Again, you are talking about niche applications and landing gear are not
that big a part of an aircrafts weight.

An irrelevant red herring to the subject of 3D printing. There are a HUGE
number of different composite materials out there and it has taken well
over half a century for most aircraft to have even a small fraction of
composite materials in their construction.

Note the word "most".

Whoopee. It is still niche.

Does anyone care about a shape optimized 4 slice toaster or filing cabinet?
