 3D printed metals are not stronger than cast metal, I think!You think wrong. The ability to finely control the temperature allows
for very precise tempering. In many applications the result is a
stronger alloy than you have starting with a solid material and
machining parts of it away.
3D printing also allows the use of alloys that are not readily
castable, opening up new possibilities for designs. (And, of course,
3D printing allows for entirely new designs that are impossible to
make using any other technology.)

Also, there is extruding, round, squared tubing, window frames etc...
Lot faster than 3D printing.
3D printing machines are expensive too.

Dreaming!!!This is not the future. It is now. Standard manufacturing practice in
many industries, with many materials.

What makes any metal stronger is forging!
That's what black smiths do all day, heating and hammering the metal!
Just heating and fusing metal powder together with laser is just like casting! >Metal stays brittle, cracks, breaks easy, like any cast iron!
Had my share of metallurgy back in engineering school, 40 years ago.

You are 40 years behind the times in your knowledge of metallurgy.

Once I bought some new, cheap Chines made hammer sets on the flee market! Turned out , it was made out of cast iron.
All broke within a year or so, only used them a few times.
I think, you frying pan handle would break first, very quickly!
